Make your screen touch sensitive (sort of) Posted by EvilDavid75 on Friday September 18, 2015 @09:37AM from the sidleeparis.github.io dept. https://sidleeparis.github.io/knock/#sidlee ( 1 comment | 3 points | on HN )
Only works on Chrome and Firefox (uses getUserMedia), should only be used on non touch devices.
It analyses the translation of the image of your webcam to detect if your screen has moved.
Best usage conditions:
- laptop with webcam on top
- laptop on a flat table (not on your laps)
- decent luminosity
- make sure you're not sitting before a monochrome background
