Virtual and telepresence systems are applications, in which a human operator is present in a remote environment with his subjective perception by means of technical mediums. A teleoperator, in most cases a robot, takes orders from the operator. These orders are assigned via a bi-lateral communication channel. Several components can have an impact on human task performance and his feeling of presence. Examining personality traits and states, it was shown that practice took effect on both task performance and feeling of presence, however, adaptability, directing attention to the task in the remote environment and inducing high involvement had only an impact on task performance, but not on feeling of presence. The quantization and compression of data assigned via the communication channel below the just noticeable difference had no detrimental effects on task performance and feeling of presence. Delays above 150 to 200 ms caused strong impairments of task performance and feeling of presence. Regarding the feedback of information from the remote environment, positive effects could be found for widening the field of view and good three-dimensional visual presentation, but breaks in visual presentation should be avoided. For manipulation tasks, beneficial effects on task performance and feeling of telepresence showed up when comprising all manipulational degrees of freedom to the human operator. No direct relationship was found between task performance and feeling of presence.
