INRTODUCTIONMost notably, it is a device that is alwayswith the user, and into which the user can always enter commands and execute aset of such entered commands, and in which the user can do so while walkingaround or doing other activities. This transformation allows it to be wornconstantly, with the goal of becoming a seamless extension of body and mind,equipped with various sensors which measure heart rate, respiration, footsteprate etc.
, and can help in body maintenance. DEFINATION OF A WEARABLE COMPUTERS· Wearable computing facilitates anew form of human-computer interaction comprising a small body-worn computerthat is always on and always ready and accessible. · A wearable computer is a computerthat is engulfed into the personal space of a user, controlled by the user, andhas both operational and interact ional constancy HISTORY ON WEARABLE COMPUTINGThe concept of wearable computing was first brought forward bySteve Mann, who, with his invention of the ‘Wear Comp’ in 1979 created apioneering effort in wearable computing. Although the effort was great, one of the major disadvantages was thefact that it was nothing more than a miniature PC. Absence of lightweight,rugged and fast processors and display devices was another drawback. The 1980sbrought forward the development of the consumer camcorder, miniature CRTs etc.
brought forward the development of the eyeglass mounted multimedia computer.With the advent of the internet and wireless networkingtechnologies, wearable devices have developeda great deal.LITRATURE REVIEW:Wearable computing facilitates a new form of human-computer interactioncomprising a small body-worn computer that is always on and always ready and accessible.
In this regard, the new computational framework differs from that ofhand held devices, laptop computers and personal digital assistants (PDAs). The”always ready” capability leads to a new form of synergy between human andcomputer, characterized by long-term adaptation through constancy ofuser-interface. APPLICATIONSThereare several aspects and affordances of wearable computing are applicable. Theyare discussed in brief below1. Smart eyeglasses: It would notappreciably obstruct the wearer’s vision, or otherwise be encumbering.
forexample, the wearer could be used to play in a competitive gamee.g.volleyball 2. Smart cards and badges: Wear Camis a simple apparatus for effortless capture, display, processing andtransmission of visual Imagery.Since the apparatus is worn on an extendedperiod of time, one adapts to it, and it begins to function as a true extensionof body.3. Military application: The smart shirt wasbeing designed for soldiers in combat, so that medical personnel could find theexact location of a bullet wound. ADVANTAGES DISADVANTAGES 1.
Portability Equipment can be heavy 2. Hands-free use Quick to access 3. Comfortable Some Wearable Computers can consist of a lot of wiring.
4. Always on for the task it is designed Can cause irritation in heat 5. Quick to access Side-Effects such as Headaches. CONCLUSIONWearable Computers willhelp in the development of a cyborg a system in which the camaraderie between ahuman and machine becomes seamlessly simple.
This will bring forward a new setof technical, scientific and social needs which will have to be addressed as wetake the first step towards coexisting with wearable computers REFRENCES www.media.mit.edu/wearables,www.redwoodhouse.com/wearable www.wearcam.org/personaltechnologies ,www.wesrcomp.org/wearcompdif.
