Abstract: Systems and methods for tracking the position of one or more head-mounted display (HMD) system components of an HMD system. The HMD components may carry a plurality of angle sensitive detectors or other types of detectors. The HMD system may be operative to detect corrupted position tracking samples, allowing such samples to be ignored, thereby improving the position tracking process. Control circuitry causes light sources to emit light according a specified pattern, and receives sensor data from the plurality of detectors. Control circuitry may process the sensor data, for example using machine learning or other techniques, to track a position of one or more HMD components.

Abstract: A visual interface for a PTT user terminal displays user images of participants in a PTT conference. When a PTT conference is established, a controller determines whether an image associated with each participant invited to the PTT conference is stored in memory on the user terminal. For each participant that has an associated image stored on the user terminal, the controller displays the image. For those participants that do not have an associated image stored on the user terminal, the controller generates and sends a request for the image. Upon receipt of the image, the controller displays the image on the user terminal. During the PTT conference, the controller alters the appearance of the images to show the status information of each participant, such as which participant has floor control and presence of participants.
