Eye tracking
An apparatus ( 100 ), comprising a transparent capacitive sensor ( 102 ); a body ( 101 ) configured to support the transparent capacitive sensor in front of an eye ( 112 ) of a user ( 110 ); and a driver ( 106 ) configured to receive signals from the sensor and to determine eye movements based on the received signals, wherein the sensor ( 102 ) is configured to detect movement of the eye ( 112 ) based on electrostatic effect caused by a bulge of the cornea of the eye ( 112 ). The apparatus may be wearable by the user like eyeglasses.
1. An apparatus, comprising:
a transparent capacitive sensor;
a body configured to support the transparent capacitive sensor in front of an eye of a user; and
a driver configured to receive signals from the sensor and to determine eye movements based on the received signals.
2. The apparatus of claim 1 , wherein the sensor is configured to detect movement of the eye based on electrostatic effect caused by a bulge of eye cornea.
3. The apparatus of claim 1 , wherein the apparatus is wearable by the user.
4. The apparatus of claim 1 , wherein the apparatus is wearable as eyeglasses.
5. The apparatus of claim 1 , wherein the apparatus comprises a display configured to enable the apparatus to be worn as video glasses.
6. The apparatus of claim 5 , wherein the sensor is attached to the display.
7. The apparatus of claim 1 , wherein the sensor comprises two layers of transparent conductive material sandwiching a layer of non-conductive material.
8. The apparatus of claim 1 , wherein the sensor is integrated with a lens of eyeglasses.
9. The apparatus of claim 1 , further comprising a touch controller.
10. The apparatus of claim 9 , wherein the touch controller is configured to detect touching of the user at one or more touch sensitive areas in the body and/or on the driver.
11. The apparatus of claim 1 , further comprising a heartbeat detector.
12. The apparatus of claim 11 , wherein the heartbeat detector is integrated with or attached to the body.
13. The apparatus of claim 1 , further comprising a wireless connection interface for connecting with an external device.
14. A method comprising:
supporting a transparent capacitive sensor in front of an eye of a user;
sensing movement of the eye of the user by the transparent capacitive sensor and producing corresponding signals; and
determining eye movements based on the produced signals.
15. The method of claim 14 , wherein the sensor is configured to detect movement of the eye based on electrostatic effect caused by a bulge of eye cornea.
16. The method of claim 14 , wherein the apparatus is wearable by the user.
17. The method of claim 14 , further comprising detecting touching of the user at one or more touch sensitive elements.
18. The method of claim 17 , further comprising carrying by a common body the transparent capacitive sensor and the one or more touch sensitive elements.
19. The method of claim 14 , further comprising detecting heartbeat of the user.
20. A method comprising:
receiving signals from a transparent capacitive sensor located in front of an eye of a user; and
determining movement of the eye based on the received signals.
21. A non-transitory memory medium comprising a computer program that comprises:
code for receiving signals from a transparent capacitive sensor located in front of an eye of a user; and
code for determining movement of the eye based on the received signal;
when the computer program is run on a processor.
