Hand -drawing is an screen-based installation that uses a camera capturing a user's hand motion and creating an aesthetic painting along the way. The viewer will create a drawing pattern by using nature waving gestures.Several stokes with their own behavior will follow the position of the moving objects in front of camera. The experience differs as the painting goes. At first, the viewer will experience the joy of using natural movement to control the drawing and then as the number of stroke increases, the drawing beneath the stroke begins to reveal. The viewer then would then experience the unique ,none-repeatable recreating process of a particular artwork.
