Setup

Projector and Webcam/Phone

The size of the playable area is defined by type and positioning of the projector. In this case short-throw ACER 5000 Lumen small room projector was used resulting in 3.5m x 2.5m playing area. A webcam or mobile phone can be mounted next to the projector.


Gameplay: avoid collision with the virtual stick

Webcam or phone camera is tracking a red-labeled real-world puck (tracked puck is seen above the stick and tracker marker is green in the Figure) enabling AI "to see" the puck and drive virtual stick to intercept it. Please check the current app release to check different Gameplay exercises.



Red, green or blue pucks and balls or colored tape-labeled pucks can be tracked by the system.

Exercises on touch screen

Tracked pucks

Red, green or blue pucks and balls or coloured tape-labelled pucks can be tracked by the system.


All exercises can be attempted not only with a tracked real-world puck but also on phone or computer screen with the finger-touch. The use of Stylus on phones gives the best feeling. In the screen capture, finger touch control is indicated by a small green stick blade.
