Abstract: A task assistance system includes: a location detection unit (101) for setting a sensing plane in a first face side of a display means capable of displaying a plurality of articles and calculating location information of a hand located on the sensing plane or location information of an object different from the hand; a region setting unit (102) for setting a plurality of sensing regions on the sensing plane using the location information of the hand or the location information of the object calculated by the location detection unit (101); and a pass-through region determination unit (104) for determining which one of the plurality of sensing regions a hand extended to the display means from the first face side has passed through using the location information of the hand calculated by the location detection unit (101), after the region setting unit (102) sets the plurality of sensing regions.

Abstract: An imaging unit (210) images a front side of a disposition unit (300). A distance measuring unit (220) calculates a distance (for example, a distance in a Y direction in FIG. 1) from the distance measuring unit (220) to a hand positioned in front of the disposition unit (300). A work support apparatus (100) analyzes image data obtained by the imaging of the imaging unit (210), and calculates the position of the hand in a direction (for example, in an X direction in FIG. 1) that is across a straight line that connects the disposition unit (300) and the imaging unit (210). Further, the work support apparatus (100) specifies a disposition area (310) to which the hand extends based on the analysis result of the image data and the measurement result of the distance measuring unit (220).
