GOTCHA

In GOTCHA (Generative Observational Turing Test To Tell Computers And Humans Apart), the fading of the perceptual boundary between humans and machines is explored. In the work, human and machine and their respective representations meet.
As soon as the visitor enters the work, his position is tracked by the computer. After a short time, a white shadow generated by the computer appears - the virtual representation of the visitor. This shadow also reveals the person's cast shadow, which is made visible by the light of the projector. The calculated white shadow never completely overlaps with the real shadow, but follows the visitor's position. After a few seconds, the screen is overlaid with a pattern similar to CAPTCHAs. Finally, a black shadow appears, which is also calculated and projected by the computer. Here, the shadow's position in space is determined seemingly independently of the visitor, its movement being based on the movements of previous visitors.
