Abstract: A work management apparatus includes a first detecting unit, a second detecting unit, a third detecting unit, and an information acquiring unit. The first detecting unit detects that work was executed in a work area. The second detecting unit detects that the work in the work area ended. The third detecting unit detects that a hand of an operator entered an article area where an article relating to the work is placed. The information acquiring unit acquires information relating to the work in the work area if, from when the third detecting unit detects that the hand of the operator entered the article area until when the second detecting unit detects that the work in the work area ended, the first detecting unit detects that the work was executed in the work area.

Abstract: According to one embodiment, an information processing device for a gesture-based ordering taking system or the like includes a processor. The processor is configured to detect a person making a particular gesture in image data from a camera, identify each person making the particular gesture in the image data as a first type person, then identify each first type person meeting a candidate condition in the image data as a candidate. The processor then designates a candidate as a subject according to a subject selection condition, and then detects gestured-based input from the subject in additional image data from the camera after the subject has been designated.
