This video talks about the possibilities of the Totemagi playground concept (in Danish). Here's a summary in English: Children like to play computer games, but they don't play outside, where they can get physical exercise. The Totemagi playground facilitates computer games. It can also be connected to an internet game portal, so that the children can put game parameters into the playground from their home computer. Other than blinking, LEDs embedded in the rubber surface can display game symbols. By wearing RFID tags on their shoes, the children can be recognized by the playground.
