Five senses theatre project: Sharing experiences through bodily ultra-reality

The Five Senses Theatre project was established for the development of a basic technology that enables the user to relive a spatial motion of other persons as if the user him/her-self experienced it in person. This technology aims to duplicate a bodily experience performed in the real space and to pass it to the other person. In other words, the user experiences another person´s body that moved in a real space as if the user moved in that real space. The spatial motion may be a walking tour to the world heritage, a legend run of a top athlete, and etc. More specifically, the system creates the sensation of a self-body motion without a voluntary motion of the user by providing physical motion to the real body. The sensation of self-body motion is generated by not only a visually induced vection but proprioceptive and tactile sensations of the body passively evoked. The Five Senses Theatre provides multisensory stimuli to the user to make use of the user´s body as medium to project the valuable experience from others to the user´s cognition. The research issues include the following: 1) Cognitive mechanism of passive stimulation perceived as an active motion sensation (pseudo agency), and body ownership transfer (virtual body). 2) Device development of the mutisensory display system, rendering/projection algorithms, and a lifelog data system.
