Abstract:
A projection cursor control method and device and a remote controller are provided. A turning angle of a remote controller is acquired; a displacement of a light spot formed on a projection screen by projecting visible light emitted by a visible light emitter of the remote controller is calculated based on the turning angle and a spatial position relationship between the remote controller and the projection screen; a cursor position represented by a current projection position of the light spot on the projection screen is determined based on the displacement, a pixel width, represented by a horizontal displacement of a unit length on the projection screen, in a horizontal direction and a pixel height, represented by a vertical displacement of the unit length on the projection screen, in a vertical direction; and a cursor in a picture projected on the projection screen is moved to the cursor position.

Claim (Index 12):
The device as claimed in  claim 8 , wherein the second acquisition module is configured to:\n detect an angle change of the remote controller through a sensor on the remote controller, wherein the sensor comprises: a gravity sensor and/or a gyroscope sensor; and calculate the angle between each calibration point in the at least three calibration points and the visible light emitted by the visible light emitter based on an initial angle of the visible light emitted by the visible light emitter and the angle change.
