Week 5
Building a prototype aural style sheet.
The first step is to determine how successful aural style sheets are in
rendering the audio output of a web page. Theoretically aural styles can
be added to text and other elements of html documents to produce an interesting,
almost human, result. It is anticipated however that practice with lag behind
theory and as with visual styles vary greatly depending on platform and
version of browser.
Adding styles to HTML tags.
Testing Volume.
The following code renders three headings.
<h1>The Best of Janet Jackson</h1>
<h2>Janet Jackson, Design of the Decade</h2>
<h3>1986/1996</h3>
The linked style sheet will render the volumes of the headings
in the following manner.
h1{
volume: 100
}
h2{
volume: 50
}
h3{
volume: 25
}
The first header should be spoken as maximum volume, h2 at medium and h3
softly.
Aural test 1.
Testing Azimuth.
Azimuth is the stereo position of the output.
Styles applied to headers tags above.
h1{
azimuth: center
}
h2{
volume: left
}
h3{
volume: right
}
The output should be center, left and then right.
