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 6):
The method as claimed in  claim 3 , wherein determining the pixel width, represented by the horizontal displacement of the unit length on the projection screen, in the horizontal direction and the pixel height, represented by the vertical displacement of the unit length on the projection screen, in the vertical direction based on the spatial position relationship comprises:\n calculating a distance between every two calibration points in the at least three calibration points based on the spatial position relationship; and determining the pixel width, represented by the horizontal displacement of the unit length on the projection screen, in the horizontal direction and the pixel height, represented by the vertical displacement of the unit length on the projection screen, in the vertical direction based on a pixel width and pixel height between every two calibration points in the three calibration points and the distance between every two calibration points in the at least three calibration points.
