ZeroTouch is the new emergence of sensing technologies as a touch-free interaction of air writing. The main objective of this paper is to use the pen with motion mode of interaction for the efficient online gesture. The virtual pen is detected in webcam with different contour detection is made along with eraser functionalities. But it is made much easier with OpenCV technologies. To display the text from speech in clear format a whiteboard function is added using Tkgui toolkit. A faster region-based convolution neural network technique is proposed for image text detection and then the detected image is converted to text and saved in different image formats.
