Muurprojectie voor kinderen met ballen! | Raoul

Interactive Game-Wall Projection

Calibration

To tell the camera where and how large the projection is, you must first calibrate it. Therefore you use the Camera-Crop-page.

Connect the beamer to your laptop
Connect your webcam, or point your laptop-webcam to the wall
Point the beamer to the same wall and switch it on
Open Camera-Crop-page
Accept access to use your webcam
On the Camera-Crop-page, use your mouse to drag a rectangular shape exactly over the beamer-surface.
Then click on "Back". That's it! And do not move your setup now, else you need to re-callibrate

NOTE 1: Usb-cams absorb light very differently.
Best light-situation: dusky room.

NOTE 2: Projection needs a webcam and a browser with webcam enabled. So this web-projection is not useful on mobile devices.
