SightPlane http://sightsoft.cn/fe.apk 1 Move faster Move plane with your eyes. 2 Eye pausing Automatically pause the game when look away 重视

Augmented Reality http://sightsoft.cn/ar.apk 1 Watching picture, pop up a 3-dimensional space scene 2 Roaming in space with eyes 重视

Eye pausing pause when look away Some scenes http://sightsoft.cn/se.apk 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.

Eye self-shot Automatic photo when staring at the screen Some scenes http://sightsoft.cn/se.apk 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

Eye zooming Size vary with eyes' distance to screen. Some scenes http://sightsoft.cn/se.apk 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

*Focus statistics 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. *Available in next version 重视

*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

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.

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

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.

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.

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( ); } );

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%.

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.
