I just came across this, wanted to share it, what do you think? It claims to be the first safe, scalable system for real-time, mid-air, interactive volumetric visuals; no screens, headsets, or enclosures required.

P.S.: Sorry if the submission format is not correct, is my first time publishing.

So it's a laminar flow fogscreen with 3d tracking of digits/inputs? Is this limited to single-viewer perspective then?

99% sure this is not novel (https://www.mdpi.com/2414-4088/7/7/63), but a cool combination of several ideas including tracking the eyes of the user to render content and a more detailed input tracking system. The real innovation here seems to be using multiple projectors vs a single one to get closer to a point-cloud style display.

The demos are cool! Could see entertainment and retail companies buying these if they are assembled into a cabinet, but fogscreens must always be in a dark environment and suffer from poor contrast, inability to black out or provide opaque sections, and always look misty/wavy even with tons of ultrasonic foggers and the laminar correction. If the cabinet controls for these factors and is place in an area with controlled overhead and surrounding lighting it could work.
