CONTROL METHOD, RELATED DEVICE, AND SYSTEM

The present application provides a control method, a related device, and a system. The method can be applied in an operating device (2). The operating device (2) comprises a plurality of light-emitting modules (101), the light-emitting modules (101) are used for sending positioning optical information, and the positioning optical information is used by a visual device (1) to position the operating device (2). The method comprises: obtaining first motion information of the operating device (2), and controlling, according to the first motion information, the plurality of light-emitting modules (101) to be in their respective currently corresponding working states, wherein the working states comprise a first state and a second state, the first state is a state used for sending positioning optical information, and the power consumption of each light-emitting module (101) in the second state is less than the power consumption of the light-emitting module (101) in the first state, the light-emitting modules (101) c
