Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for eye gesture recognition. In one aspect, a method includes obtaining an electrical signal that represents a measurement, by a photodetector, of an optical signal reflected from an eye and determining a depth map of the eye based on phase differences between the electrical signal generated by the photodetector and a reference signal. Further, the method includes determining gaze information that represents a gaze of the eye based on the depth map and providing output data representing the gaze information.
Claims15
A system, comprising:
- a machine including a display, the display including a plurality of tunable optical elements;
- a device including circuitry configured to:
- obtain an electrical signal that represents a measurement, by a photodetector, of an optical signal reflected from an eye,
- determine a depth map of the eye based on phase differences between a reference signal and the electrical signal generated by the photodetector, and
- determine a gaze information that represents a gaze of the eye based on the depth map;
- and
- one or more processors in communication with the machine and the device, the one or more processors including one or more storage devices storing instructions that are operable, when executed by the one or more processors, to cause the one or more processors to perform the operations including:
- receiving, from the device, output data representing the gaze information;
- and
- determining the gaze information representing the gaze of the eye in relation to the display of the machine.
A device, comprising:
- a plurality of tunable optical elements for adjusting focal lengths;
- one or more processors in communication with the plurality of tunable optical elements, the one or more processors including one or more storage devices storing instructions that are operable, when executed by the one or more processors, to cause the one or more processors to perform operations comprising:
- obtaining an electrical signal that represents a measurement, by a photodetector, of an optical signal reflected from an eye,
- determining a depth map of the eye based on phase differences between a reference signal and the electrical signal generated by the photodetector,
- determining gaze information that represents a gaze of the eye based on the depth map, the gaze information representing the gaze of the eye in relation to a display of a remote device, and
- activating a tuning of a subset of the plurality of tunable optical elements based on the gaze information.
