Abstract
Systems and methods are described for estimating a direction of interest of a user. In some embodiments, a method of estimating a direction of interest of a user includes tracking a head orientation of the user, detecting a shift in the head orientation, determining a head rotation rate during the shift in the head orientation, and estimating the direction of interest of the user based at least in part on the head rotation rate.
Claims20
A method comprising:
- tracking a head orientation of a user;
- detecting a shift in the head orientation of the user;
- determining a head rotation speed of the user during the shift in the head orientation;
- determining a user-specific parameter relating the head rotation speed to at least one of a gaze direction or a direction of interest;
- and
- estimating the at least one of the gaze direction or the direction of interest based at least in part on the user-specific parameter and the head rotation speed.

A method, performed at least in part by a head-mounted display (HMD) configured to be worn by a user, comprising:
- tracking a head orientation of the user;
- detecting a shift in the head orientation;
- determining a head rotation speed during the shift in the head orientation;
- determining a user-specific parameter relating head rotation speed to at least one of a gaze direction or a direction of interest;
- estimating the at least one of the gaze direction or the direction of interest based at least in part on the user-specific parameter and the head rotation speed;
- and
- rendering an image for the user at the HMD using foveated rendering based on the at least one of the gaze direction or the direction of interest.
4 more elements
An apparatus comprising:
- a processor;
- and
- a memory storing instructions operative, when executed by the processor, to cause the apparatus to:
- track a head orientation of a user;
- detect a shift in the head orientation of the user;
- determine a head rotation speed of the user during the shift in the head orientation;
- determine a user-specific parameter relating the head rotation speed to at least one of a gaze direction or a direction of interest;
- and
- estimate the at least one of the gaze direction or the direction of interest based at least in part on the user-specific parameter and the head rotation speed.
