What is a “Wearable Computer”
Wearable computers are small portable computer that is designed to be worn on the body during use.
Always on, always ready, always accessible
In this, wearable computers differ from PDAs, 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 Computers
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.
It is 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.
Operational Modes
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.
Augmentation: Traditional computing paradigms are based on the notion that computing is the primary task. Wearable computing, however, 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 It doesn't necessarily need to completely enclose us, but the concept allows for a greater degree of encapsulation than traditional portable computers.
Ideal attributes
Persist and provide constant access to information services.
Everyday and continuous use.
Wearable can interact with the user at any given time.
The user can access the wearable quickly and with little effort.
Sense and model context.
The wearable must observe and model the user’s environment, physical and mental state.
The user could provide explicit contextual cue to the wearable.
The user can identify misunderstanding and explicitly tutor the wearable.
