You can extend this to mechanics/technicians. Manipulating a large screen when your hands are full of grease.

I just spent most of this year rebuilding the engine in my SUV and this would've been an incredible feature. I either greased up my phone when I needed to look something up, or had to take off my latex gloves, which are a pain to get back on when your hands were all sweaty.

but can't the front camera do that with a simple gestures classifier ?

Probably, but that doesn't sell $650 phones

I like the privacy aspect "it's not a camera, it doesn't take picture"

It does send millimetre waves though, could that mean we could hack Soli to view through clothes ? Like a full-body scanner works ?
