I wonder how accurate it really is. The demo video didn't match up with the movements at all and the on-screen drawings looked like prerecorded video that they were trying to sync to. It's a neat idea, but without a dedicated component or an extremely high-speed RTOS, you're not going to come close to the level accuracy that's really needed to do the math and still allow interaction. I don't mean to rain on the parad…
FingerIO: Using Active Sonar for Fine-Grained Finger Tracking

#32I work with sonar and the physical positioning of the sensors is important in trying to get useful results. Why is it these academic types don't release the apks or software? Just publications and maybe a video.
You should try asking these academic types for the data and source code. A lot of researchers are more than happy to discuss their work, but a big part of the academic industry is your research's impact and references. A way to get a better handle on who is looking at or following on with your work is to implicitly ask them to have a conversation with you before getting the whole kit 'n caboodle.

#35I wonder how much power all the processing draws. Judging from the slow movements and the delayed update on the screens in this video, it's pretty heavy on the processor.
But it's also worth keeping in mind this is all off-the-shelf hardware. It seems very likely to me that if a cell phone or smart watch was designed to do this from the get-go that several easy hardware improvements and maybe a bit of custom DSP work would make this work much better. (By "easy hardware improvements", I mean things like speakers intended to emit frequencies for sonar, microphone arrays intended to receive them, etc.) From that perspective, even if the system we saw is fundamentally limited I'd still call it incredibly promising considering the constraints it is operating under!
If I were a smart watch manufacturer I'd be falling over myself to get one of my best engineers and one of my best recruiters an appointment with these people.

If the tech is great then wonderful, but I still remember LeapMotion...

These sorts of comments are why I come here. Thank you. Without prior awareness that something is common practice it can be extremely difficult to recognize it as an option. I simply lack the motivation for this behavior. If I were to release a teaser about my work it would be because I'm not ready to release my work.
