ABSTRACT
What are forms? Before looking at the dierent settings in which forms are used, we need to dene what a form is. Even if forms are ubiquitous and we recognize a form when we see one, how do we dene what a form is? A benet claim sheet is clearly a form, but what about a bill? I prefer a broad denition, as I think it is not so much the visual appearance of a form that makes a form, but the way the information is gathered and presented. This is why I count everything as a form which matches the following two criteria: • A form is a means for two-way communication. • A form includes a xed part (e.g. questions and prompts) and
a variable part (e.g. check boxes and blank input elds).
