1. A control method comprising:
detecting a first object within a first range corresponding to an output device, the first object including a bystander of the output device;
obtaining a first relative position relationship between the first object and the output device; and
adjusting an output parameter of output light of the output device based on the first relative position relationship, to cause the output device to be in a first output state relative to the first object, to cause brightness of the output light of the output device in an output area to be uniform in response to the output area being viewed at a position within the first range, to cause the first object to see a black screen with the uniform brightness, and to cause a second object to receive the output light of the output device to identify output content of the output device, the second object being different from the first object.
