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…

They could be intending it merely as an interesting experiment to explore new possibilities for interaction with mobile and wearable tech. Another CS student came up with a virtual keyboard using the iPhone's accelerometer[1]. It only had ~80% accur…

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

Have you tried the Orion SDK? It's an order of magnitude improvement in tracking accuracy, even with the older hardware. https://developer.leapmotion.com/orion

We need to immediately improve on PIN-code protection upon cash-withdrawal in ATMs. The problem has been there for a while, but man, it gets easier and easier.

Or be (not, it would seem) overly paranoid like me, my PIN patterns and entering do not involve moving my fingers horizontally, I put my hand down on the pad with my fingers on set keys, cover it with my wallet, and type it in. I also always double one key to make it that much harder to get by observation, a trick I learned from a sysadmin with major access to my school's systems back when we all had to use public te…

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.

Additionally, a number of these research programs take the source code and make a go of a small business product.

By keeping your fingers longer on the keys you're actually making it easier for the person after you to just take an IR shot of the keyboard and reduce their search space to 16 combinations or less.
