Abstract
Reflection interference control can comprise: determining, according to identification information comprised in a light signal from a reflection surface to a field of view of a user, that a reflection interference phenomenon exists on the reflection surface; and generating a control signal for lowering the level of the reflection interference. For example, by using the characteristic that a light source identifier is modulated in a light signal transmitted by a light source in the existing wireless optical communication, whether a reflection interference phenomenon exists can be determined according to identification information comprised in a light signal received by a field of view of a user from a reflection surface, and reflection interference is automatically controlled if it is determined that the reflection interference phenomenon exists, which is simple and quick and does not require user intervention.
