Perspection is an audiovisual installation exploring the perception of space through the use of projection on a series of specifically oriented projection surfaces and specialized audio”. It is created by Matthew Biederman and Pierce Warnecke and took place at various places in 2015 and 2016. Although the Perspection uses trompe-l’oeil (=deceive the eye), the technique that tricks the viewer into perceiving two-dimensional objects as three-dimensional or real, its creators went the illusion to the next level. “Perspection seeks to embed the physical experience of perception in place and create a hyperawareness of the act of perception versus a disembodiment or virtual space by correlating screen space with physical space”.

The installation uses three vertical screens, one behind and next to the other, which show oscillating stripes or Necker Cubes at the same time, giving the viewer the impression that it is just one screen, if they stand at the right view angle. To achieve this illusion, the creators used the TouchDesigner visual programming language. The anamorphic images shown at the screens are accompanied by audio.

What makes the experience unique is the use of Kinect –a line of motion sensing input devices-, which tracks down the position of the viewer and adjusts the perspective of both the images and audio. That way, viewers can interact with the installation itself. While the installation was created and staged using three screens, the creators announced that the number of projection surfaces and the loudspeakers may differ and be more to other installations, depending on the space and equipment available at the location it is going to take place.
