Beholder is a CV (computer vision) platform that transforms 2D fiducial markers into a material for physical computing.

We developed a visual design editor that supports people to connect different parameters of these markers (such as presence, position, and rotation) to keyboard input. This enables CV-driven interfaces to control any software that takes keyboard as an input.
