2. Eye pausing pause when look away Some scenes 1 ） Looked up to see if the station on the subway, the phone automatically pauses the movie. 2 ） Automatically pause games when leave for a while.

3. Eye zooming Size vary with eyes' distance to screen. 1 ） Video gets smaller when close to the screen, for privacy. 2 ） Text gets bigger when close to the screen, suitable for elderly. 重视 Some scenes

4. Eye self-shot 重视 Automatic photo when staring at the screen Some scenes No need to touch any button to take photos, only staring 1-2 seconds. So release your hands. Most natural way to start camera.

5. Focus statistics 重视 Get users’ real-time focus and attention data Some scenes 1 ） Analyze students' attention for Online Education. 2 ） Get millions video audiences 'interest and focus.

6. Passer detect Warn when a passer peek at your phone 1 ） Prevent pervert peeping for the girl on the subway. 2 ） Warning when the boss suddenly appeared from behind. 重视 *Need wide angle camera Some scenes

7. *Eye unlocking Use iris recognition to unlock the screen. 重视 *Need infrared camera Some scenes 1 ） Pick up a locker phone, automatically unlock after user looked at it. 2 ） Automatically lock the phone when detect a stranger’s eye.

8. Key Feature 1 Accurate Eye Center Location Use reliable method to locate the iris border, which is the most notable feature in visible- spectrum eye images. Support complicated illumination conditions Support different pose.

9. Dark face Look up illumination compensation Detect result white rectangle contains detected face white cross is the eye position Key Feature 1 Example: Dark face + Look up left eyeright eye

10. Key Feature 2 Fast Detect one frame < 0.1 second in most phone. Use many highly optimized detectors, which are 10 times faster than standard algorithm. Eye blink 0.3 second

11. Key Feature 3 completely Software-based Easy integration in Android and other systems. Only need hardware is 0.3 Megapixel camera, which is satisfied by most devises. Complete documentation. Many demos with source code. Only need 10 lines of code to implement some amazing eye control function.

12. Key Feature 3 Only 4 lines to implement eye-pausing function. //1 Create HiTrack instance hitrack = HiTrackerPreview.newInstance( null,0x0 ); //2 set Listener hitrack.setSightListener( new HiTracker.SightListener() { @Override public void onSightLeave(long time, int flag) { //3 pause video when look away pauseVideo( time,0x0 ); } @Override public void onSightEnter(long time, int flag) { //4 play video when look at the screen playVideo( ); } } );

13. Key Feature 4 Robust to Light Complex illumination environment HiTrack use a novel O(n) illumination compensation algorithm. In very strong sidelight, increase the accuracy from 30% to 70%.

14. Key Feature 5 Low Power Consumption Dynamic FPS tracking frames vary from 2-20 per second. Only need 1/10 power consumption in low fps mode. For example: 2 fps is right for eye-pausing.

15. www.sightsoft.cn expert at fast and robust image processing Face detection Eye Tracking Image Search Many years’ hard working and coding at fast and robust image processing in the real uncontrolled environments. Novel patents on real-time eye tracking at mobile device.

16. Eye tracking for the future MAIL: cys@sightsoft.cn WeChat: grusoft QQ: 304718494 www.SightSoft.cn
