81 Points of View is an interactive sculpture created by Sebastian Schmieg. It proposes an electro-mechanical setup that overlaps perceived with virtual reality. The result is an elaborate manifestation of a basic principle utilizing old and obsolete technology. Due to the transparent setup the sculpture's mode of operation turns out to be its actual subject matter.
81 Points of View operates in between modern handheld devices that implement augmented reality, and optical machines invented centuries ago. As an installation it attempts to illustrate ideas of optical illusion and virtual voyage that have appeared as new technology repeatedly during past centuries – and continue to do so. See more;
The slide projector's tray can hold 81 slides to which a computer-rendered panorama view is allocated. It can be rotated around its center in 81 steps. After each movement a mechanism selects the slide matching the person's point of view. In order to make the projection appear overlapping the reality a technique called pepper's ghost is used – invented over 150 years ago.
