  • Patent number: 11651317
    Abstract: A work operation analysis system 11 includes: a deviant operation analysis unit 114 that analyzes a work video obtained by photographing work of a worker on a work process basis and, in the case where a deviant operation different from normal work has been detected, identifies the occurrence timing of the deviant operation; a work video accumulation unit (a normal work video accumulation unit 117 and a deviant work video accumulation unit 118) that accumulates a normal work video obtained by preliminarily photographing normal work and a deviant work video obtained when the deviant operation occurred; and a display unit (a display input device 111) that displays the normal work video and the deviant work video having predetermined time including the occurrence timing of the deviant operation.
