Leap Motion Swipe Gesture Detects More Than One Swipe

[teddiesaurus]

Hi,

I'm developing a project using Leap Motion and Processing using this Leap Motion for Processing plugin.

When I use the SwipeGesture function, a single swipe motion detects multiple swipe gesture. Is there any way to make the function only detects 1 swipe gesture in a single swipe?

Regards.

The swipe gesture is being picked up for each finger. If you limit detection to a single finger (e.g. the index finger), you'll be all set.

Hi,

Thank you for your reply.

I have tried limit the detection to a single finger. It works. But it detects several swipes intermittently. Any idea?

Regards.

You may need to set a condition where once a single swipe is registered, no further swipes are recognized after a certain period of time.

@AlexColgan @teddiesaurus thanks for your message,
I would like to trigger deterministic right/left swipe (only) but I get good detection for up/down swipe detection but this is not triggering very efficiently (i.e. I might swipe the hand and not get triggering). The code is in python

(...)
for gesture in frame.gestures():
if gesture.type == Leap.Gesture.TYPE_SWIPE:
swipe = SwipeGesture(gesture)
if (swipe.direction.x < 0 and math.fabs(swipe.direction.y) < 5):
print "Swiped Right" + str(swipe.id)
return len(frame.fingers.extended()), 0, 0, 2
elif (swipe.direction.x > 0 and math.fabs(swipe.direction.y) < 5):
print "Swiped Left"
return len(frame.fingers.extended()), 0, 1, 3

Could you help me to have a more deterministic right/left swipe detection ?
Cheers
