Watcher

Very simple application that you may use for tablets that are sticked into any surface with camera faced to you: it analyses the surrounding and detects motion. If the motion is sufficient itlaunches the screen. You may easily adjust the percentage of screen that has to changeWARNING: App is in heavy alpha and if it works for you - I'm very happy. I wanted to test on some devices that don't have adb compatibility so that's why it's on play store.
