Patent ID: 7693572

Claim:
A workability evaluating apparatus, comprising: a myoelectric potential detecting unit for detecting time-series fluctuations in myoelectric potentials of at least one pair of antagonistic muscles, which show antagonistic activities while operating equipment among muscles of an operator used to operate the equipment, as myoelectric potential signals; a signal processing unit for processing the detected myoelectric potentials to obtain processed myoelectric potential signals of respective antagonistic muscles in said at least one pair of antagonistic muscles; an arithmetic operation unit for calculating time-series data of a first correlation coefficient in a specified sampling time by calculating said first correlation coefficient between two signal values at each time in said processed myoelectric potential signals obtained by processing the myoelectric potential signals from the at least one pair of antagonistic muscles, and for performing evaluation of workability in operating the equipment by using values of the calculated time-series data of the first correlation coefficient, wherein the workability is an index for indicating operability when the operator operates the equipment; and an output unit for outputting a result of the evaluation performed by said arithmetic operation unit.
