  • Patent number: 11425644
    Abstract: Apparatuses, methods, and systems are disclosed herein to provide an information processing apparatus and a control method which do not cause a reduction in the output of radio waves when a human body is not approaching. A communication unit communicates with other devices wirelessly, a detection unit detects a physical quantity varying with the approach of an object, and a control unit causes the communication unit to reduce the output of radio waves when the amount of change in physical quantity exceeds a predetermined threshold value. When a predetermined member is in a position to approach a first chassis on which the communication unit and the detection unit are mounted, the control unit compensates for a change in physical quantity detected by the detection unit due to the approach of the member.
