Hello and welcome back to my video. I'm gonna show you how you can control your laptop or PC or can be others kinds of computer(smart phone) using a pen.
I am using what we called OpenCV or we can call ComputerVision.

Computer vision is an interdisciplinary scientific field that deals with how computers can gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to understand and automate tasks that the human visual system can do.
