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 10):
A remote controller comprising: a distance detector, a sensor, a visible light emitter, a signal transceiver and a processor, the distance detector, the sensor, the visible light emitter and the signal transceiver being connected with the processor respectively, wherein\n the sensor is configured to acquire a turning angle of the remote controller; the sensor and the distance detector are further configured to acquire a spatial position relationship between the remote controller and a projection screen; the visible light emitter is configured to emit a visible light to project a light spot on the projection screen; the processor is configured to calculate, based on the turning angle and the spatial position relationship between the remote controller and the projection screen, a 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; the processor is further configured to determine 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 the signal transceiver is configured to send the cursor position to a projection source to enable the projection source to move a cursor in a picture projected on the projection screen to the cursor position.
