equivalent. Adding text descriptions for decorative objects can produce
unnecessary clutter.
Text versions of visual or auditory objects in reports should be used as a
complement to the object—not as a replacement. You do not need to remove
non-text objects. Visual objects in reports can be very helpful, especially for
people with learning disabilities such as attention deficit disorder, or for people
who are deaf. People with hearing impairments may be accustomed to visual
communication such as sign language, and may find images more useful
than text.
No one presentation method can meet the needs of all users. Audio clips
can be very useful for people with visual impairments, but people with hearing
impairments will be unable to use them. To help both groups, provide a
combination of audio and text. Multimedia presentations may provide audio
information for people with visual impairments, as well as video information
for people who are deaf or hard of hearing. Multimedia presentations are
particularly effective for people with attention deficit disorder. However, people
with certain mental health disabilities may be distracted by visual or audio
objects.
The best approach is to communicate the same information with both text
and non-text objects. Add descriptive text to support the images, and add
images that support the text.
If text objects begin to overwhelm your report, you may want to provide a
complete text-only version in a separate report or a subreport. For details,

Color
The colors you choose for objects in reports can have a significant impact
on accessibility for people with visual impairments, low vision, or color
blindness. Ensure that your reports can be understood when viewed without
color.
