AN APPARATUS AND METHOD USING EQUALIZATION AND XOR COMPARISION OF IMAGES IN THE VIRTUAL TOUCH SCREEN SYSTEM

A virtual touch screen system performing the effect of a touch screen image is touched without the touch screen device and an operation method are provided to perform feedback control based on color by receiving the image of the user as color by using visible ray. An image storage/output unit outputs outputted image. The output image acquisition unit obtains the outputted image. The storage image/acquired image equalization unit equalizes the storage image and acquired image. The equalization storage image/equalization acquired image XOR comparison unit performs the XOR comparison between the acquired image and the equalized storage image. The user action analysis unit analyzes the operation of the user the XOR comparison result to the natural disposition. The feedback process unit performs the feedback process the action analyzed result to the natural disposition in the output image.
