Hey there! , gui, mouse control, opencv, pd inverse kinematics l702x landmark linux logs mouse control multithreading opencv. Re: Re: Move mouse pointer via image processing I'm not sure about what mouth movements you will track, but if you will detect the mouth as a blob, I think you need to determine a mouth point as reference (it could be the mouth center point) and use that point to relate the mouth with the cursor position. But you can simply change this to identify any other object and move the pointer according to that. These two methods are the most popular in the maker and hacker communities and represent the simplest ways to detect and recognize the gesture of humans to control robots.

This tutorial will help you become more familiar with creating your own user interfaces for any applications you are trying to build with platforms like Arduino and Raspberry Pi. It would track the user's eyes (which would move the mouse pointer) using a webcam and would perform click/double click on blink of the eyes. Control mouse. In summary, it captures the x-y coordinates of the mouse pointer between the time you start to draw a digit by pressing 's' (more on this later) and the time you release the left mouse button. To control the servos, I have used pigpio module instead of RPi. NET wrapper for openCV, to perform image processing, through which we try to recognize hand gestures and control mouse using these gestures. wheel(1) Finally, you can record all mouse events and then replay them: # record until you click right events = mouse.
