- A wearable computer is a computer that is subsumed into the personal space of the user, controlled by the user, and has both operational and interactional constancy, i.e. is always on and always accessible. Its a device that is always with the user, and into which the user can always enter commands and execute a set of such entered commands, and in which the user can do so while walking around or doing other activities.
- The wearable computer is more than just a wristwatch or regular eyeglasses: it has the full functionality of a computer system but in addition to being a fully featured computer, it is also inextricably intertwined with the wearer. It has been developed for general or special purpose information technologies and media development.Wearable computers are especially useful for applications that require more complex computational support than just hardware coded logics.
HistoryIn 1960s, cigarette-pack sized analog computer designed to predict roulette wheels.In 1970s, the Evolution of Steve Manns WearComp wearable computer from backpack based systems and a camera-to-tactile vest for the blind, published by C.C. Collins and in the end of 70s HP-01 algebraic calculator watch by Hewlett-Packard.In 1980s Steve Mann designed and built a backpack-mounted 6502-based computer to control flash-bulbs, cameras and other photographic systems Wearable Wireless Webcam.
- Steve Roberts built Winnebiko-II, a recumbent bicycle. Reflection Technology marketed the Private Eye head-mounted display.In 1990s, Twiddler chording keyboard made by Handykey, Edgar Matias and Mike Ruicci debuted the "wrist computer.Mik Lamming and Mike Flynn at Xerox EuroPARC, demonstrated the Forget-Me-Not.In 2000s, as part of Kevin Warwick's Project Cyborg a necklace made which was electronically linked to nervous system
A framework called Sulawesi has been designed which gives the wearable computer an ability to accept input from any number of modalities, and perform if necessary a translation to any number of modal outputs. This system that has been designed comprises of three distinct parts:Multimodal-multimedia based Input system, gathers raw data from the various sensorsAgent based core system, contains a natural language processing module and service agents Proactive and Wearable Output system, decides when and how to render the results from the service agents
There is a constant interaction between the computer and userMultitasking
Wearable Computers provide computational support even when the user hands, eyes, voice and attention is actively engaged with physical environmentMobility
Wearable computers must go where the wearer go.
Examples:Motorolla wearable pc by which one can use his/her cell phone.TwiddlerFactoid systemSixth Sense by Pranav Mistry a PhD candidate.
Advantages:PortabilityHands free useComfortableAlways on the task it is designedQuick to accessFashionable
DisadvantagesEquipment can be heavyExpensiveSome wearable computers can consist lot of wiringCan cause irritation in heatSide effects such as headache
