This resonated most with me: the idea of everything becoming a display and control surface. From the folding panel in the foreground to the entire wall in the background, whatever makes contextual and use-mode sense.
It was pretty home-brewed at this point, but the idea of a wall having a full array of images and touch points projected on it starts to connect the dots for the smart home we're still waiting for. I just don't know how we'll cost-effectively get big images on walls without projection we're always standing in the way of.
I've seen these real-time avatar demos before and they always make people cringe! Here you stand in front of cams and sensors and can try on different clothes, but the imaging has a long way to go...still.
This technology got my mental vote for "Most Ready to Hit the Market Successfully." This electromechanical beam-stuttering technology really made a big visible difference in the amount of light reflected back at the demo headlights. I could see carmakers getting serious about this, especially coupled with their existing night vision technologies.
