Users slide a screen along an almost life size print of car, enabling the user to see an X-ray like view with animated pop-ups containing added information about parts of the car.

The installation had to rely as little on fabrication as possible so I decided to use computer vision rather than electronics/sensors to detect the screen position. An Infrared camera and light are mounted on the back of the sliding screen, along with the computer. A graphic of a black triangle on a white background runs the length of the print, positioned in front of the camera lens. The camera then monitors this triangle’s width to calculate where along the print it is and the application animates accordingly. Developed with C++ using OpenFrameworks.
