A coordinate reception unit receives time series spatial coordinates of an object to be detected. The spatial coordinates include a coordinate in a first direction, a coordinate in a second direction intersecting the first direction, and a coordinate in a third direction intersecting the first direction and the second direction. When a predetermined first condition related to a change in the coordinate in the first direction is satisfied at a first point of time and then a predetermined second condition related to a change in the coordinate in the first direction is satisfied at a second point of time, a function execution unit executes a process in electronic equipment that is a target of control, based on the coordinate in the second direction and the coordinate in the third direction at one or more points of time between the first point of time and the second point of time.
