If the ball has not been seen for a while, nao beginns to search for it in a systematical way. On the screen of the laptop you can see the points of interest marked as red circles. When a point has just been seen its red and gets more transparent with the time it is not seen until it disappears. Thus, the robot can remember the area he already explored.
