Wearable computers are computers that are worn on the body. They have been applied to areas such as behavioral modeling, health monitoring systems, information technologies and media development. Government organizations, military, and health professionals have all incorporated wearable computers into their daily operations. Wearable computers are especially useful for applications that require computational support while the user’s hands, voice, eyes or attention are actively engaged with the physical environment.
One of the main features of a wearable computer is consistency. There is a constant interaction between the computer and user, ie. there is no need to turn the device on or off. Another feature is the ability to multi-task. It is not necessary to stop what you are doing to use the device; it is augmented into all other actions. These devices can be incorporated by the user to act like a prosthetic. It can therefore be an extension of the userâ€™s mind and/or body.
Such devices look far different from the traditional cyborg image of wearable computers, but in fact these devices are becoming more powerful and more wearable all the time. The most extensive military program in the wearables arena is the US Army’s Land Warrior system, which will eventually be merged into the Future Force Warrior system.
