The makers of Lightform call it “the first computer made for projected augmented reality.”

Lightform scans complex scenes in under a minute, letting you seamlessly mix real objects with projected light. It’s augmented reality without the headset.

Check out a demo made with it & read more on Wired:

The small box contains a processor and a high-res camera. Hook it up to any projector through an HDMI cable, and the projector will cast a series of grids onto the room, which Lightform’s onboard camera uses to assess, in fine detail, the location and dimensions of objects in the space. (Lightform can also scan the room periodically, allowing it to create a new map if anything moves.) The processor converts that information into a 3-D map of surfaces onto which the projector can cast light. […]

In other words: Lightform helps you quickly transform almost anything in a room into a screen
