We started working on this more since last year (the VR market was slightly better at that time).
One of the differences between this and the existing tech (eg. LeapMotion) is this runs on generic depth/stereo sensors and embedded platforms. So, there is no extra HW needed for many AR headsets with depth sensor already.
We do see many applications for this, but could be wrong. We hope to get your opinion on this.
Here is another demo video showing the accuracy: https://www.youtube.com/watch?v=uBdvL6F0hLE
