Earlier we reported a Nokia patent about wearable “Nokia Glass”. It is a see-through display which can be used to display external information.
Now, there is one more recent patent which is about “capacitive eye tracking sensor“. This sensor is gain fitted in a wearable glass as can be seen in the below diagram.
According to the claim, the sensor is configured to detect movement of the eye based on electrostatic effect caused by a bulge of eye cornea.
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 or 2, wherein the apparatus is wearable by the user.
4. The apparatus of any of the preceding claims, wherein the apparatus is wearable as eyeglasses.
5. The apparatus of any of the preceding claims, wherein the apparatus is wearable as video glasses.
The patent also talks about its possible uses and there are many,
1 . Activity Recognition 2. Advertising studies 3. Cognitive Studies 4. Communication systems for disabled 5. Computer usability studies 6. Enriched image and video communications where eye movements indicate feelings or reactions 7. Fatigue Detection 8. Geriatric Research 9. In-vehicle Research 10. Medical Research 1 1 . Training Simulators 12. Vehicle Simulators 13. Virtual Reality
