Blocks style "raise hands" gesture

[robertwilde]

Hi,

Blocks features a couple of gestures: wave, thumbs up, pinch, raise hands, lower hands.
With Orion Core 4.4.0 and InteractionEngine 1.2.0, how would I go about implementing the "raise hands" gesture?
Any ideas? I have no real starting point whatsoever.

Kind regards,
Rob

Check out our Unity documentation; the Core Assets have detectors for things like palm up: https://leapmotion.github.io/UnityModules/class_leap_1_1_unity_1_1_palm_direction_detector.html

You can combine a few tracked hand characteristics to make a "recipe" for the raise gesture.

Thanks!

I got a detector now for the palm positions: up, down, in, out, forward, backward.
I'm doing the palm direction detection based on the palm Z axis, the view forward, up, right axes, and the dot product between them. This seems to give me more flexibility than the PalmDirectionDetector.

Now I need to detect the gesture itself. Somehow that both hands with palm pointing up have moved vertically?

I'm now able to detect the gesture "as it happens". Basically on every Update I'm able to raise a Swiping event, e.g. swiping left, swiping right, up, down. I might do a OnSwipeBegin, OnSwiping, OnSwipeEnd event structure. Not really happy with that, but it's good enough for now.
