Nice article, FYI you could use sqrmagnitude rather than distance to squeeze out some more perf.

Could you explain the values returned by CalculateIndexPinch() and FingerCurl()?

[LocalJoost]

Well - it's both a value between 0 and 1. For curl, 0 in not curled, 1 is as far as it will curl. For pinch, I assume the certainty that a pinch is detected. My threshold values are just empiric - that's a posh word for 'I found this out by trial and error'. Does that answer your question?

@SimonStHilaire you are welcome and thanks. It's nice to hear my blog is not just me shouting into the void ;)

Hi Joost. Thanks a lot for the blog post and it helps me a lot! I am just wondering, do you think it is possible to detect more complex hand gestures, such as a heart shape or a victory shape, with your approach? I know probably there are methods using CV to do so, but I am trying to look for some comparisons of different approaches in terms of speed and accuracy.

[LocalJoost]

Hi @PepperXu , I am not sure, I think you are pretty much on your own here. You might try some algorithmic approach based upon relative position of fingers in a pose, but AFAIK there is nothing out of the box or some code that I am aware of

Hi @LocalJoost I was wondering if you have tried this with MRTK3. Thanks.

[LocalJoost]

Not yet.
