Telepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance of being present, or to have an effect, via telerobotics, at a place other than their true location.
Telepresence requires that the user senses be provided, to give the feeling of being in that other location. Users may be given the ability to affect the remote location. The user’s position, movements, actions, voice, etc. may be sensed, transmitted and duplicated in the remote location. The information will be travelling in both directions between the user and the remote location.
Applications of telepresence include working in extreme heat or cold, high or low pressure, and in other conditions hazardous to human life. Telepresence might be used to disarm bombs, handle toxic materials, and conduct dangerous military missions. Telepresence has been suggested as a method of performing surgery by remote control, and as a method of performing nanoscale operations by scaling down the telechir by a factor of thousands or millions.
