Telexistence is a concept that enables us to overcome the limitations of time and space by mutual presentation of a feeling of existence in a virtual sense. By using telexistence technology based on this concept, even if users are far apart from each other, they can meet and talk as if they share the same space and time. This is the goal of the development of the mutual telexistence communication systems as a natural extension of the telephone to the telexistence-videophone. In this paper, three types of telexistence communication systems are proposed for development, i.e., the telexistence communication booth for public facilities/offices, the telexistence-videophone for home use, and the wearable telexistence-videophone for personal use.
