Abstract: A programmable display device (i) identifies a switch indicated by a pointing element based on one or two first detected values (in one or two of three directions of a three-dimensional space) of detected values indicative of the position of the pointing element in the three-dimensional space detected by a proximity sensor and (ii) detects a pressing action with respect to the switch based on a second detected value which is a value in another one of the three directions (pressing action detecting direction) other than the direction in which the switch was identified. The programmable display device calculates the amount of movement of the pointing element in the pressing action detecting direction based on a change in the second detected value, and determines whether or not the pressing action of the pointing element with respect to the switch is effective based on the amount of movement.
