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 parade, but I just don't think they really have anything usable.

I 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.

> implicitly ask them

I think you mean "explicitly"

Earlier quoted context omitted.

How does your phone protect other people from pressing your volume buttons, or using your touchscreen? Security is pretty irrelevant for a HID.

it's obviously pretty different when you don't have to be touching the phone to interact with it

Not when it's a few inches away. It's less distance than voice interaction.
