Abstract
A physical motion state evaluation apparatus is configured by a foot switch unit for detecting user's step motions, physical motion state detectors for detecting motions of prescribed parts (e.g., hands, foot) of a user's body, a display and a musical tone generator. Herein, the physical motion state detector is configured by a projector unit for projecting optical beams along optical axes and a receiver unit for receiving the optical beams respectively, so that the receiver unit detects a shutoff event in which the prescribed part of the user's body shuts off at least one of the optical beams. Physical motion state instructions request a user to move the prescribed parts of the user's body to instructed positions at instruction timings respectively, so that the physical motion state detectors provide detection timings at which the prescribed parts of the user's body are precisely moved to the instructed positions in conformity with the instruction timings. Based on deviation values between the instruction timings and detection timings, the apparatus produces evaluation results on user's physical motion states in comparison with the physical motion state instructions. The evaluation results can be visually presented on a screen of the display as scores being marked for the user's physical motion states, or they can be subjected to auditory presentation in which the musical tone generator sequentially generates musical tones corresponding to constituent notes of a melody in response to the detection timings that belong to tone generation ranges of the instruction timings.
