Siegrun Appelt was born in Bludenz in 1965. She lives and works in Vienna. In her work she focuses on the changing relationship between human perception and technological advances. She studies the phenomena of perception: how does the cognitive processing of sense impressions work? At what point do we as humans reach our limits? What is the correlation between the perception of acoustic and visual stimuli? The »Langsames Licht / Slow Light« concept has dominated her work since 2008 and has a very spe cific aim – to make society rethink its relationship with light. This involves studying the potential offered by the sustainable use of new technology and the development of other aesthetic forms.
