Mental Reaction and Medical Application in the Shared Surrounding with Mixed Reality under Giant Environment

We have developed a realtime Pathos quantification system for the trial operation of multi-screen display ( UNIVERS type ). The items of examined data were pulse rate, respiratory rate, sweating, EEG with ICA, and light reflex. The video contents were taken such land scope at Mt. Fuji, costal scenery, driving scenery, virtual town, mixed realty with poem and sky view.Results: When the candidate operated and faced to some critical situation under the flight simulator, the data of sweating from skin was increased with operational stress at any time. The magnificent land scope such Mt. Fuji shows relaxation with alfa wave on EEG.The light reflex was also effective to detect pathos, however, there was no remarkable difference of pupil's speed with direct between NTSC TV system and multi-screen system(UNIVERS). The sweating from skin was 100% reflect of mental stress at realtime, and it will be very important parameter of pathos. Mental sweating has a difference between NTSC TV system and multi-screen system(UNIVERS) and it might be very useful to understand the wideness of screen in size.We tried to link with broadband network and connected two UNIVERS system, and tested mental sweating that suggested it will be suggested synchronization of pathos.
