Abstract: A work comfort evaluating device is a device for evaluating a level of comfort of work by measuring myoelectric potentials of plural muscles when the work is done by antagonistic activities of the muscles. The device has a pair of detecting sensors, an amplifier, a signal processing part, a work-load intensity calculating part, and an evaluation part. The sensors sense myoelectric potentials of the muscles at a time of the work. The signal processing part calculates a synchronous contraction intensity of the muscles by using myoelectric potential waveforms. The work-load intensity calculating part calculates a level of a work load intensity in the work. The evaluation part evaluates a level of comfort of the work by normalizing the synchronous contraction intensity by the level of the work load intensity calculated.

Abstract: A work pleasantness evaluating device and method for evaluating the pleasantness of a work of any type such as steering of a vehicle by a driver. Myogenic potentials of a pair of muscles symmetrically present in a human body, produced by a myogenic activity of the human body during a work are measured and amplified. From the time-series waveforms of the pair of the amplified myogenic potentials, a synchronous contraction waveform of the pair of muscles is generated. From the information on the intensity of the generated synchronous contraction waveform or the information on the frequency at a predetermined intensity range, the level of the pleasantness of the work is evaluated. The synchronous contraction waveform is generated such that, for example, the time-series waveforms of the pair of myogenic potentials are full-wave rectified, and the rectified time-series waveform having the smaller signal value out of the rectified time-series waveforms at the same time is used as the synchronous contraction waveform.

Abstract: A stress-at-work evaluating device evaluates a stress of a subject at work by measuring activities of one of the right and the left masseter muscles, the work including exercise of arms or feet of the subject. The device evaluates the stress from a normalized intensity of the myoelectric potential one of the right and the left masseter muscles. The normalized intensity is calculated by dividing the intensity of the measured myoelectric potential of the masseter muscles by the level of the external force acting on the head of the subject at work.

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: Different loads are applied to the skeletal muscle of at least one of an upper arm, an upper limb girdle, and a lower limb of the test subject to cause isometric muscle contraction under each load and measure the muscle activity of the skeletal muscle. Then, an upper limit of the muscle activity in a region where a magnitude of the load and an intensity of the muscle activity have a linear relationship is determined as the limit in an appropriate muscle activity range that suits the test subject. Subsequently, the muscle activity of the skeletal muscle of a test subject operating an instrument is measured, and the test subject's force for operating the instrument is evaluated based on a frequency distribution where the frequency of the muscle activity of the skeletal muscle being exercised to operate the instrument is distributed with respect to the obtained limit.
