computer to human, runs continuously to computer to human, runs continuously to provide a constant user interface (provide a constant user interface (figure 1figure 1). ).

Augmentation:Augmentation:wearable computing is based on the notion wearable computing is based on the notion
that computing is that computing is NOTNOT the primary task. the primary task. assumption: assumption:
the user will be doing something else at the same the user will be doing something else at the same time as doing the computing and the computer time as doing the computing and the computer should serve to augment the intellect, or augment should serve to augment the intellect, or augment the senses (the senses (figure 2figure 2). ).

Mediation (cont…):Mediation (cont…):To make the signal flow more explicit, the To make the signal flow more explicit, the
computer and human are depicted as two computer and human are depicted as two separate entities within an optional protective separate entities within an optional protective shell, which may be removed or partially shell, which may be removed or partially removed if a mixture of augmented and removed if a mixture of augmented and mediated interaction is desired (mediated interaction is desired (figure 4figure 4). ).

Wearable computing is a framework for enabling Wearable computing is a framework for enabling various degrees of each of these three various degrees of each of these three fundamental modes of operation.fundamental modes of operation.
The space of possible signal flows giving rise to The space of possible signal flows giving rise to this entire space of possibilities (this entire space of possibilities (figure 5figure 5).).
The signal paths typically each, in fact, include The signal paths typically each, in fact, include multiple signals, hence multiple parallel signal multiple signals, hence multiple parallel signal paths are depicted in paths are depicted in figure 5 figure 5 to make this to make this plurality of signals explicit. plurality of signals explicit.
