Wearable computers make possible useful deployment of technology in situations and environments which were previously impervious to technology.For instance, assembly and repair personnel often need to keep both hands free to perform a given task.

Immobile computers, such as desktops, are of little value in such environments, and portable solutions, such as laptop and handheld computers, are little better.Wearable computers, on the other hand, are ideally suited for such settings, since they provide most if not all of the data processing functionality offered by other solutions and yet are also fully hands-free and mobileA current personal imaging apparatus, based on a camera and display built within an ordinary pair of sunglasses, together with a powerful multimedia computer built into ordinary clothing, points to a new possibility for the mass-market.
