Tutorial: A bird in the hand
Now let's use the gloves to interact with a world. We'll create a duck
and then animate that duck with hand gestures. First comment out the glove
from your script:
##Create a hand object from the data glove
#glove = hand.add(sensor,hand.GLOVE_5DT)
#
##Place the hand in front of the user
#glove.setEuler([0,-90,0])
#viz.MainView.setPosition([0,0.02,-0.4])
Add a duck:
#Add a duck.
duck = viz.add('duck.cfg')
duck.setPosition([0,.5,4])
duck.setEuler([180,0,0])
Now add the highlighted lines to your getGesture() function.
#Add a timer function that pulls the gesture categories from the sensor
#and prints out their labels and moves the duck
def getGesture():
gesture = int(sensor.get()[-1])
gestureText.message(gestureName[gesture])
if gesture == 2:
#Middle finger point
duck.setEuler([1,0,0],viz.REL_PARENT)
if gesture == 8:
#Little finger point
duck.state(1)
if gesture == 9:
#Index and little finger point
duck.state(2)
if gesture == 1:
#Index finger point
duck.setPosition([0,.05,0], viz.REL_PARENT)
if gesture == 0:
#Fist
duck.setPosition([0,-.05,0], viz.REL_PARENT)
vizact.ontimer(0, getGesture)
Run the script and try playing with the glove. Point with your index
and little finger to get the duck jumping, point with your little finger
to make it walk, point with your index finger to make it rise, make a
fist to make it fall, and point with your middle finger to make it spin.
