What has changed?

It's clearly a much more mature company now, so I'm genuinely curious even if I had reasons to give up on the original device.

The software has gone through two successive generations, each a massive step up from the last.

I suppose I was hoping for a bit more detail than that - are there any key areas where those improvements happened?

Sure! With V2 we saw a more robust and granular hand model, with every finger and joint in the hand being identified. Significantly better performance against ambient light. And huge improvements to how the software handled finger occlusion.

A lot of these improvements were diminished when we went to VR -- new angles, complex backgrounds, different ambient lighting conditions. So we made the Orion software, which was an even bigger step up:

- lower latency

- longer range

- better and faster hand recognition

- vastly improved robustness to cluttered backgrounds and ambient light
