In this project, I made a sketch application for desktop PC and laptop, allowing mid-air gesture control. With the help of the Leap Motion controller, this system can track users' hand gestures and movements in the space in front of the monitor, so that users can draw and use diﬀerent tools with their hands in the air. I used the Unity platform to implement this application. To test the usability of LeapSketch and compare it with other interaction methods like screen touch, a small user test was conducted afterwards. The results showed that LeapSketch was easy to use and could deliver a pleasant user experience. But in comparison with drawing on touch screens, it was less eﬃcient and less precise.
