Sound and Animation:
Changing a Wiper Blade

The diagram shows the instructions for changing a wiper blade on a motor car. This is all you get: there are no written instructions. You should compare the clarity of the instructions in the diagram with what happens when we add sound and when we animate the diagram.

First, click on the play button on the controller bar to load and play a commentary explaining how to change the wiper. Look at the diagram as you listen to this.You can stop, restart and replay the track by using the control bar.

This second example will load and play a QuickTime video showing a simple animated version of the diagram, accompanied by the commentary.
