Eye gesture tracking

A system comprising:

• a plurality of tunable optical elements;
• one or more photodetectors configured to receive light reflected from a user of the system and to generate one or more electrical signals based on the received light;
• and
• one or more processors electrically coupled to the plurality of tunable optical elements and the one or more photodetectors, the one or more processors configured to:
• obtain time-of-flight information corresponding to phase differences between a reference signal and the one or more electrical signals generated by the one or more photo detector s;
• determine a depth map of the user that comprises a depth map of an eye of the user based on the time-of-flight information;
• determine, based on the depth map of the user, action information that corresponds to an action of the user;
• and
• provide one or more outputs for adjusting one or more of the plurality of tunable optical elements based on the action information.

A tracking method, comprising:

• generating, by one or more photodetectors, one or more electrical signals in response to light reflected from a user and received by the one or more photodetectors;
• obtaining, by a computing system having one or more processors electrically coupled to a plurality of tunable optical elements and the one or more photodetectors, time-of-flight information corresponding to phase differences between a reference signal and the one or more electrical signals generated by the one or more photodetectors;
• determining, by the computing system, a depth map of the user based on the time-of-flight information, the depth map of the user comprising a depth map of an eye of the user;
• determining, by the computing system and based on the depth map, action information that corresponds to an action of the user;
• and
• providing, by the computing system, one or more outputs for adjusting one or more of the plurality of tunable optical elements based on the action information.

A system comprising:

• a display;
• one or more photodetectors configured to receive light reflected from a user of the system and to generate one or more electrical signals based on the received light;
• and
• one or more processors electrically coupled to the display and the one or more photodetectors, the one or more processors configured to:
• obtain time-of-flight information corresponding to phase differences between a reference signal and the one or more electrical signals generated by the one or more photo detector s;
• determine a depth map of the user comprising a depth map of an eye of the user based on the time-of-flight information;
• determine, based on the depth map of the user, action information that corresponds to an action of the user;
• and
• provide one or more outputs for adjusting the display based on the action information.
