Patent ID: 8891025

Claim:
An information processing device operable by a motion of a hand, the information processing device comprising: a display section including a display area and a frame located around the display area; a detection section provided in the frame for detecting the hand and a motion of the hand; and a control section for, while determining that the detection section is detecting the hand based on an output result of the detection section, displaying information indicating the detection of the hand in the display area of the display section, and also displaying information corresponding to the motion of the hand within a prescribed time duration after the hand starts to be detected in the display area of the display section while controlling a target device in accordance with the motion of the hand; when the control section keeps performing the process corresponding to the motion of the hand being stopped, then the detection section detects a motion of the hand, and then the control section determines that the motion of the hand is stopped at a different position, the control section does not consider the motion of the hand detected by the detection section; wherein the information processing device further comprises a speaker for outputting a sound; the target device is a tuner for receiving a TV broadcast; the control section controls the tuner to select a prescribed TV broadcast, to display a video of the selected broadcast in the display area of the display section, and to output a sound of the selected broadcast from the speaker; the detection section detects that the hand is still at either one of a first position in the frame and a second position in the frame distanced from the first position for a prescribed time duration, or detects that the hand moved from one of the first position and the second position to the other of the first position and the second position within the prescribed time duration; when the detection section detects that the hand is still at the first position in the frame for the prescribed time duration, the control section increases a sound volume of a sound of the selected broadcast and displays information indicating the sound volume at the time in the display area while it is detected by the detection section that the hand is still; and when the detection section detects that the hand is still at the second position in the frame for the prescribed time duration, the control section decreases the sound volume of the sound of the selected broadcast and displays information indicating the sound volume at the time in the display area while it is detected by the detection section that the hand is still.
