Seminar on Ubiquitous Computing

UBIQUITIOUS COMPUTING Varun. R USN- 1RE08EC110 Reva Institute of Technology and Management Bangalore. [email  protected] com Abstract- The highest ideal of ubicomp is to make a computer so imbedded, so fitting, so natural, that we use it without even thinking about it. One of the goals of ubiquitous computing is to enable devices to sense changes in their environment and to automatically adapt and act based on these changes, based on user needs and preferences.The technology required for ubiquitous computing comes in three parts: cheap, low- power computers that include equally convenient displays, a network that ties them all together, and software systems implementing ubiquitous applications. Keywords— ubicomp, nanotechnology Introduction Ubiquitous computing (often abbreviated to â€Å"ubicomp†) refers to a new genre of computing in which the computer completely permeates the life of the user. In ubiquitous computing, computers become a helpful but invisible force, assisting the user in meeting his or her needs without getting in the way.Mark Weiser, the originator of the term â€Å"ubiquitous computing†, â€Å"described it this way: â€Å"†¦ [Ubiquitous computing’s] highest ideal is to make a computer so imbedded, so fitting, so natural, that we use it without even thinking about it. † It is also referred to as Pervasive computing. Pervasive computing environments involve the interaction, coordination, and cooperation of numerous, casually accessible, and often invisible computing devices. These devices will connect via wired and wireless links to one another as well as to the global networking infrastructure to provide more relevant information and integrated services.Existing approaches to building distributed applications, including client/server computing, are ill suited to meet this challenge. They are targeted at smaller and less dynamic computing environments and lack sufficient facilities to manage changes in the network configurations. Networked computing devices will proliferate in the user’s landscape, being embedded in objects ranging from home appliances to clothing. Applications will have greater awareness of context, and thus will be able to provide more intelligent services that reduce the burden on users to direct and interact with applications.Many applications will resemble agents that carry out tasks on behalf of users by exploiting the rich sets of services available within computing environments. Our preliminary approach is to activate the world and provide hundreds of wireless computing devices per person per office, of all scales. This has required network in operating systems, user interfaces, networks, wireless, displays, and many other areas. We call our work as â€Å"ubiquitous computing†. This is different from PDA’s, dynabooks, or information at your fingertips.It is invisible; everywhere computing that does not live on a personal device of a ny sort, but is in the woodwork everywhere. Nanotechnology and Wireless Technology If computers are to be everywhere, unobtrusive, and truly helpful, they must be as small as possible and capable of communicating between themselves. Technological movements supporting these goals are already well underway under the rubrics nanotechnology and wireless computing. Nanotechnology The trend toward miniaturization of computer components down to an atomic scale is known as nanotechnology.Nanotechnology involves building highly miniaturized computers from individual atoms or molecules acting as transistors, which are the heart of the computer chip. The number of transistors in a chip is indicative of its power. Therefore, nanotechnology’s extreme miniaturization of transistors allows for impressive levels of computing power to be put into tiny packages, which can then be unobtrusively tucked away. Wireless Computing Wireless computing refers to the use of wireless technology to connec t computers to a network.Wireless computing is so attractive because it allows workers to escape the tether of a network cable and access network and communication services from anywhere within reach of a wireless network. Wireless computing has attracted enormous market interest, as witnessed by consumer demand for wireless home networks, which can be purchased for several hundred dollars. Context-Awareness and Natural Interaction Small computers that communicate wirelessly provide a necessary infrastructure for ubiquitous computing. However, infrastructure is only half of the battle.As noted above, the ubiquitous computing movement aims to make computers more helpful and easier to use. Indeed, computers should be able to accurately anticipate the user’s needs and accommodate his or her natural communication modes and styles. These themes are captured with-in the ubiquitous computing movement’s focus on context-aware computing and natural interaction. Context-Awarenes s The promise of context-awareness is that computers will be able to understand enough of a user’s current situation to offer services, resources, or information relevant to the particular context.The attributes of context to a particular situation vary widely, and may include the user’s location, current role (mother, daughter, office manager, soccer coach, etc. ), past activity, and affective state. Beyond the user, context may include the current date and time, and other objects and people in the environment. The application of context may include any combination of these elements. For example, a context-aware map might use the information that the user is away from home, has no appointments, and that the time is 6:00 in the evening to determine that the user could soon be interested in dinner.It would then prepare to offer the user guidance to nearby restaurants should he or she makes such a request. Natural Interaction Currently, using the computer is part of the task we are attempting to accomplish—something else to focus on, learn, or do in order to accomplish a goal. The idea behind natural interaction is for the computer to supply services, resources, or information to a user without the user having to think about the rules of how to use the computer to get them. In this way, the user is not preoccupied with the dual tasks of using the computer and getting the services, resources, or information.Donald Norman, a well-known researcher in human–computer interaction, once said that he doesn’t want a word processor; he wants a letter writer—something that will allow him to get the job done of writing a letter, without the instrument getting in the way. UbiquiTrain The UbiquiTrain system is based on a database of training content to which users connect via desktop computers and wireless handheld systems. UbiquiTrain loads training content according to an algorithm that includes a number of context-related cues. The first cue centers on the user’s schedule.For example, if there is an upcoming meeting called by the user, UbiquiTrain would load training content on how to lead meetings. As the meeting time approaches, this training content floats to the top of the list of topics available. A second cue invokes the context of the user’s current activities. If the user is working on a task related to an item on his or her to-do list, UbiquiTrain would load corresponding content, as well. For example, the user working on a proposal would cue UbiquiTrain to call up training content on written communication in general and proposal writing in particular.UbiquiTrain holds content at the ready should users ask for it. The system does not demand the user’s attention. As befits the nature of ubiquitous computing, users interact with UbiquiTrain in the way that feels most natural to them. Some users talk to the system, asking it to show them a particular piece of training content. Other s, not yet comfortable with talking to a computer, use the touch screen. UbiquiTrain reacts to the user, as well. Noting the confusion on the user’s face as it explains how to deal with attendees who derail meetings, for example UbiquiTrain tries explaining the concept a different way.It then offers a short video example. Observing that the user is nodding, UbiquiTrain resumes the normal course of training. Of course, if users are looking for information on a particular topic, they can skip straight to the content simply by asking for it. UbiquiTrain is flexible enough to understand the different ways users might request a given piece of content. UbiquiTrain is more than a means to deliver already-developed training content. The system also offers important benefits in training needs assessment by monitoring trends in training content demands across users.The system takes action when it senses a trend in demand for certain broad areas of training content among members of part icular departments or among workers with similar duties across different departments. As a means of respecting user’s privacy, the system polls them and asks if they would like to request in-depth training on the topic, taking suggestions for areas in which users might want particular detail. If sufficient interest is found, the results are then forwarded to the group responsible for training in the organization. By observing trends in content demand, UbiquiTrain can also sense when its database is incomplete.If users ask for content that doesn’t exist in the database, the request is logged. If a sufficient number of similar requests are received, the system generates a requisition for new content. In this way, the database stays current with the needs of its users. Finally, UbiquiTrain can help evaluate the training it has delivered. The most overt way is to ask the user for feedback on the training received. A second way is have the user request relevant coworkers to evaluate him or her in a given area at a given time, if appropriate. The rating task, of course, is administered by UbiquiTrain through the coworkers’ computers or handhelds.Raters can choose to make their ratings and comments anonymous, if they wish. Once all of the data are compiled, UbiquiTrain feeds them back to the user and offers appropriate development suggestions. The system makes use of the data, as well, to track the effectiveness of the training it has delivered. Clearly, UbiquiTrain offers important benefits to all constituents. Users have a convenient, up-to-date training tool that unobtrusively responds to their needs. At the corporate level, the training needs within the organization are easily tracked and clearly delineated and can be analyzed to fine detail. Current Embedded TechnologyEmbedded technology is the process of introducing computing power to various appliances. These devices are intended to perform certain specific jobs and processors giving the c omputing power are designed in an application oriented way. Computers are hidden in numerous information appliances which we use in our day to- day life. These devices find there application in every segment of life such as consumer electronics, avionics, biomedical engineering, manufacturing, process control, industrial, communication, defence etc†¦ Embedded systems, based on there functionality and performance requirement are basically categorized as: i.Stand alone systems ii. Real time systems iii. Networked systems iv. Mobile devices Stand alone systems work in stand alone mode, taking inputs and producing desired outputs. They do not have any dependence on other systems. Embedded systems in which some specific work has to be done in a specific time period are called Real time systems. Meeting the dead line is the most important requirement of a real time system. In Hard real time systems, missing a deadline may lead to a atastrophe and in Soft real time systems such proble m is not present.Systems which are provided with network interfaces and accessed by networks such as LAN or the Internet are called Networked Systems. Networking may be wired or wireless. Mobile devices are devices which move from one location to another, like mobile phones, PDA’S etc. Today, many people carry numerous portable devices, such as laptops, mobile phones, PDAs and mp3 players, for use in their professional and private lives. For the most part, these devices are used separately i. e. , their applications do not interact.However, if they could interact directly, participants at a meeting could share documents or presentations, business cards would automatically find their way into the address register on a laptop and the number register on a mobile phone, as commuters exit a train, their laptops could remain online; likewise, incoming email could now be diverted to their PDAs. In such a distributed environment where several embedded devices has to communicate and c o-ordinate with each other. For this a communication link is required which may be wired or wireless.In initial stages of Networked embedded system environments wired connection was preferred as it provided a safer and faster channel for communication. But the cost, immovability and the cables running around the floorboards became less attractive. On top of this, dishing out the cash for network cards, cables and a hub/switch reserved this practice to the more elite computer users, until wireless networking hit the scene. Infrared communication was initially used for wireless communication because of the low cost offered by it. But it suffered from the limitation that it can be used only within Line Of Sight. IEEE introduced 802. 1 as the international standard for wireless LANs. This used a 2. 4GHz transmission band while maintaining a steady 1-2 Mbps bandwidth rate. Being that this was extremely slow compared to 100Mbit wired LANs, it took a while for the 802. 11 standard to devel op into a viable solution, achieved shortly after with the 802. 11a, b and g standards, offering bandwidth ranging from 11Mbps to 54Mbps. Although this is still considerably short of the 100Mbit found in cabled networks, 802. 1 x wireless technologies is now literally regarded as the future of networking. Bluetooth, Wi-Fi, Wi-Max are the latest solutions, under the 802. x standard, for wireless communication over short, medium and long range communication respectively. Pervasive Computing Earlier in this paper, we characterized a pervasive computing environment as one saturated with computing and communication capability, yet so gracefully integrated with users that it becomes a ‘‘technology that disappears. ’’ Since motion is an integral part of everyday life, such a technology must support mobility; otherwise, a user will be acutely aware of the technology by its absence when he moves. Hence, the research agenda of pervasive computing subsumes that of mob ile computing, but goes much further.Specifically, pervasive computing incorporates four additional research thrusts into its agenda, as illustrated by Figure 1. Effective Use of Smart Spaces The first research thrust is the effective use of smart spaces. A space may be an enclosed area such as a meeting room or corridor, or it may be a well-defined open area such as a courtyard or a quadrangle. By embedding computing infrastructure in building infrastructure, a smart space brings together two worlds that have been disjoint until now [16]. The fusion of these worlds enables sensing and control of one world by the other.A simple example of this is the automatic adjustment of heating, cooling and lighting levels in a room based on an occupant’s electronic profile. Influence in the other direction is also possible — software on a user’s computer may behave differently depending on where the user is currently located. Smartness may also extend to individual objects, whether located in a smart space or not. Invisibility The second thrust is invisibility. The ideal expressed by Weiser is complete disappearance of pervasive computing technology from a user’s consciousness. In practice, a reasonable approximation to this ideal is minimal user distraction.If a pervasive computing environment continuously meets user expectations and rarely presents him with surprises, it allows him to interact almost at a subconscious level [46]. At the same time, a modicum of anticipation may be essential to avoiding a large unpleasant surprise later — much as pain alerts a person to a potentially serious future problem in a normally-unnoticed body part. Localized Scalability The third research thrust is localized scalability. As smart spaces grow in sophistication, the intensity of interactions between a user’s personal computing space and his surroundings increases.This has severe bandwidth, energy and distraction implications for a wireless mobile user. The presence of multiple users will further complicate this problem. Scalability, in the broadest sense, is thus a critical problem in pervasive computing. Previous work on scalability has typically ignored physical distance — a web server or file server should handle as many clients as possible, regardless of whether they are located next door or across the country. The situation is very different in pervasive computing.Here, the density of interactions has to fall off as one moves away — otherwise both the user and his computing system will be overwhelmed by distant interactions that are of little relevance. Although a mobile user far from home will still generate some distant interactions with sites relevant to him, the preponderance of his interactions will be local. Like the inverse square laws of nature, good system design has to achieve scalability by severely reducing interactions between distant entities. This directly contradicts the current etho s of the Internet, which many believe heralds the ‘‘death of distance. ’’Masking Uneven Conditioning The fourth thrust is the development of techniques for masking uneven conditioning of environments. The rate of penetration of pervasive computing technology into the infrastructure will vary considerably depending on many non-technical factors such as organizational structure, economics and business models. Uniform penetration, if it is ever achieved, is many years or decades away. In the interim, there will persist huge differences in the ‘‘smartness’’ of different environments — what is available in a well-equipped conference room, office, or classroom may be more sophisticated than in other locations.This large dynamic range of ‘‘smartness’’ can be jarring to a user, detracting from the goal of making pervasive computing technology invisible. One way to reduce the amount of variation seen by a us er is to have his personal computing space compensate for ‘‘dumb’’ environments. As a trivial example, a system that is capable of disconnected operation is able to mask the absence of wireless coverage in its environment. Complete invisibility may be impossible, but reduced variability is well within our reach. [pic]This figure shows how research problems in pervasive computing relate to those in mobile computing and distributed systems. New problems are encountered as one move from left to right in this figure. In addition, the solution of many previously-encountered problems becomes more complex. As the modulation symbols suggest, this increase in complexity is multiplicative rather than additive — it is very much more difficult to design and implement a pervasive computing system than a simple distributed system of comparable robustness and maturity. Note that this figure describes logical relationships, not temporal ones.Although the evolution o f research effort over time has loosely followed this picture, there have been cases where research effort on some aspect of pervasive computing began relatively early. For example, work on smart spaces began in the early 1990’s and proceeded relatively independently of work in mobile computing. Figure 1: Taxonomy of Computer Systems Research Problems in Pervasive Computing Example Scenarios What would it be like to live in a world with pervasive computing? To help convey the ‘‘look and feel’’ of such a world, we sketch two hypothetical scenarios below.We have deliberately chosen scenarios that appear feasible in just a few years. These examples use Aura as the pervasive computing system, but the concepts illustrated are of broad relevance. Scenario 1 Jane is at Gate 23 in the Pittsburgh airport, waiting for her connecting flight. She has edited many large documents, and would like to use her wireless connection to e-mail them. Unfortunately, bandwid th is miserable because many passengers at Gates 22 and 23 are surfing the web. Aura observes that at the current bandwidth Jane won’t be able tofinish sending her documents before her flight departs.Consulting the airport’s network weather service and flight schedule service, Aura discovers that wireless bandwidth is excellent at Gate 15, and that there are no departing or arriving flights at nearby gates for half an hour. A dialog box pops up on Jane’s screen suggesting that she go to Gate 15, which is only three minutes away. It also asks her to prioritize her e-mail, so that the most critical messages are transmitted first. Jane accepts Aura’s advice and walks to Gate 15. She watches CNN on the TV there until Aura informs her that it is close to being done with her messages, and that she can start walking back.The last message is transmitted during her walk, and she is back at Gate 23 in time for her boarding call. Scenario 2 Fred is in his office, fr antically preparing for a meeting at which he will give a presentation and a software demonstration. The meeting room is a ten-minute walk across campus. It is time to leave, but Fred is not quite ready. He grabs his PalmXXII wireless handheld computer and walks out of the door. Aura transfers the state of his work from his desktop to his handheld, and allows him to make his final edits using voice commands during his walk. Aura infers where Fred is going from his calendar and the campus location racking service. It downloads the presentation and the demonstration software to the projection computer, and warms up the projector. Fred finishes his edits just before he enters the meeting room. As he walks in, Aura transfers his final changes to the projection computer. As the presentation proceeds, Fred is about to display a slide with highly sensitive budget information. Aura senses that this might be a mistake: the room’s face detection and recognition capability indicates tha t there are some unfamiliar faces present. It therefore warns Fred. Realizing that Aura is right, Fred skips the slide.He moves on to other topics and ends on a high note, leaving the audience impressed by his polished presentation. Missing Capabilities These scenarios embody many key ideas in pervasive computing. Scenario 1 shows the importance of pro activity: Jane is able to complete her e-mail transmission only because Aura had the foresight to estimate how long the whole process would take. She is able to begin walking back to her departure gate before transmission completes because Aura looks ahead on her behalf. The scenario also shows the importance of combining knowledge from different layers of the system.Wireless congestion is a low-level system phenomenon; knowledge of boarding time is an application or user-level concept. Only by combining these disparate pieces of knowledge can Aura help Jane. The scenario also shows the value of a smart space. Aura is able to obtain k nowledge of wireless conditions at other gates, flight arrival/departure times and gates, and distance between gates only because the environment provides these services. Scenario 2 illustrates the ability to move execution state effortlessly across diverse platforms — from a desktop to a handheld machine, and from the handheld to the projection computer.Self-tuning, or automatically adjusting behavior to fit circumstances, is shown by the ability to edit on the handheld using speech input rather than keyboard and mouse. The scenario embodies many instances of pro activity: inferring that Fred is headed for the room across campus, warming up the projector, transferring the presentation and demonstration, anticipating that the budget slide might be displayed next, and sensing danger by combining this knowledge with the inferred presence of strangers in the oom. The value of smart spaces is shown in many ways: the location tracking and online calendar services are what enable A ura to infer where Fred is heading; the software-controlled projector enables warm up ahead of time; the camera-equipped room with continuous face recognition is key to warning Fred about the privacy violation he is about to commit. Perhaps the biggest surprise in these scenarios is how simple and basic all the component technologies are.The hardware technologies (laptops, handhelds, wireless communication, software-controlled appliances, room cameras, and so on) are all here today. The component software technologies have also been demonstrated: location tracking, face recognition, speech recognition, online calendars, and so on. Why then do these scenarios seem like science fiction rather than reality today? The answer lies in the fact that the whole is much greater than the sum of its parts. In other words, the real research is in the seamless integration of component technologies into a system like Aura.The difficult problems lie in architecture, component synthesis and system-l evel engineering. Difference between traditional networking and pervasive computing These connections are fundamentally unlike those we associate with networks. Rather than using the network to connect computers that are being used directly by people, these appliances communicate over networks such that people do not directly monitor the communication between machines and programs.The majority of these communications will occur in an end-to-end structure that does not include a human at any point. The number of machines connected to the Internet has been increasing at an exponential rate and will continue to grow at this rate as the existing networks of embedded computers, including those that already exist within our automobiles, are connected to the larger, global network, and as new networks of embedded devices are constructed in our homes and offices.The kinds of devices that will be used to access the Internet are no longer confined to desktops and servers, but include small de vices with limited user interface facilities (such as cell phones and PDAs); wireless devices with limited bandwidth, computing power, and electrical power; and embedded processors with severe limitations on the amount of memory and computing power available to them. Many of these devices are mobile, changing not only geographic position, but also their place in the topology of the network. Unlike traditional Desktop Computers and existing networks, the new devices will have the following characteristics: 1.Many will have small, inexpensive processors with limited memory and little or no persistent storage. 2. They will connect to other computing elements without the direct intervention of users. 3. Often, they will be connected by wireless networks. 4. They will change rapidly, sometimes by being mobile, sometimes by going on and offline at widely varying rates. Over time, they will be replaced (or fail) far more rapidly than is now common. 5. They will be used as a source of infor mation, often sending that information into the center of the network to which they are attached.Ubi-Finger Here, in contrast, Ubi-Finger is the gesture-i/p device, which is simple, compact and optimized for mobile use. Using our systems, a user can detect a target device by pointing with his/her index finger, and then control it flexibly by performing natural gestures of fingers (Fig. 1). [pic][pic][pic] | | | | |By pointing a light and making| |The light will turn on! | |a gesture like â€Å"push a | | | |switch†. | | |Figure- 1 An example to control Home Appliances | [pic] Figure- 2 As shown in fig. 2, ubi-finger consists of three sensors to detect gestures of fingers, an infrared transmitter to select a target device in real world and a microcomputer to control these sensors and communicate with a host computer. each sensor generates the information of motions as follows: (1) a bending degree of the index finger, (2) tilt angles of the wrist, (3) operations of touch senso rs by a thumb.We use (1) and (2) for recognition of gestures, and use (3) for the trigger mechanism to start and stop gesture recognitition. Information Hoppers and Smart Posters Once these zones are setup, computers on the network will have some interesting capabilities. The system will help to store and retrieve data in an Information hopper. This is a timeline of information that keeps track of when data is created. The hopper knows who created it, where they were and who they were with. Another application that will come out of this ultrasonic location system is the smart poster.A convention computer interface requires us to click on a button on your computer screen. In this new system, a button can be placed anywhere in your workplace, not just on the computer display. The idea behind smart posters is that a button can be a piece of paper that is printed out and struck on a wall. Smart posters will be used to control any device that is plugged into the network. The poster will know where to send a file and a user’s preferences. Smart posters could also be used in advertising new services.To press a button on a smart poster, a user will simply place his or her bat in the smart poster button and click the bat. The system automatically knows who is pressing the poster’s button. Posters can be created with several buttons on it. Ultrasonic location systems will require us to think outside of the box. Traditionally, we have used our files, and we may back up these files on a network server. This ubiquitous network will enable all computers in a building to transfer ownership and store all our files in a central timeline. HAVi- An Implementation in Consumer Appliance EnvironmentHAVi is a standard for home appliances consisting of a set of APIs, services, and a standard for communication. HAVi’s primary goal is providing a dynamic service environment in which software components can discover and interact with other. It provides mechanisms fo r devices to discover, query and control other appliances on the home network, and provides system services such as message and event. Eight major consumer electronics manufacturers have come up with an open standard enabling home entertainment devices to communicate intelligently with each other.The HAVi(Home Audio Video Interoperability) standard promises to bring true platform independent interoperability to consumer devices using high bandwidth IEEE 1394 (FireWire) as the connecting medium. Major consumer electronics, software, semiconductor and computer manufacturers, namely Grundig, Hitachi, Panasonic, Philips, Sharp, Sony, Thomson and Toshiba along with now over 30 other participants, have formed a non-profit organization called HAVi (Home Audio Video Interoperability) for promoting the development of interoperable consumer products.The goal of HAVi organization is to provide a standard open architecture for intelligent audio and video devices to interoperate with each other regardless of manufacturer, operating system, CPU or programming language used for implementation. The simplest example can be time synchronization between different devices. TV set might get the correct time from the broadcast stream and the other devices can query the TV and set their own clocks according to it. Setting the VCR to record a program is a familiar situation users usually have problems with.With HAVi enabled devices this task can be made very easy. User can select the program he wishes to record with the Electronic Program Guide (EPG) residing on a digital TV set (or set top- box). The TV then locates an available recorder (e. g. , a VCR or a recording DVD device) and commands it to record the program supplying it with the time, length and channel parameters taken from the EPG. Thus, the user doesn’t need to program or touch the recording device in any way. The advantages of Pervasive Computing:We increasingly rely on the electronic creation, storage, and trans mittal of personal, financial, and other confidential information, and demand the highest security for all these transactions and require complete access to time-sensitive data, regardless of physical location. We expect devices — personal digital assistants, mobile phones, office PCs and home entertainment systems — to access that information and work together in one seamless, integrated system. Pervasive computing gives us the tools to manage information quickly, efficiently, and effortlessly.It aims to enable people to accomplish an increasing number of personal and professional transactions using a new class of intelligent and portable appliances or â€Å"smart devices† embedded with microprocessors that allow users to plug into intelligent networks and gain direct, simple, and secure access to both relevant information and services.. It gives people convenient access to relevant information stored on powerful networks, allowing them to easily take action an ywhere, anytime.Pervasive computing simplifies life by combining open standards-based applications with everyday activities. It removes the complexity of new technologies, enables us to be more efficient in our work and leaves us more leisure time and thus pervasive computing is fast becoming a part of everyday life. Concerns The power ubiquitous computing promises carries with it significant risks. One such risk is associated with the amount of privacy that must be sacrificed to see the benefits of truly helpful computers.Another is that early, â€Å"bleeding edge† applications of ubiquitous computing will turn out to be more ambitious than effective, leading some to prematurely conclude that the idea is a failure. We address each of these concerns below. Privacy Issues Simply put the more software tracks users, the more opportunities exist to trample on their right to privacy. To some degree, these issues are already being argued in the contexts of corporate e-mail snooping and the use of IT software that can track user activity down to the level of individual keystrokes.However, factoring in the idea of software that can track and act upon a user’s physical presence and form of activity leads to privacy concerns of a magnitude beyond those currently debated. The privacy implications of ubiquitous computing implementations must always be accorded the most careful consideration. Without powerful standards surrounding user privacy, the future world of ubiquitous computing may very well shift from one of ease and convenience to one where each of us has an inescapable sense of being watched, at best, and no control over our personal information, at worst.Such prospects are clearly far from desirable. Growing Pains Systems that can act as subtly as those described will not come without a substantial developer learning curve. As system developers learn from their mistakes, there will undoubtedly be at least one premature declaration that truly ubiqui tous computing is an impractical ideal and that the interim efforts are too riddled with problems to be usable. We cannot guarantee that ubiquitous computing will fulfill its promise. However, we would argue that it ought to do so, based on the strong trend we have observed toward more powerful, more usable software.The first author recalls a word processor from about 1984 that required the manual entry of printer codes for boldface and italic fonts. Advanced ideas like templates and styles—and, come to think of it, tables—were far from consideration as features. Modern word processors are very powerful, flexible, and easy to use compared to anything that has come before. Usability is definitely a recognized goal in software design, and much has been learned to make new software—even unique, new applications—very easy to use.It should only get better. Ongoing Research: A number of leading technological organizations are exploring pervasive computing. Xero x's Palo Alto Research Center (PARC), for example, has been working on pervasive computing applications since the 1980s. Although new technologies are emerging, the most crucial objective is not, necessarily, to develop new technologies. IBM's project Planet Blue, for example, is largely focused on finding ways to integrate existing technologies with a wireless infrastructure.Carnegie Mellon University's Human Computer Interaction Institute (HCII) is working on similar research in their Project Aura, whose stated goal is â€Å"to provide each user with an invisible halo of computing and information services that persists regardless of location. † The Massachusetts Institute of Technology (MIT) has a project called Oxygen. MIT named their project after that substance because they envision a future of ubiquitous computing devices as freely available and easily accessible as oxygen is today.What is this next generation going to look like? Today the uses of Internet are limited a s its users look for read-mostly information. As we move to a world where the Internet is used as an infrastructure for embedded computing, all this will change. We can hypothesize that the individual utility of mobile communication, wireless appliances and the respective mobile services – pervasive technologies in general – will be exploited through a digital environment that is – †¢ aware of their presence sensitive, adaptive and responsive to their needs, habits and emotions †¢ and ubiquitously accessible via natural interaction. Increasingly, many of the chips around us will sense their environment in rudimentary but effective ways. For Example – ? Cell phones will ask the landline phone what its telephone number is and will forward our calls to it. ? Remote computers will monitor our health statistics and will determine when one is in trouble and will take appropriate action for rescue. Amplifiers will be implanted and used in the inner ear . ? New machines that scan, probe, penetrate and enhance our bodies will be used. ? Refrigerators will be connected to the Internet so one could find out, via cell phone or PDA, what is in it while one is at the store. A refrigerator may even sense when it is low on milk and order more directly from the supplier or rather than this, the connection will enable the manufacturer to monitor the appliance directly to ensure that it is working correctly and inform the owner when it is not. Stoves will conspire with the refrigerators to decide what recipe makes the best use of the available ingredients, and then guide us through preparation of the recipe with the aid of a network-connected food processor and blender. Or they will communicate to optimize the energy usage in our households. ? Cars will use the Internet to find an open parking space or the nearest vegetarian restaurant for their owners or to allow the manufacturer to diagnose problems before they happen, and either inform the owner of the needed service or automatically install the necessary (software) repair. Wrist watches will monitor our sugar. [pic] ? Digi-tickers or implanted heart monitors in heart patients will talk wirelssly to computers, which will be trained to keep an eye open for abnormalities. [pic] In a nutshell, our personal network will travel around with us like a surrounding bubble, connecting to the environment through which we move and allowing our mobile tools to provide us with more functionality than they ever could alone. Conclusion: Pervasive computing provides an attractive vision for the future of computing.Well, we no longer will be sitting down in front of a PC to get access to information. In this wireless world we will have instant access to the information and services that we will want to access with devices, such as Smartphones, PDAs, set-top boxes, embedded intelligence in your automobile and others, all linked to the network, allowing us to connect anytime, anywhere s eamlessly, and very importantly, transparently.

West Africa during the Nineteenth Century - 1563 Words

The Atlantic slave trade was abolished by the British parliament in 1807. This caused great problems for West African slave traders who had witnessed a period of vast growth in the industry towards the end of the eighteenth century. They now had to focus on more lawful, legitimate means of trading. The types of industry that often replaced the slave trade were produce based, agricultural goods such as palm oil. The potential problems faced by traders were ‘exacerbated by the fact that it coincided with other problems for West Africa’s external trade.’ This refers to the Anglo-French wars which made the demand for West African exports very unreliable. The rise of the palm oil industry however, softened the blow for West Africa. Prior to†¦show more content†¦This crisis was worsened by the characteristics of the industries that replaced the slave trade. As the slave trade ‘had been effectively monopolised by a small number of large entrepreneurs†™ , the owners could benefit from economies of scale (a lower average cost caused by high levels of production). The agricultural trade had fewer barriers to entry which led to it often being produced on a small scale and was therefore much less profitable. Those that had risen to power during the slave trade period now found themselves facing a ‘high degree of atomistic competition.’ The crisis can be seen then, in the great decline in profit made by the slave owners in Western Africa. This point can be contested strongly but to do so, one must ask to whom this ‘crisis of adaptation’ applied to. Hopkins states that due to the barriers to entry in the new legitimate, produce based trade being so low, they allowed ‘the ordinary African farmer [to] enter the overseas exchange economy for the first time.’ The fact that the once prosperous and untouchable slave traders now had to compete in a competitive market does not necessarily mean that th ere was a ‘crisis’. Instead, it suggests a smooth transition from the once monopolised slave trade to a moreShow MoreRelated West African Kingdoms Essay example984 Words   |  4 PagesWest African Kingdoms It is generally accepted by scholars and scientists today that Africa is the original home of man.

Essay on Fathers of the Military - 776 Words

In the military they prepare their men to be the best they can be for the obstacles they might face when being deployed, or any other orders they might receive. But no one prepared them for being separated from their loved ones. Almost half the men who are deployed and serving our country are married and a little less than half are married and half children (insert citation-demographics chart).So what does it mean for these men? Does it make them a bad parent because they are deployed, or does it just mean they don’t get to be involved in their child’s life in the typical fashion such as seeing them every day, asking them how their day was, missing holidays and birthdays and the big moments in their children’s lives and so on.

Now that the deployment has happened, it means a new way of life for the family back at home, especially when it comes to parenting. There’s parenting from the home front as well as parenting from the war zone, each holding different types of challenges for both parents, but the focus here is the fathers at war and yet still manage to parent from home. It’s still unknown about how deployed fathers react when away from home due to not security issues but as well as communication isn’t always available depending on the location. Most fathers stated that if their partner back at home wasn’t cooperative and willing to help co-parent from a far, that it was very difficult and the already difficult task of focusing was made harder, which increased stress and anxiety in the field. As well as co-parenting, deployed soldiers have to rely on others to be able to communicate to their children back home, especially if the child is younger and can’t communicate on their own; it can create more of a space between the father and child.

The documentary The Waiting Room, is about a safety-net hospital called Highland Hospital located in Oakland, California. In the film, director Peter Nix follows patients, doctors, and staff all throughout a typical day at the hospital. Furthermore, the film displays how the staff is overworked, and how the American health care system is affecting millions of uninsured patients who try to cope with injury and disease. The film utilizes techniques from the observational mode like: long takes, crisis structure, and everyday experiences that unfold spontaneously to transmit the cruel realities of uninsured patients who go to Highland Hospital seeking hope and treatment. The Waiting Room, incorporates the observational mode trait of long takes to illustrate the chaos that occurs in the waiting room and behind the scenes of the hospital. Furthermore, the long takes in the film provide a bit of each patients’ background story and allow patients to express instead of revealing character individuality. Which can help infer why the health care system in American is failing. The long takes help uncover, â€Å"The body language, and eye contact, the intonation and tone of the voices, the pauses and â€Å"empty† time that gives the encounter the sense of concrete, lived reality† (Nicholas 176), which depicts each patients’ harsh reality of living with no health insurance.

Every time there is a buyer, the seller still writes everything from recording sales to receipts. Monthly inventory were based on sales recorded in every transactions. Inventory takes a lot time to discern the result because recorded transactions need to be reviewed first since sometimes error cannot be avoided. The manual system consumes a lot of time and it is laborious for the cashier. . 5 Current Data Flow Diagram Items’ Details Receipt 0 Manual POS Verification of Transaction Client Cashier Bill’s Information Items to be purchased Fig. 2. 0 Context Data Flow Diagram of the Current System This illustrates the Data Flow Diagram of the Walk-in/Order Transaction of the Current System.

Transaction starts when the customer enters the shop. As he/she chooses a product it will go through the cashier. Product will be first verified while the cashier writes everything into a ledger and receipt. Bills will be calculated manually or calculator will be used.

The cycle shows how the transaction works out on proposed system. As the customer enter the store he/she will choose from the products then it will pass through the cashier were the sales happen. Sales include the inputting of data, calculating and payment of bills which all happens on the system. Printed receipt and product/s will be given afterwards but for the order transaction products will be delivered or fetch on the agreed date. 1. 0 Sales Product Information Product Client Cashier 1. 3 Payment of bills 1. 1 Verification of Product Account Details 2. 0 Issuance of Receipt Receipt and product/s Purchased Bills’ Information 1. 2 Calculating of bills Bill/Payment Fig. 6. 0 First Explosion Data Flow Diagram of Walk-in Transaction of the Propose System. This illustrates the detailed Data Flow Diagram of Walk-in Transaction of the Proposed System. On proposed system everything will be easy and faster because all you/cashier have to do is to input data into the system and the system works everything for you/cashier. As the customer chooses a product/s, cashier input the date and quantity, he/she chooses on the product list price automatically appear, system calculates the total amount and receipt will be printed out. Then product and receipt will be given to the customer.

Walk-in and order transaction is almost the same. First is that the customer chooses from the list of product and gives added information or requests while the cashier input those data into the system. System will calculate everything for the cashier and as the customer pays the bill, customer will just wait for the delivery of the purchased products on the date agreed.

This chapter includes the summary, conclusion and recommendation. The summary discusses the reasons why the programmer proposed the Point of Sales system. The conclusion tells the output of the proposed system and the recommendation involves the idea or the suggestions of the programmer. 7. 1 Summary of Findings In proposing the system, the programmer makes sure that the system proposes would be a big help for the LNKS to solve the problem and to be more competitive. The programmer proposed the system to change the current system and remove the problem that the manual system produced. LNKS needs POS system to make the transactions easy and faster, to be more efficient and to avoid loss of documents and incorrect manual list. But before that, the programmer had undergone in the process of observation, data gathering and analysis to think what is the best to provide improvement for the LNKS, the programmer had an idea to propose a POS system for the LNKS. As the first problem states that manual transaction consumes a lot of time because of writing, so POS could make it faster through inputting data directly in the computer. Second problem is the storage where ledger is used and it could be lost or misplaced but it could be saved by POS because of its back up storage with security measures. And the last one is having unreliable result of inventory based on ledger; it could be because of unreadable penmanship or overlook of data, to have an accurate result POS enter where it has an automatic calculation of sold/unsold products and sales report whenever the company needs it. 7. 2 Conclusions The programmer concludes that the POS system is more professional
