Multimodal Telepresence and Teleaction

Telepresence, Haptic and Networked-Control Systems

"Telepresence has been defined by Prof. Thomas B. Sheridan in 1992 as a system in which the human operator receives "sufficient information about the teleoperator and the task environment, displayed in a sufficiently natural way, that the operator feels physically present at the remote site". Hence a telepresence system enables a human operator to perceive and manipulate a remote environment.

A telepresence system consists of three components. The human system interface (HSI) is handled by the human operator. He/She commands the teleoperator to perform actions in a remote environment. HSI and teleoperator exchange command and feedback signals over a communication line.

To achieve a holistic remote immersion, multiple modes of human perception are addressed including haptic, visual, and auditory senses. The level of the immersion is called the transparency of the telepresence system. To reach this goal telepresence conglomerates three disciplines: robotics, telecommunications and virtual reality.

Intended applications for telepresence systems are telesurgery, teleassembly and teleservice systems. In hazardous environments, for example, multimodal telepresence will provide significant benefits. As illustrated in the figure below search-and-rescue operations could be done by a tele-commanded robot reducing risks and increasing efficiency." Continue reading >>
