People's imaginations have been captured by gesture control since at least the 2000s, when Minority Report and later Iron Man showed characters using it. Today, 23 years after Minority Report's 2002 release, the technology has yet to become ubiquitous. Companies as large as Nintendo, Google and BMW have all launched and rescinded gesture control interfaces that got less than stellar reviews.

That hasn't stopped people from trying. The latest entrant is from Chinese startup Cenwatch, who makes no bones about their influence: Their eponymous device was inspired by, yes, Iron Man.

For form factor they've gone with a watch, with a bulky under-wrist LiDAR scanner. Combined with an inertial measurement unit, this reportedly offers the gesture-tracking accuracy that has stymied other developers.

Here's what they say the thing can do:

I find the design, particularly of the LiDAR scanner, almost shockingly primitive; it doesn't inspire confidence in the product. As usual Kickstarter backers don't share my skepticism, and the $300 devices will start shipping in June.
