Detecting when near limit/s?

[ssstratton]

Hi Everyone
I have been using leap.js through the browser for quite a while (years). There is a repeatable issue with the pinch strength being detected incorrectly when near the limits of the leap motion camera view.

Essentially, the pinch strength will change when a hand goes out of view - probably incorrectly.

Is there a way of knowing when a hand is near the viewing limits? I can easily ignore the pinch strength when near the camera limits... this would also be useful when detecting rotation.

I do know about the interaction box - I don't think this is useful - since it only gives a box location relative to a defined size - this doesn't indicate whether a hand is near the limits of the view.

I have added a check against hand.confidence, but it doesn't seem to be useful - but that could be my understanding...

Best wishes
Andy

There's no established method, but given that the Leap coordinates are in relation to the origin point and the FOV is known to be 150x120, you could have a function that ignores the pinch strength when, say, the index finger's coordinates meet a certain set of value conditions?
