Reconfigurable control displays for games, toys, and other applications

This invention describes a control panel system where each physical button or knob has a small display surface in its center. A projector shines changing graphical information onto these surfaces, which a computer controls. The displayed information can dynamically change in response to user commands.

Why it matters: The concept of camera-based input and object tracking for interactive displays, as hinted by the classification, has become far more accessible and powerful since 2012. Advances in compact projectors and real-time machine vision make building such a reconfigurable control system much more practical today.
