1. A system comprising:
a wearable device 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 photodetectors;
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; and
a reference device configured to:
determine a location or a movement of the reference device; and
transmit, from the reference device to the wearable device, reference information representing the location or the movement of the reference device,
wherein the one or more processors of the wearable device are configured to determine the action information based on the reference information received by the wearable device, in addition to the depth map of the user.
