Wall Game

Little Quran Kids

Project onto the wall, point a camera at the same wall, and children play by putting their hands on the glowing shapes. Their shadow is the button.

1 Full screen first

Press this before you mark the corners. The gold brackets must be in the same place during setup and during the game — if the picture changes size afterwards, every shape moves and nothing triggers.

2 Turn on the camera

Sit the camera next to the projector, facing the wall. It must see the whole projected picture, plus a little margin. If your laptop has its own webcam, pick the right camera in the list — the built-in one is usually pointing at you, not at the wall.

3 Mark the corners

Drag dots 1 2 3 4 in the camera picture onto the matching gold corner brackets you can see on the wall. Get this right and everything else works. Click a dot and use the arrow keys for fine nudges.

4 Set the sensitivity

Higher number = harder to trigger. Start at 18. If shapes pop by themselves, raise it. If hands don't register, lower it.

The bar shows how much light is changing right now in the middle of the wall. The white line is your number. Wave a hand at the middle of the wall — the bar should jump well past the white line.

During play: Esc goes back here · Space pauses · F toggles full screen · you can also click shapes with the mouse to test without anyone at the wall.
