Virtual Gesture Screen System Based on 3D Visual Information and Multi-Layer Perceptron

Active research is underway on virtual touch screens that complement the physical limitations of conventional touch screens. This paper discusses a virtual touch screen that uses a multi-layer perceptron to recognize and control Three-Dimensional (3D) depth information from a Time Of Flight (TOF) camera. This system extracts an object's area from the image input and compares it with the trajectory of the object, which is learned in advance, to recognize gestures. The system enables the maneuvering of content in virtual space by utilizing human actions.
