Abstract
We present how to retrofit an interactive tutorial program onto an already completed web application program by taking the example of IslayTab, a graphical programming environment for children, which can be manipulated only by tapping on a tablet device. The tutorial program prompts the user to tap a single specific DOM node of the original application by highlighting it in front of an additional DOM node in the form of a translucent gray sheet that shades the other DOM nodes. Any user events on wrong parts are caught by the gray sheet and cause repeated prompting. When the user taps the expected DOM node, the process originally assigned to this DOM node is naturally activated. The tutorial program does not have to take any care of processes in the original application and only has to check if the user event took place at the expected DOM node in order to proceed to the next step of the tutorial scenario.
