    Digital networks have been widely used for transmitting messages that contain information in the form of text, image, sound, or video. While our experience with networks is highly informational through digital media, it doesn't reflect the physical qualities of human activity. Through integrating information processing and networking technologies into architectural elements, it is possible to explore new experiences in physical space. Under Control is a networked dynamic ceiling that is responsive to people passing by or standing under it. Under Control transmits negative and positive physical space as a message over a digital network.

Due to the time constraints only a two tile prototype is produced. In this prototype, two dynamic ceiling tiles send their changing forms to each other through the two-wire interface. Each tile moves up and down both by the interaction of people passing under them and by the messages received from the other tile.

  Under Control   Sharp infrared sensors are placed in the center of the cardboard tiles. These sensors are also controlled by the same controller boards. The sketch on the far left shows the control and communication mechanism.

Natalie Jeremijenko's Live Wire project (1994) is one of the early examples of information visualization in physical space.
