"Color Vision", a study project by Alexander Wiethoff from Linz, focuses on physical interaction and communication. Visitors can change the room colors by the way in which they hold their bodies. Their physical postures symbolize their mental attitudes and are visualized by the color in the room.
For example, a person sitting in an open posture with outstretched arms will produce the color red, which expresses liveliness. The color green stands for creativity and appears whenever someone adopts a reflective posture by resting their head on their hands. A reserved posture with folded arms will plunge the room in a cool blue color.
