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.)

<em>I briefly saw a version of this tech demoed on a ThinkBook 16 with a magnetic Magic Bay Dual Camera Concept attached. On the right was a 2D presentation and on the left was a 3D music video playing.</em>
<em>The 3D effect doesn’t show in pictures, but it looked... okay. And looking at the screen off-axis shows some artifacts.</em>
<em>The Magic Bay Dual Camera Concept is a chunky attachment on this sizable laptop.</em>
<em>The Hybrid Dimensional 34-inch Curved Monitor looks like a modded Lenovo Legion Pro 34WD-10 gaming monitor.</em>
<em>The ThinkBook 3D Laptop Concept has the dual camera for head tracking built in. I didn’t get to see this, but here’s Lenovo’s rendering.</em>
