Telepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance that they were present, or to have an effect, at a location other than their true location. Telepresence requires that the senses of the user, or users, are provided with such stimuli as to give the feeling of being in that other location.
Additionally, the user(s) may be given the ability to affect the remote location. In this case, the user's position, movements, actions, voice, etc. may be sensed, transmitted and duplicated in the remote location to bring about this effect. Therefore information may be travelling in both directions between the user and the remote location.
TelePresence is a new technology that creates unique, "in-person" experiences between people, places, and events in their work and personal lives. It combines innovative video, audio, and interactive elements (both hardware and software) to create this experience over the network. Telepresence means "feeling like you are somewhere else". Some people have a very technical interpretation of this, where they insist that you must have head-mounted displays in order to have telepresence.
For a user to be given a convincing telepresence experience, sophisticated technologies are required. The Cisco TelePresence Meeting solution consists of the Cisco TelePresence technology, codecs, cameras, lighting arrays, microphones, speakers, and endpoints that consist of one or more 65-inch plasma screens, and in some models, one-half of a "virtual" conference table. Also included is the Cisco TelePresence Manager, which provides event management, help desk and consolidated device status reporting. It enables integration to enterprise groupware for easy scheduling and launching of Cisco TelePresence calls. Integration with Cisco Unified Communications Manager 5.1 and enterprise groupware provides Cisco TelePresence with just one button to push to launch calls directly from the phone.
Cisco TelePresence endpoints consist of two models, designed for different numbers of users and different size environments:
. Cisco TelePresence 3000 -A virtual table with seats for 6 on each side, including three 65-inch plasma screens, speakers, microphones, and lighting
. Cisco TelePresence 1000 -Designed to be flush-mounted along a wall space for easy use in smaller footprint areas (for example, individual offices, bank branches, lobbies, doctor's offices) includes one 65-inch plasma screen, speakers, a microphone, and lighting
A minimum system usually includes visual feedback . Ideally, the entire field of view of the user is filled with a view of the remote location, and the viewpoint corresponds to the movement and orientation of the user's head. In this way, it differs from television or cinema , where the viewpoint is out of the control of the viewer.In order to achieve this, the user may be provided with either a very large (or wraparound) screen, or small displays mounted directly in front of the eyes. The latter provides a particularly convincing 3D sensation. The movements of the user's head must be sensed, and the camera must mimic those movements accurately and in real time. This is important to prevent unintended motion sickness.
