Google Glass is only one of an emerging technology sector called wearable computers, also known
as body-borne computers or wearables are miniature electronic devices that are worn by the bearer
under, with or on top of clothing. This class of wearable technology has been developed for general
or special purpose information technologies and media development. Wearable computers are especially
useful for applications that require more complex computational support than just hardware coded logics.
One of the main features of a wearable computer is consistency.
There is a constant interaction between the computer and user, i.e. 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 user’s mind and/or body.
Many issues are common to the wearables as with mobile computing, ambient intelligence and
ubiquitous computing research communities, including power management and heat dissipation, software
architectures, wireless and personal area networks.
