A Good View Geometric definition of the good view region w. We would like to maximize the following criterion.
History of videotelephony In a pioneering paper, the U. In his science fiction short story " Waldo "Heinlein first proposed a primitive telepresence master-slave manipulator system. The Brother Assassin, written by Fred Saberhagen inintroduced the complete concept for a telepresence master-slave humanoid system.
In the Tele immersion, the concept is described as follows: As the control of its movements passed over to him, the slave started gradually to lean to one side, and he moved its foot to maintain balance as naturally as he moved his own. The system included stereoscopic image display from the remote environment as well as immersive touch feedback using a full upper-body exoskeleton.
Their idea was to develop a technology that would allow businesspeople to attend their meetings without leaving the resorts so that they could lengthen their hotel stays.
A Tandberg E20 high resolution videoconferencing phone meant to replace conventional desktop phones Hilton Hotels had originally licensed to install them in their hotels throughout the United States and other countries, but use was low.
The idea lost momentum, with Hilton eventually backing out. TeleSuite later began to focus less on the hospitality industry and more on business-oriented telepresence systems.
Destiny Conferencing licensed its patent portfolio to HP which became the first large company to join the telepresence industry, soon followed by others such as Cisco and Polycom. An important research project in telepresence began in Its final report stated that it " The OTP, which ended in Decemberwas part of the International Telepresence Project which linked Ontario researchers to their counterparts in four European nations.
This brings enormous time and cost benefits. It is also superior to phone conferencing except Tele immersion costas the visual aspect greatly enhances communications, allowing for perceptions of facial expressions and other body language. Mobile collaboration systems combine the use of video, audio and on-screen drawing capabilities using newest generation hand-held mobile devices to enable multi-party conferencing in real-time, independent of location.
Benefits include cost-efficiencies resulting from accelerated problem resolution, reductions in downtimes and travel, improvements in customer service and increased productivity.
Someone experiencing video telepresence would therefore be able to behave, and receive stimuli, as though part of a meeting at the remote site. The aforementioned would result in interactive participation of group activities that would bring benefits to a wide range of users.
Vision and sound[ edit ] A minimum system usually includes visual feedback. In this way, it differs from television or cinemawhere 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. This is important to prevent unintended motion sickness.
Another source of future improvement to telepresence displays, compared by some to hologramsis a projected display technology featuring life-sized imagery. Very high-fidelity sound equipment has also been available for a considerable period of time, with stereophonic sound being more convincing than monaural sound.
Manipulation[ edit ] Monty, a telemanipulation prototype from Anybots The ability to manipulate a remote object or environment is an important aspect for some telepresence users, and can be implemented in large number of ways depending on the needs of the user.
A robot in the remote location then copies those movements as closely as possible. This ability is also known as teleoperation. The more closely the robot re-creates the form factor of the human hand, the greater the sense of telepresence.
Complexity of robotic effectors varies greatly, from simple one axis grippers, to fully anthropomorphic robot hands. Freedom of movement[ edit ] iRobot Avaan autonomous roaming telepresence robot. The prevalence of high quality video conferencing using mobile devices, tablets and portable computers has enabled a drastic growth in telepresence robots to help give a better sense of remote physical presence for communication and collaboration in the office, home or school when one cannot be there in person.
The robot avatar can move or look around at the command of the remote person. Drivable telepresence robots — typically contain a display integrated or separate phone or tablet mounted on a roaming base.
The robots can map out the space and be able to avoid obstacles while driving themselves between rooms and their docking stations. Research has noted that telepresence solutions differ in degree of implementation, from "immersive" through "adaptive" to "lite" solutions.
Adaptive telepresence solutions may use the same technology, but the environments at both ends are not highly controlled and hence often differ.
Adaptive solutions differ from telepresence lite solutions not in terms of control of environments, but in terms of integration of technology.
Adaptive solutions use a managed service, whereas telepresence lite solutions use components that someone must integrate. These cues include life—size participants, fluid motion, accurate flesh tones and the appearance of true eye contact.
The chief executive officer of Cisco SystemsJohn Chambers in June at the Networkers Conference compared telepresence to teleporting from Star Trekand said that he saw the technology as a potential billion dollar market for Cisco.Teleimmersion technology allows geographically distributed users to communicate and interact in real-time through a shared virtual environment.
Users are captured by a set of stereo (depth) cameras which digitize the user into a cloud of points or a 3D mesh which .
Tele-immersion technology utilizes arrays of cameras and microphones to capture 3D scenes in real time. By having this setup at multiple remote sites and streaming the 3D data between the various locations one can provide users with a level of interaction currently not attainable by conventional 2D systems.
