System and method for tracking eyeball motion
First Claim
1. A system for determining position and/or motion information related to an eyeball of an individual, the eyeball residing within an eye socket of the individual, the system comprising:
- a laser radar system that determines a range and a Doppler velocity for each of one or more points on a surface of the eyeball for substantially the same point in time; and
a monitor module that determines information related to the position and/or the motion of the eyeball based at least in part on the ranges and the Doppler velocities determined by the laser radar system.

Abstract
Detecting position information related to a face, and more particularly to an eyeball in a face, using a detection and ranging system, such as a Radio Detection And Ranging (“RADAR”) system, or a Light Detection And Ranging (“LIDAR”) system. The position information may include a location of the eyeball, translational motion information related to the eyeball (e.g., displacement, velocity, acceleration, jerk, etc.), rotational motion information related to the eyeball (e.g., rotational displacement, rotational velocity, rotational acceleration, etc.) as the eyeball rotates within its socket.

18. A system for determining position and/or motion information related to an eyeball of an individual, the eyeball residing within an eye socket of the individual, the system comprising:
-
a laser radar system that determines at least a Doppler velocity for each of one or more points on a surface of the eyeball for substantially the same point in time; a video imaging system that captures video footage of the eye socket;
wherein the monitor module determines the information related to the position and/or the motion of the eye socket at least in part based on processing the video footage of the eye socket captured by the video imaging system a monitor module that determines (i) information related to the motion of the eye socket at least in part based on processing the video footage of the eye socket captured by the video imaging system, and (ii) information related to the motion of the eyeball within the eye socket based at least in part on the Doppler velocities determined by the laser radar system and the information related to the motion of the eye socket. - View Dependent Claims (19)
