Abstract
An eye tracking device for integrating in a frame for mounting to a user's head includes a laser output unit for fixing to the frame. The laser output unit is configured to provide a laser beam for illuminating a cornea of the user's eye when in use. The eye tracking device also includes a receiver unit for fixing to the frame. The receiver unit is configured to receive a reflection of the laser beam and to provide a tracking signal usable for determining a distance or velocity of the cornea. The eye tracking device further includes a processing unit for determining a rotation of the user's eye from the tracking signal.
Claims16
An eye tracking device for integrating in a frame for mounting to a user's head, the device comprising;
- a laser output unit for fixing to the frame and configured to provide a laser beam for illuminating a cornea of the user's eye when in use;
- a receiver unit for fixing to the frame and configured to receive reflections of the laser beam and to provide a tracking signal usable for determining a distance or velocity of the cornea;
- and
- a processing unit for determining a rotation of the user's eye from the tracking signal.
A method of eye tracking comprising:
- mounting a frame to a user's head;
- illuminating a cornea of the user's eye with a laser beam provided by a laser output unit fixed to the frame;
- receiving a reflection of the laser beam with a receiver unit fixed to the frame and providing a tracking signal usable for determining a distance or velocity of the cornea;
- and
- determining with a processing unit a rotation of the user's eye from the tracking signal.
