Abstract
Up to now, Communication aid systems which use biosignals for physically handicapped have been proposing. On the other hand, In the field of virtual reality, man-machine interface which use biosignals is being watched with keenest interest. This paper described the analysis and discrimination method of intentions using MRCP.<br>The evoked potentials called MRCP(movement-related cortical potentials) are evoked when a man move with intention. Especially, RP (readiness potentials) that locate just before movement are not evoked without intention. So it thinkable that RPs are reflected peculiarly in the readiness. We approach RPs. We study that measure MRCPs in playing JANKEN and analyze frequency in the RPs. We study that do principal analysis in GU, CHOKI and PA. We built JANKEN discrimination model.<br>As a result, We found principal factors in 4Hz and 8Hz frequency spectrum. The discrimination system of JANKEN which built from the principal factors discriminated GU 62.5%, CHOKI 50.0% and PA 75.0% in unknown RP data. We analyzed the relations between movement forms and RP. And suggested potentials of building the 3mode intention communication system.
