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 1):
A projection cursor control method comprising:\n acquiring a turning angle of a remote controller; calculating, based on the turning angle and a spatial position relationship between the remote controller and a projection screen, a displacement of a light spot formed on the projection screen by projecting a visible light emitted by a visible light emitter of the remote controller; determining a cursor position represented by a current projection position of the light spot on the projection screen 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, wherein the cursor position comprises a pixel position in the horizontal direction and a pixel position in the vertical direction; and moving a cursor in a picture projected on the projection screen to the cursor position.
