Abstract

An information processing apparatus includes a distance obtaining unit which obtains information indicating a degree of proximity between an operation object and a predetermined surface, a reference determination unit which determines a first reference value associated with the degree of proximity based on transition of the degree of proximity during one touch input to the predetermined surface by the operation object after a start of the one touch input is recognized, a condition determination unit which determines, during the one touch input, a first condition associated with the degree of proximity for recognizing an end of the touch input based on the determined first reference value, and a recognition unit which recognizes an end of the touch input when the degree of proximity indicated by the information obtained by the distance obtaining unit satisfies the first condition determined by the condition determination unit.
