Abstract

An information processing apparatus can recognize a first operation made up of a first input and a second operation made up of the first input and an input that follows after the first input. Input by an operating object is detected, starts a response corresponding to the first operation after the first input from the operating object is detected, regardless of existence of any input to follow after the first input, in a case that information relating to movement of the operating object moving in a direction parallel to an input subject face, which is the subject for the operating object to perform the first input, satisfies a predetermined condition.
