5. Eye pausing pause when look away Some scenes
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.

6. Eye self-shot Automatic photo when staring at the screen Some scenes
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. 重视

7. Eye zooming Size vary with eyes' distance to screen. Some scenes
Size vary with eyes' distance to screen.
Some scenes
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
1） Analyze students' attention for Online Education.
2） Get millions video audiences’interest and focus.
*Available in next version 重视

9. *Eye unlocking Use iris recognition to unlock the screen . 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.
*Need infrared camera 重视

10. Accurate Eye Center Location
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.
Use fast and robust detectors to find the center of pupil.
Support complicated illumination conditions
Support different pose.

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

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

13. completely Software-based
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.

14. 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 ); }
public void onSightEnter(long time, int flag) {
//4 play video when look at the screen
playVideo( );
} );

15. 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%.

16. Low Power Consumption Key Feature 5 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.

17. www.sightsoft.cn expert at fast and robust image processing
