 A small portable computer that is designed to be worn on the body during use.  In this, wearable computers differ from PDAs (personal digital assistant), which are designed for hand-held use.  Wearable computers are usually either integrated into the user's clothing or can be attached to the body through some other means, like a wristband.  They may also be integrated into everyday objects that are constantly worn on the body, like a wrist watch or a hands-free cell phone.

 Wearable Technology is a portable computer that is included into the space of a user, this can be worn anywhere around the body and can be hands free use.  Particularly it is a device that is always with the user, the user is able to enter commands and execute a set of entered commands while the user is walking around or doing any other activity.

 To develop new interfaces that modify non- computer activities.  Without interfering with the user’s everyday tasks.  The design of wearable computers is still a topic of research & a variety of user interfaces are being proposed.

 Wearable Computers were first introduced in the 1500's with the pocket watch.  In 1967, Hubert Upton developed a technology which allowed the person wearing the glasses to lip read, this was using the LED device.  Even in the 1980's and the 1990's wearable computers were being created.

 Some wearable computers use “keyers” (key switches mounted to a grip, rather than to a board, as with a keyboard) and trackballs as input device.  Many try to use more intangible means of input like gesture, speech recognition or context awareness.  The output may be presented through displays, lights, sound or even haptic interfaces(touch screen).  Some mediated reality (ability to modified reality) systems can also be considered wearable computers.

W.C. in the MEDICAL FIELD

5 categories of performers:  1) Entertainers  2) Animators  3) Provocateurs  4) Communicators  5) Performance Artists Examples:  Water turned into fire  Simple objects become dangerous  Mime(multipurpose internet mail extension) wearing small wearable computer in pack pack  Flat panel display is connected for audience to use

Pros n cons  The advantages of Wearable Computers are:- - Enhanced Communication - Able to use wearable computers to complete daily tasks such as a computer which tracks the movements and habits of a person. - Flexibility - Freedom - Work from anywhere - Convenience  The disadvantages of Wearable Computers:- - Equipment can be heavy, Expensive - Some Wearable Computers can consist of a lot of wiring - Can cause irritation in heat, Side-Effects such as Headaches - Can be used to gain an unfair advantage over others - It may become easier to get data on an individual if the item is lost/stolen

Future of wearable computers  Wearable Computers would dominate in the near future.  Years ago you would not have thought that you could do somethings that you can do today as computers are getting smaller and more powerful they can be integrated into virtually anything.  Now you can class your mobile phone as a mobile computer as that can be used take photos, surf internet, and many other things.  We believe that all electronic devices will be able to communicate with each other. and recognize who you are similar to minority report where eyes are scanned to welcome a person instead of scanning your eyes it will be scanning any electronic devices that you may be carrying, this would bring in to the picture security.

The use of mobile and wearable computers as actual “tools” on the construction site will enable interaction with smart infrastructure systems in the future. But to reach this goal, we face some challenges that have to be solved.
