Overview

The Expression Wall was an interactive drawing wall Red Paper Heart built as a permanent installation at Deloitte University. A low-res LED wall sat behind slats of plexiglass, which turned the pixels into a soft, unusual screen. A touch frame over the surface let visitors draw with their hands, and a Kinect camera picked up their silhouettes as they walked up.

Every drawing was recorded and stored in a database, for content moderation and to play back later in a gallery mode.

My role

I was the main developer on the wall, from the prototype that proved the plexiglass display could work to the software that ran it.

  1. Prototyped the plexiglass-slat screen on a three-foot-square section of the LED wall before the full build
  2. Built the camera tracking that picked up visitors' silhouettes as they approached
  3. Built the drawing tools and the low-res particle system made for the wall's coarse pixels
