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 2):
The method as claimed in  claim 1 , before calculating, based on the turning angle and the spatial position relationship between the remote controller and the projection screen, the displacement of the light spot formed on the projection screen by projecting the visible light emitted by the visible light emitter of the remote controller, further comprising:\n under a circumstance that the light spot formed on the projection screen by projecting the visible light emitted by the visible light emitter is overlapped with at least three calibration points projected on the projection screen respectively, acquiring a distance between each calibration point in the at least three calibration points and the remote controller and acquiring an angle between each calibration point in the at least three calibration points and the visible light emitted by the visible light emitter, wherein the at least three calibration points are not on a same straight line; and determining the spatial position relationship between the remote controller and the projection screen based on the acquired distance and angle.
