Abstract
A head-mounted display (HMD) is wirelessly coupled to a console or a relay depending on the relative positions of the HMD, the console, and the relay. The HMD communicates wirelessly with the console using a narrow beam that is oriented in a particular direction. As the position of the HMD changes, the quality of the communication link between the HMD and the console may degrades. In response to the degradation, the HMD forms a communication link with a relay, which operates as an intermediary between the HMD and the console. The relay communicates with the HMD over a dedicated communication channel that is isolated from the communication channel over which the relay communicates with the console. A calibration module in the relay iteratively adjusts a noise reduction parameter until the effects of the undesirable feedback are eliminated.
