1. A head-mounted display system, comprising:
a first head-mounted display system component;
a plurality of optical detectors carried by the first head-mounted display system component;
a second head-mounted display system component that includes a plurality of light sources; and
control circuitry operative to:
cause one or more of the plurality of light sources to emit light;
receive sensor data from one or more of the plurality of optical detectors;
track a position of the second head-mounted display system component based at least in part on the received sensor data;
process the received sensor data, including to determine whether to disable any one of the plurality of optical detectors or any one of the plurality of light sources based on determined disabling criteria; and
disable each of the optical detectors or the light sources that satisfy the disabling criteria for a respective disabled time period during the tracking of the position of the second head-mounted display system component.
