Virtual Touch Sensing is patent method that applied advanced 3D computer vision and motion detection technologies for resolving the bottleneck of touch control in small panel device such as smart watch, small sized smart phone and other hand held devices. It uses two or more sensors to detect the 3D coordinates of fingertip above the physical touch screen of a hand held device. Then it projects cursor on the respective coordination of touch screen. As the area of the operation surface of the virtual touching area can be much larger than the area of the actual screen, it allows user easily control the cursor navigating on touch screen accurately. The system can detect the touch motion of finger tip (finger tip move toward to the screen), it locks the cursor on the screen. If the cursor is rode on clickable widget, it can trigger the click event of the widget no matter where the screen is touched. So, through this mechanism user can easily control the device in a small hand held or wearable devices.
