These methods vary according to factors such as the design of the tool and the user interface conventions for its platform. The following is relatively generic overview of how these methods can be used for accessibility prompting. Prompts Prompts are basically requests for information. On most GUI platforms prompts take the form of dialog boxes that request information from the user. For example, a text equivalent entry field prominently displayed in an image insertion dialog would constitute a prompt.
Prompts are relatively unintrusive and address a problem before it arises.
However, once the author has ignored the prompt, its message is unavailable. In the example below, Allaire Homesite prompts the user to enter Alt. Text by including this property within dialog that is displayed during image insertion. Although the dialog itself is in some sense intrusive, the inclusion of the Alt. Text field, once the dialog is displayed, would not be considered intrusive.
