WORK ANALYSIS DEVICE, WORK ANALYSIS METHOD, PROGRAM AND INFORMATION STORAGE MEDIUM

A linkage between work for setting delimitation of motions and work for setting attribute information for the motions is improved. A work analysis device 10 includes a video image data acquisition unit 110 that acquires a video image obtained by imaging a series of motions performed by a worker, a delimitation operation reception unit 131 that receives a delimitation operation for setting a motion delimitation in the video image, a selection screen display control unit 122 that executes a process for displaying a selection screen for selecting attribute information to be associated with a video image range delimited by the delimitation operation at a timing when the delimitation operation is received by the delimitation operation reception unit 131, and a storage control unit 140 that stores the attribute information selected through the selection screen in association with the video image range.
