Wearable computer

• 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.

History

• In 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

Architecture

• 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 sensors
• Agent 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

Features

• Consistency
• There is a constant interaction between the
  computer and user
• Multitasking
• Wearable Computers provide computational support
  even when the user hands, eyes, voice and
  attention is actively engaged with physical
  environment
• Mobility
• Wearable computers must go where the wearer go.

• Examples
• Motorolla wearable pc by which one can use
  his/her cell phone.
• Twiddler
• Factoid system
• Sixth Sense by Pranav Mistry a PhD candidate.
