Making Concrete Interactive
Tokihiko Fukao of the University of Tokyo has developed a new kind of light-sensitive concrete.
Tokihiko Fukao of the University of Tokyo has developed a new kind of light-sensitive concrete. The material is sensitive to ambient light levels, able to take note of the luminosity distribution across its surface. The incoming light level data is then routed to a computer. This turns the concrete into a kind of control surface where varying degrees of illumination can be used to direct different audio and visual outputs.
Transmaterial explains more:
Light-Sensitive Concrete consists of concrete, embedded optical fibers, photodiodes, and electrical circuitry. Optical fibers are distributed within a regular grid, and sensors are attached beneath them in the same arrangement. The interactive properties of the material are intentionally hidden within what appears to be conventional concreteâ€”suggesting possibilities for other light-sensitive building materials and surfaces as part of a total ambient interactive system.
