hapoco (handy pointing-stick controller) is a Python application that allows you to control your mouse from your webcam using both hands, in a way that mimics a pointing stick. One hand controls the mouse cursor and the other hand performs basic actions, such as left click, right click, drag and drop and scrolling. It is designed to replace a traditional mouse by minimizing any hand or finger movement for accessibility purposes.
From the code repository:
git clone https://github.com/jorisparet/hapoco
cd hapoco
pip install -r requirements.txt
pip install .
After installing the package, call hapoco from a terminal to start controlling the mouse with your hands. Several options and parameters can be set to adjust the experience to your liking (type hapoco --help for more details).
