    • INTRODUCTION A wearable computer is a small portable computer that is designed to be worn on the body during use. Wearable computers are usually either integrated into the users clothing or can be attached to the body through some other means , like a wristband. The computer evolution has moved from mainframes, to the desktop, and now the computing power is moving onto the person. The user actually "wearing" the computer, s/he can utilize the power and functionality virtually anywhere in their environment. This technology is developing and changing rapidly primarily due to vast changes in computer speed, wireless technology and miniaturization of components. 21/3/2007 3
    • Operational Modes of Wearable Computer Constancy Augmentation Mediation 21/3/2007 4
    • Xybernaut: A CurrentCommercially Available Wearable System 21/3/2007 5
    • Networking and Operating System The goal of wearable/interactive computers is to network all components through one operating system. There are two competing operating systems, Sun Microsystems Jini and Microsoft Windows CE ("Compact Edition"). Sun apparently sees all appliances /components networked through Java/Jini interface, while MS seems to be taking the more traditional personal computer interface approach in connecting appliances to the network. 21/3/2007 6 Far Field and Near field Communication.

    • Outlook of Wearable Computer 21/3/2007 11
    • Agents A premise of a wearable computer is that the computer can learn and become customized to the users needs, based upon the task the user is involved with. If the user is viewing a document, the Wearable Computer may suggest an associated email, showing minimal information such as the subject, sender, date, or what ever information the user would want to view to get a sense as to decide whether the entire email should be retrieved. Humans are poor at data retrieval, and a complex hierarchical directory quickly breaks down when the human user loses the thread of where the item being searched for resides. A computer remembrance agent can take cues from this environment to assist in locating appropriate files from memory, picking up on cues like where the user is, is the user alone or with someone , what is the user doing at that time, etc., all can be used to search and locate appropriate files that may be relevant to the user at that time. In this manner the computer is a continual presence, always looking over the shoulder of the user. For example, at a staff meeting the Wearable Computer can assist in remembering names of attendees, who was at the meeting prior, what they said at that time, what was on the agenda, and also to suggest topics which might be of relevance to what was going. The computer is always active in searching the users own personal data base for information which might prove useful within the context of the current task the user is performing. 21/3/2007 12
    • Recognizing Affect Our emotions play a significant role in our every day life, and up to now, this had been unrepresented within human computer interfaces. Human vital signs such as blood pressure , temperature, galvanic skin response, foot pressure and electromyograms can be tracked and monitored through the use of body sensors connected into the wearable computer. In this manner, the computer becomes physically connected to the user and can learn to recognize physiological states . By this monitoring of body vital signs and learning how the user reacts when in different feeling and mood states, the computer can take action accordingly. For example, if the user likes to hear a certain type of music at one time and another during a different mood state, the computer can plan on providing this to the user at the appropriate times. The affective sensors could also be of assistance in medical monitoring where important health data might be tracked and reported directly to the user’s physician. They list four bio-sensors used in a current prototype affective wearable system: measuring respiration , skin conductivity, blood volume pressure and electromyogram, all of which the sensors can monitor painlessly from the surface of the skin. These four sensors are monitored via a Linux operating system, and can be sampled up to 20 times per second. Affective computing employs its own intelligent agent which can make decisions based upon analysis of the incoming environmental and physiological sense data. 21/3/2007 13
    • Applications Smart Wallet Worker Training and Worker Support 21/3/2007 14
    • Military 21/3/2007 15
    • Handicapped 21/3/2007 16
    • Future ResearchFuture research and development issues include the following: Ergonomic research - best method to utilize components, e.g. - the head set such that it is comfortable and is helping and not distracting the user from the task. There needs to be more light weight efficient and easily powered computer apparatus which is comfortable to wear. In terms of Network using the body as the networks medium, to increase the speed at which they can run also to increase to bps speed of data transfer . 21/3/2007 17
    • ConclusionLot of research and experiments for practical & tacticaluse of Wearable Computer are going on around the world.Several types of Wearable Computer’s are indeedcommercially available, but as of now most of them aretailor made for specific applications. It is only a matter oftime before the consumer community accepts the idea. Theshift that the Wearable Computer’s will bring;computer workingalong with you instead of you working at the computer.Thoughthe wearable has not seen the widespread acceptance givento the desktop, work continues in this field to meet thechallenges that inhibit its growth. Processors and sensors needto be effectively integrated into textiles; and displays, whetherhead or body mounted, need to effective under a wide rangeof lighting conditions - all of these must be comfortable to wear 21/3/2007 18
