People wanted to have their computer with them at all times to use at a moment's notice. It is not surprising then, that most people still think of computers as just big blocks of iron which are either attached to a desk or need to be plunked down upon one before work can begin. For more than twenty years though, there have been visionaries who refused to see these computers just as big blocks of iron sitting on our desks. They were after a new paradigm of computing - computers that would be the extension of one's personality, computers that would work with your body rather than against it, and almost needless to say, the computers that will be with you at all times, always at your disposal. In the two decades that had passed, wearable computing pioneers and the growing army of followers had had more than enough time to think through the shortcomings of their invetion.
Wearables are at their prime.
Alongside with the new concepts in design came the new concepts in philosophy and applications. One of the prevalent ideas in wearable computing is the concept of mediated reality . Mediated reality refers to encapsulation of the user's senses by incorporating the computer with the user's perceptive mechanisms which are used to process the outside stimuli. For example, one can mediate their vision by applying a computer controlled camera to enhance it. A subset of mediated reality is augmented reality.
