Now that&#x27;s a step forward.  Gloves in VR without force feedback have sucked. The insight here is that there are new kinds of gestures, such as touching fingers together and rubbing them sideways. They&#x27;re able to sense those gestures with Doppler radar.  They probably don&#x27;t even try to resolve the gestures into positions; they may just throw a machine learning algorithm at the problem of recognizing the gestures from the Doppler radar outputs.<p>This starts to make VR look useful for something other than roller coaster simulators.<p>Google has a nice demo of a volume control knob. Will this scale up to a virtual mix board?
