Abstract: Various aspects of the subject technology relate to prediction of eye movements of a user of a head-mountable display device. Predictive foveated display systems and methods, using the predicted eye movements are also disclosed.

Abstract: A shared communication channel allows for the transmitting and receiving audio content between multiple users. Each user is associated with a headset configured to transmit and receive audio data to and from headsets of other users. After the headset of a first user receives audio data corresponding to a second user, the headset spatializes the audio data based upon the relative positions of the first and second users such that when the audio data is presented to the first user, the sounds of the audio data appear to originate at a location corresponding to the second user. The headset reinforces the audio data based upon a deviation between the location of the second user and a gaze direction of the first user, allowing for the first user to more clearly hear audio data from other users that they are paying attention to.
