Humans’ primitive skill of imitative learning is regarded as an origin of human intelligence because it is said that imitation is fundamental function for communication and symbol manipulation. M.Donald has proposed “mimesis model” in order to approach to a symbol emergence framework from behavior recognition/generation for humanoid robots. In this paper, we propose a mathematical model for motion recognition and generation as combination of basic motions by proto-symbol manipulation which is abstract expression of motion patterns. In order to describe the proto-symbol manipulation as geometric manipulation, construction of proto-symbol space and geometric proto-symbol manipulation method are established.
