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

www.theverge.com 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 s...

Back on to 3d already? The AI bubble hasn't even popped yet.

Why.

They had this at CES. But the online footage doesn't really capture it very well so I have no idea how good the product is.
If it's pulled off where I suppose it could be useful but it just sort of seems gimmicky to me. Remember 3D TVs, remember how there was absolutely no content for them and no one bought them. Yeah.
- There are plenty of 3D movies still being released on Bluray. And 3D is still a thing in home-theatre projectors. The content is definitely there. And the tech has gotten better aswell. It just never caught on. Because people would rather have 8k on a 30 inch TV.

this was working well in a research lab in the aughts. Surprised its not more common as by now I would think any laptop camera should be able to do eye tracking pretty decently.
- If a 3DS was able to pull this off flawlessly I'm pretty sure any potato laptop or phone can as well.
  The challenge is the display and the software. There is no real contemporary stereoscopy support anymore beyond dedicated VR apps. Nvidia's driver level support has been deprecated, I believe.
  
  that is sad to hear. when it was coming in I just assumed it would be something eventually all cards had as standard.
  
  If a 3DS was able to pull this off flawlessly
  It couldn't...it was highly dependent on viewing angle, both horizontal and vertical, it was really finicky to play 3D games without the 3D illusion dropping because you didn't hold the device in the exactly correct position/angle. On top of that, the 3D looked weird like those old holographic 3D stickers you'd get in breakfast cereal and such. It was a fun gimmick, but it really didn't work all that well.
  
  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.

Woah is that a 3d picture

This will go nowhere.
