Abstract: Systems and methods for adaptive frequency hopping for reducing or avoiding electromagnetic interference between two radios operating in the same radio frequency (RF) band are provided. In one aspect, a host device, which includes first and second wireless radios and a hardware processor, can use adaptive frequency hopping among a plurality of RF channels to reduce interference. The device can control the first wireless radio to establish a first wireless connection with a terminal device via a first subset of channels, determine a set of performance statistics for the channels, and replace at least one of the first subset of the channels with a new channel within the plurality of channels based on the statistics. For example, a channel can be replaced if a packet error rate (PER) exceeds a threshold.

Abstract: Wearable systems and method for operation thereof incorporating headset and controller localization using headset cameras and controller fiducials are disclosed. A wearable system may include a headset and a controller. The wearable system may alternate between performing headset tracking and performing controller tracking by repeatedly capturing images using a headset camera of the headset during headset tracking frames and controller tracking frames. The wearable system may cause the headset camera to capture a first exposure image an exposure above a threshold and cause the headset camera to capture a second exposure image having an exposure below the threshold. The wearable system may determine a fiducial interval during which fiducials of the controller are to flash at a fiducial frequency and a fiducial period. The wearable system may cause the fiducials to flash during the fiducial interval in accordance with the fiducial frequency and the fiducial period.
