1. An information processing apparatus for obtaining instruction content data describing content of a user instruction and for carrying out information processing based on the instruction content data, comprising: a distance distribution image obtaining unit configured to obtain a distance distribution image produced based on a measured result output from a distance distribution measuring unit configured to measure a distance distribution from the information processing apparatus to an object of a user within a predetermined view field, the distance distribution image showing the distance distribution; an instruction content data producing unit configured to produce the instruction content data, based on the distance distribution image, where only one or more portions of the distance distribution image corresponding to distances between the information processing apparatus and the object of the user at or below a predetermined distance are used as a basis for producing the instruction content data; and an information processing executing unit configured to obtain the instruction content data produced by the instruction content data producing unit and for carrying out information processing based on the instruction content data, wherein the information processing includes at least one of: displaying an image element on a display at a position dictated by the instruction content data, and moving the image element based on the instruction content data.
