gesture

gesture library will detect your gesture by using webcam, you can call a function when a gesture (left, right, up or down) is detected.

Functions

• gesture.start(): Start webcam and detecting gesture
• gesture.stop(): Stop webcam
• gesture.on(dir, func): Set callback function for dir, when dir is detected, this function will be called. dir 's value could be left, right, up and down. If you didn't use this on function to set callback function, by default, if left is detected, function gestureOnLeft will be called (if defined); if right is detected, function gestureOnRight will be called (if defined); if up is detected, function gestureOnUp will be called (if defined); if down is detected, function gestureOnDown will be called (if defined).

Example

import gesture

def on_left():
    print "moving left"

def on_right():
    print "moving right"

def gestureOnUp():
    # this is the default callback function when `up` is detected
    # you can use gesture.on('up', other_func) to set this callback
    # function to be other_func
    print "moving up"

def gestureOnDown():
    print "moving down"


# set callback function for left and right gesture
gesture.on("left", on_left)
gesture.on("right", on_right)

# start webcam and detecting
gesture.start()
