Lenovo is testing glasses-free computers with a ring controller.

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

    Oh, now you are objectively incorrect.

    I pulled mine out on the back of this thread (not hard, I have it on hand), just to reassure myself of how effective the eye tracking is. A level of Yoshi’s Wooly world later, I can say it only lost tracking when I started pacing around with it. While sitting or standing with it in my hands it was just a clean, solid 3D image, and it definitely beats having some polarized or shutter glasses on my face.

      You are objectively incorrect. The tracking is better, yes, but the image is blurry when 3D is on. It’s definitely not clean and solid.

        I will choose to believe my eyeballs on that count, but thanks for your contribution, I suppose?

        This is a real issue with stereoscopy, in that it’s hard to talk about and there isn’t a guarantee that people’s perception of it is identical. Here, for example, I don’t know what you mean by “blurry”.

        Potentially you could be talking about the ghosting effect you see when the lenses aren’t properly lined up with your eyes. I find that is entirely resolved by the eye tracking unless you’re moving the console around on the what, three different New 3DSs I have used for any length of time. I can’t guarantee something about your eyes or your 3DS isn’t different, though. I can only tell you I have a 3DS in front of me right now and I’m tilting it every which way and I see no ghosting as long as the camera gets line of sight to my face.

        Or you could be talking about resolution. Because the way 3DS stereoscopy works is by angling alternate lines of pixels to each eye there is a horizontal resolution change on the display between 2D and 3D, although your brain should sort most of it out when overlapping the two images. I’m sitting here with a 3DS in front of me typing this and flipping the slider on and off and the image doesn’t lose any resolution to my eyes, it just goes deep. Can I promise that your brain is parsing the half-res-per-eye the same way mine does? I guess not.

        All I can tell you is the effect is rock solid for me and I would take it on a tablet or laptop any day with no improvements (although I’d like to see how much further it can be pushed with modern tech). This is non-negotiable and the results of real life testing in real time right the heck now. Unfortunately for the same reason I can also not sit here and tell you that you aren’t seeing what you’re seeing. I can only report on what I see.
