Introduction
A wearable computer is a computing device small and light enough to be worn on one's body without causing discomfort.
Unlike a laptop or a palmtop , wearable computer is constantly turned on and interacts with the a real-world task.
Information could be even very context sensitive.
Defination
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.
Constancy
The computer runs continuously, and is always ready to interact with the user.
Unlike a hand-held device, laptop computer, or PDA, it does not need to be opened up and turned on prior to use.
The signal flow from human to computer and computer to human, runs continuously to provide a constant user-interface.
Augmentation
Wearable computing is based on the notion that computing is not the primary task.
The assumption of wearable computing is that the user will be doing something else at the same time as doing the computing.
Thus the computer should serve to augment the intellect, or augment the senses.
Mediation
Unlike hand held devices, laptop computers, and PDAs, the wearable computer can encapsulate us.
It does not necessarily need to completely enclose us, but the concept allows for a greater degree of encapsulation than traditional portable computers.
Thanks to encapsulation, it can function as an information filter, and allow us to block out material we might not wish to experience,
Human-Interface system
The user interface for a wearable computer is fundamentally different to those of the regular computers.
The ideal human-computer interface for use in a wearable environment would be one which listens for its user, understands what the user has asked it to do as a combination of speech recognition, gestures and a bit of machine vision.
The results should be presented back to the user in an intelligent manner, when it is most appropriate and in a suitable format.
Augmented reality
Augmented Reality combines real world scenes and virtual scenes
It augments the real world with additional information.
The computer must be able to operate in the background, providing enough resources to enhance but not replace the user's primary experience of reality.
