MOTION SENSING INTERFACE
First Claim
1. A remote controller for an electronic appliance, comprising:
- a display screen for displaying icons representing possible operations of the electronic appliance;
a motion detector for detecting a hand motion within a field of view of the motion detector, the motion detector first detecting a user'"'"'s hand within the field of view as an indication that a remote control operation is to be started and, thereafter, tracking the movement of the hand and outputting a cursor control signal representative of the motion of the hand;
a control circuit, connected to the display screen, the electronic appliance, and the motion detector and supplied with the cursor control signal, for controlling the display screen to display a movable visual indicator which tracks the movement of the moving hand and for controlling the electronic appliance to perform operations corresponding to the icons selected by the user using the visual indicator.

Abstract
An electronic appliance remote controller which includes a display screen (which may be part of the appliance, e.g. a TV screen) for displaying icons representing possible operations of the electronic appliance, and a motion detector circuit for detecting a motion within a field of view of the motion detector circuit. The motion detector circuit either detects an image of the user'"'"'s hand or a predetermined motion of a moving hand within the field of view as an indication that a remote control operation is to be started and, thereafter, tracks the movement of the hand. The motion detector circuit outputs a cursor control signal representative of the motion of the hand. A control circuit, connected to the display screen, the electronic appliance, and the motion detector circuit and supplied with the cursor control signal, controls the display screen to display a movable visual indicator, e.g. a cursor, whose own motion tracks the movement of the moving hand and the electronic appliance to perform operations corresponding to the icons selected by the user using the visual indicator. In one embodiment, two cameras allow three dimensional movements of the user'"'"'s hand to control the electronic appliance.

25. A method of remote controlling an electronic appliance, comprising the steps of:
-
displaying icons on a display screen representing possible operations of the electronic appliance;
detecting a hand motion within a field of view of the motion detector by the steps of first detecting a user'"'"'s hand within the field of view as an indication that a remote control operation is to be started and, thereafter, tracking the movement of the hand and outputting a cursor control signal representative of the motion of the hand;
controlling the display screen to display a movable visual indicator which tracks the movement of the moving hand and for controlling the electronic appliance to perform operations corresponding to the icons selected by the user using the visual indicator.

49. A remote controller for an electronic appliance, comprising:
-
a display screen for displaying icons representing possible operations of the electronic appliance;
a motion detector for detecting a body part motion within a field of view of the motion detector, the motion detector first detecting a user'"'"'s body part within the field of view as an indication that a remote control operation is to be started and, thereafter, tracking the movement of the body part and outputting a cursor control signal representative of the motion of the body part;
a control circuit, connected to the display screen, the electronic appliance, and the motion detector and supplied with the cursor control signal, for controlling the display screen to display a movable visual indicator which tracks the movement of the moving body part and for controlling the electronic appliance to perform operations corresponding to the icons selected by the user using the visual indicator;
wherein the motion detector includes a video camera, a random access memory (RAM), a RAM interface for storing a video output signal from the video camera in the RAM, and a central processing unit (CPU) connected to the RAM interface for comparing the pixel values of each macro block between two time sequential video frames in a video output signal from the video camera and determining that motion has taken place with respect to a macro block if the difference in pixel values between the two video frames for that macro block exceed a predetermined threshold value and, if so, determining that macro block to be an active region; and
wherein the control circuit includes an on screen display (OSD) circuit controlled by the CPU.
