barriere 1996 -

non-verbal dialog

The space between two persons is cut with a barriere out of light and steel. On the steel plate a group of solar robots waits for energy. The brainwaves of the users are measured by an electrode headband and get analyzed and compared. The result is projected onto the barriere through varying light intensities.

The more the wave spectra of the users equal each other at a certain range, the more a corresponding light is dimmed up. In case of an identical state of both users, all robots move continously.
