Moving shapes: A multiplayer game based on color detection running on public displays

Abstract

Over the past few years the use of public displays has increased drastically, with the most common public displays being flat surface LED walls or projections on walls. Presently interactive public displays often make use of depth cameras. This paper introduces a cheaper variant that allows people to interact with the display and each other by using the color detection abilities of an ordinary webcam. As proof of concept a simple game was created that demonstrates how people are able to control and interact with photographed shapes via their own smartphones. Alternately a special hardware interface was built for users who do not own a smartphone. Contrary to ordinary games, this game works without points; instead, the leading user is awarded the ability to make decisions about game speed and is able to influence the audio through his movements. © 2013 Authors.
