Abstract: Touch screens have become increasingly popular and widely used in most human-computer interfaces. We present a new low-cost touch display method based on handling projectors using image processing, in which we use object detection instance segmentation and key points detection to improve the efficiency of touch detection and reduce the probability of misrecognition. We are using a high-definition camera and Torch with red beam light that provides more touch accuracy which converts the camera coordinates to space coordinates. The main idea is to make it easy to handle a projector using fingertip processing using the OpenCV library. Here we handle some projector functionality like swipe left and right and virtual typing using Fingertip. We can easily convert a simple projector into an interactive projector using just a webcam through image processing.

Keywords: Image Processing, OpenCV, Camera coordinates -to- Space coordinates, Touch Detection, Infrared Touch Model.
