Describe the purpose of the non-text object. For example, if an image
performs an action when you click it, describe the action. For a button
that opens your web site, provide a text box labeled "Click to view our
web site".
• If a report includes audio links, provide a transcript for significant audio
clips.
• If a report links to a multimedia or video presentation, provide a transcript.
You may also want to provide captioning for the audio portion and an
audio description of the visual portion. Captioning should be synchronized
with the audio.
Providing text-only alternatives
If there are too many non-text objects on a report, or if you do not have the
resources to integrate accessible design into all of your reports, then you
can provide complete text-only alternatives. For reports that represent data
using only charts and graphics, for example, you can provide a link to a
text-only alternative that provides the same data in data tables and text
objects.
Whenever possible, a text-only alternative should provide the same
information as the original report. The information conveyed through images
in the main report should also be described using text objects on the
alternative report.
Note:
If you cannot produce a complete text-only version of the report, you can still
improve accessibility by providing a descriptive summary of key information
or conclusions illustrated by the report.
It is good practice to provide the text-only alternative on a subreport, linked
from the top left corner of the main report, so the user has the opportunity
to switch to the text-only version as soon as possible. Add the subreport to
the report before any other object to ensure that a screen reader will read it
first. If you want the subreport link to appear only for people using screen
readers or similar software, you can create a subreport link that is the same
color as the background color. The link will appear as a small blank space,
but a screen reader will read the text for the link.
