                     VIDEO SENSING

                     The Video Sensing extension lets you use your webcam
                     to control your project. It can detect movement in front

                     of the camera and use it to make things happen in the
                     game, like moving a sprite or triggering an action.

                     The Video Sensing  extension  includes  the  following

                     blocks:

                                                               It  starts  a  script  when the  camera  detects
                                     when video motion  >  10  motion  greater  than a set  value (like  waving
                                                               your hand).

                                                               This block  detects  the motion  or direction  of

                                video  motion  on  sprite      movement captured by the webcam. You can
                                                               apply it to a specific sprite or the entire stage.

                                                               This block turns the webcam on, off or flips the
                                           turn video  on
                                                               video feed.

                                                                                                    Scratch Meets AI   115
