This project shows the development of a system based on optical multi-touchcomputer vision, is programming a computer to understand a scene or the characteristics of an image, the system consists of modules, tools andcomputational tools for image processing (detection object tracking, gesture recognition and event generation), which are a set of elements known as man-machine interfaces. By sensor Kinect, in a scene of 3D objects is captured 11-bit image depth, and then apply thresholding and binarization two filters are image processing techniques to obtain a 2D image in order to detect and stay in touch real time poin by the palm of the user’s hands in the region of system operation. Finally getting the result is the development “Optical System Type Multi-touch”
