Lenovo is testing glasses-free 2D / 3D computers with a ring controller.

Lenovo’s new ThinkBook 3D Laptop Concept and Hybrid Dimensional 34-inch Curved Monitor, announced at MWC 2025, use directional backlighting and head tracking to simultaneously show 2D and 3D content without glasses. And an accompanying AI Ring concept can be worn to control them with gesture-based spatial controls. It sounds like Leia’s tech, but in my short demo Lenovo reps would not confirm. Maybe 3D is coming back? (I doubt it.)

    Firstly the 3DS couldn’t pull it off. Secondly this is a completely different technology. Basically it’s just tracking your eyes and Parallax mapping the screen effects.

    It’s still a 2D display in reality.

      Yeah, no, the 3DS did eye tracking starting with the New 3DS.

      Have people memory holed this? The New 3DS could adjust its parallax via eye tracking to a much wider effective tracking angle. It took a fraction of a second to adjust if you moved too quickly, but it was seamsless most of the time.

        I have no idea what you mean. I’ve never heard of a new 3DS when did it come out?

          1. It had a bigger screen, eye tracking for the stereo 3D, a built-in second stick nub thingy and a bit more performance. It came in two sizes, to match the OG and XL versions of the base model.

          Kinda nuts that this fell through the cracks for some people. The improvements to the stereo tracking were dramatic.

      im not sure how the 3ds did it but if this is what I think the screen will still require physical lines to work off of that will be so thing that they should barely be visible or assuming its done better two screens on top of each other where the first screen throws up the lines and could likely be something like eink.
