A method for updating a gaze direction for a transmitter avatar in a receiver headset is provided. The method includes verifying, in a receiver device, that a visual tracking of a transmitter avatar is active in a transmitter device, and adjusting, in the receiver device, a gaze direction of the transmitter avatar to a fixation point. Adjusting the gaze direction of the transmitter avatar comprises estimating a coordinate of the fixation point in a receiver frame at a later time, and rotating, in the receiver device, two eyeballs of the transmitter avatar to a point in a direction of the fixation point. A headset, a memory in the headset storing instructions, and a processor configured to execute the instructions to perform the above method, are also provided.

Gaze adjusted avatars for immersive reality applications

A method for training a real-time, modeling for animating an avatar for a subject is provided. The method includes collecting multiple images of a subject. The method also includes selecting a plurality of vertex positions in a guide mesh, indicative of a volumetric primitive enveloping the subject, determining a geometric attribute for the volumetric primitive including a position, a rotation, and a scale factor of the volumetric primitive, determining a payload attribute for each of the volumetric primitive, the payload attribute including a color value and an opacity value for each voxel in a voxel grid defining the volumetric primitive, determining a loss factor for each point in the volumetric primitive based on the geometric attribute, the payload attribute and a ground truth value, and updating a three-dimensional model for the subject. A system and a non-transitory, computer-readable medium storing instructions to perform the above method are also provided.
