Abstract: A workability evaluating apparatus, comprises a myoelectric potential detecting unit, a signal processing unit, an arithmetic operation unit, an evaluation unit, and an output unit. The myoelectric potential detecting unit detects time-series fluctuations in myoelectric potentials of at least one pair of muscles, which show antagonistic activities in operating an eqipment among muscles of an operator used to operate the equipment, as myoelectric potential signals. The signal processing unit processes the detected myoelectric potentials. The arithmetic operation unit calculates time-series data of a first correlation coefficient in a specified sampling time between signals obtained by processing the myoelectric potential signals from the pair of antagonistic muscles. The evaluation unit performs evaluation of workability in operating the equipment by using the calculated time-series data of the first correlation coefficient and the output unit outputs a result of the evaluation performed by the evaluation unit.

Abstract: A stress-at-work judging apparatus, program, and method for judging the stress exerted on the subject at work such as steering of a vehicle by the subject. An myoelectric potential signal of the masseter muscle is inputted during an object work carried out by the activity of muscles independent of the activity of the masseter muscle opening/closing the jaw of the subject. The myoelectric potential signal representing a change of the activity of the masseter muscle and generated when the object work acts as a stressor of the subject is used to judge the stress. A camera or microphone is disposed near the subject to exclude the period during which the subject speaks or masticate by using the masseter muscle independently of the object work from the object period during which stress is judged.
