I applaud projects like this, but it really needs hardware specialized for eye tracking. Unfortunately, every hard word project I've encountered is focused on research and its price reflects that when it's in a thousands of dollars. Way out of reach for those that are disabled. https://www.tobii.com/. tobii is by far the most price accessible around $250. Unfortunately, their licensing is hostile against those who need an accessible product. They won't even allow you to create a Python wrapper to make it easy to integrate with accessibility projects. (Even if you're not storing gaze data). So there needs to be accessible hard worth accessible licensing for those with disabilities.
