Abstract: Provided are: an extraction unit extracting a plurality of sets of combinations of planes and coordinates corresponding to a plurality of objects from among images of the respective objects belonging to image information, based on the image information including the respective images of the plurality of objects which are images in a front direction of a worker; a plane selection unit selecting a designated set from among the plurality of sets of combinations of planes and coordinates extracted by the extraction unit according to a rule in which a priority for a plane corresponding to each object is defined; and an analysis unit calculating a gaze point coordinate indicating a gaze point of the worker based on visual line information indicating a visual line position of the worker and information on a combination of a plane and a coordinate belonging to the designated set selected by the plane selection unit.

Abstract: A work support apparatus holds a value indicating information on at least one of an apparatus used for a work and a worker, a work change recognition determination algorithm, and a work support content corresponding to a determination result, applies a value indicating information on at least one of the apparatus and the worker to the work change recognition determination algorithm, determines whether or not the worker recognizes a work change indicating at least one of a change in a work process and a transition between a normal state and an abnormal state of a work, and outputs, to the output device, a work support content corresponding to the determination result.
