Interactive WWW Documents.

The W3 browser parses a WWW document before displaying it. Emacspeak relies on this internal representation to provide the spoken rendering, rather than examining the visually displayed document. This fits well with the overall design of Emacspeak; it also enables Emacspeak to produce spoken feedback that would be impossible to generate by merely examining the screen.

A typical interaction with a form element consists of:

• Moving system focus to the element.
• Changing the state of the form element, e.g., pressing a button or entering a value.
• Obtaining confirmation from the system about the recently performed action.

We illustrate this with examples of what happens when the user interacts with different form elements that are found on WWW documents.

Text Field

• Emacspeak summarizes the element under the focus with an utterance of the form ``text field field name set to value.''. The name of the text field and its value if any are retrieved from the internal representation.
• Pressing enter results in the spoken prompt ``Enter value for field name.''.
• After the value has been input, Emacspeak confirms this with the announcement ``text field field name set to value.''.

Check Box

• Emacspeak summarizes the check box with an utterance of the form ``Check-box name is checked.'', assuming the box has been previously checked.

• Pressing enter produces a button click.

• Emacspeak says ``unchecked check box name.''.

Radio Button

The interaction parallels that described above for check boxes. The utterance uses the phrase ``is pressed'' to distinguish radio buttons from check boxes.
