While the first two attempts fail quickly, the last attempt seems to succeed. Eventually a prince comes along and by coincidence Snow White awakes from her death-like sleep. Snow White and the prince fall in love and live happily ever after. Figure 7.4 shows the main cast of the story. In the following sections various interfaces of the prototype are discussed.
Time starts at the left side and ends at the right side of the slider.
Two arrow buttons allow to step through the story frame by frame. The slider also gives the user visual feedback about the current location in time. The button changes its appearance according to the action which is executed when the button will be pressed. When clicking on an object a popup window with four controls appear, see Figure 7.6 . The top left button expands the marked object, the button in the bottom left condenses the marked object.
