Eye pausingpause when look away
Some scenes1 ） 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.
Eye zoomingSize 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
Eye self-shot
重视
Automatic photo when staring at the screen
Some scenesNo need to touch any button to take photos, only staring 1-2 seconds. So release your hands. Most natural way to start camera.
Focus statistics
重视
Get users’ real-time focus and attention data
Some scenes1 ） Analyze students' attention for Online Education.2 ） Get millions video audiences 'interest and focus.
Passer detectWarn 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
*Eye unlocking Use iris recognition to unlock the screen .
重视
*Need infrared camera
Some scenes1 ） Pick up a locker phone, automatically unlock after user looked at it.2 ） Automatically lock the phone when detect a stranger’s eye.
Key Feature 1
Accurate Eye Center LocationUse 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.
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 eye right eye
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
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.
Key Feature 3Only 4 lines to implement eye-pausing function.
//1 Create HiTrack instancehitrack = HiTrackerPreview.newInstance( null,0x0 );//2 set Listenerhitrack.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( ); }} );
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%.
Key Feature 5
Low Power Consumption
Dynamic FPStracking 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.
