Panel Perception and Illusion: Ulf Langheinrich: Interference Moments (Sonic Acts XII, 2008)
Sonic Acts is a biannual festival at the intersection of arts, science, music & technology. Cinema creates an illusion through the projection of 2D-images and sound. But what if we go beyond the audiovisual illusion? And what are the tricks that cinema can use to affect how the brain processes information in the visual cortex? A researcher and a media artist share their views. Frank Kooi (NL) received his PhD from the School of Optometry at University of California, Berkeley, in 1990. He is currently leader of the Applied Perception group at TNO Human Factors where he combines knowledge of human perception with technological developments. The German media artist Ulf Langheinrich (D) founded the media art collaboration Granular Synthesis together with Kurt Hentschläger. They created numerous large scale immersive installations such as Modell5, Noisegate and Areal. Since 2003 Langheinrich has realised various solo projects aimed at achieving a direct sensory impact. These works focus on creating specific modulations of the projected material in time and the projection-space, and on effecting interference movements between the perceptive and processing potential of the eye-brain apparatus. This talk was given as part of the panel 'Perception and Illusion', together with Frank Kooi, on 23 February, 2008.
