Drawing based game design

Draw, play, erase, correct, scan & play anew!

In this talk, we will share our experience in designing games that revolve around interactive drawings (felt pen on paper, graff on walls, colored syrup on waffles...). How does such games work? First a camera captures the drawing, then we analyze it, use that information in our game, then we project back the rendered game on the drawing to close the loop.

First we will discuss the implications of such an analogical and free-form input in term of user experience and possible gameplays. Then we will present the tech we have been developing to ease the development process. This implied working both on software (a library, the PTX system) and hardware (a kit for easy setup).
