We tried to schedule some meetings with them a few years ago, but after some back and forth they were difficult to deal with. In any case, prior to the meeting I had done some preliminary research, there is other interesting research in the area Here's a video of tracking using, if I recall, a fairly cheap camera - https://youtu.be/kuaMcVf501Y?t=4 https://youtu.be/kuaMcVf501Y?t=4 And here's one of the associated papers - http://cdcl.umd.edu/papers/rsi2012.pdf http://cdcl.umd.edu/papers/rsi2012.pdf This paper in particular is interesting because, at the time I was working with an optics expert, and one of the major limitations at the consumer level was what this new paper aims to addresses (power output and safety). One observation we made was that, for consumers there are not too many laser 'things' in the home that are not fully enclosed. Basically, the FDA takes laser safety extremely seriously. People often think only about looking directly into a laser, but backscatter can also be dangerous.
