Summary:The invention discloses an infrared optical touch interaction method which is established on a hardware structure of an optical machine used for projecting pictures, an acquisition module used for acquiring picture images of an identification area, a touch pen used for emitting light spots with specific wavelengths and a CPU module used for processing acquired information. According to the method, the light spots can be identified more effectively and interference points can be eliminated by acquiring the contact points and optimizing an identification algorithm, the light spots outside a projection picture area can be shielded by the algorithm based on fitting of positioned coordinates, and the anti-interference performance of touch control can be well improved through the optimization. Meanwhile, the method provided by the invention has a simple operation identification process, is faster in identification, and is beneficial to improving the customer experience. Automatic correction of touch control can be
