Usefulness of ALT Text
Page with images not

Images from BBC
Pick the Best Two ALT Tags
Context: 6 Nationalities of Texas
1. Wow, Six flags over Texas!

4. Photo shows flags of Spain, US, Mexico,
France, Republic of Texas and
Confederate flag

Full Image of Six Flags
Complex Images
Too complex for an ALT tag
Describe in main text and use short ALT text
Colonial New Netherland stretched
from New York City (New
Amsterdam) up Hudson River
Valley to north of Ft. Orange
(modern Albany)
Colonial New Sweden was
centered on the Delaware river
and stretched from the head of the
bay to a little south of Trenton.

Unclear Link Text
Avoid
For more information about accessibility, click here
Or learn more here, here and here
“Learn about additional international resources that might
be useful in class or in research”
Blocker because
Screen readers search for/scroll through links
“Here” is small (hard to find) and ambiguous
Try This
You can get more information from Accessibility at Penn
State
Learn more from “International Music Links”

Tables: Simple vs Complex
Simple Tables
Have no merged cells or empty cells
Rows represent one type of data
Columns represent another type of data
Are easier to accessify
Are easier for screen readers to process
Complex Tables
Are popular, but not always user friendly
Tricky to maintain
Often based on layout from print sources
We have different options on the Web!
Well Marked Data Table
CAPTION
“Windows ALT
Code for Currency
Symbols”
TH = Table Header
1st row
1st column
Headers allow
screen readers to
match cell with
row, column
ANGEL Table Tools
Allows you to add caption, headers,
summary (invisible, but read on screen
reader)

Color Contrast (Luminosity)
Affects low vision, color deficient
Not too vivid or too bright
But not too subtle or too light either
Like medium red, dark gray, dark teal on white
Avoid orange/yellow and white
Use with black instead

Supplement Color Coding
Use color coding, but
make sure it’s OK in black
and white
Green check & red X
Labels in or near colored areas
Red-blue safer than red-green

Select Question page
Radio Button: Accessible and Usable
Found in Multiple Choice, True/False
Highly accessible
The radio button is easy to select
gives the user the option to select before and after the
question.
http://accessibility.psu.edu/angel#quiz
Multiple Select Questions:
Accessible and Usable
Check boxes are provided that have the
same beneficial functions the Radio Button;
before and after selection!
Specify “Check all that apply”
Combo box Popup:
Accessible BUT NOT Usable
Combo box popup
The selection boxes do NOT repeat after the question.
Multiple selecting required.
One to select the pop up.
Second to select a choice.
The alphabetical bulleting is automatically formatted even though the
combo box popup is numerical selections for ordering questions.
Choices can be selected more than once.
Matching: Accessible, NOT Usable
Requires a tabular list of information above.
Long list of choices maybe cognitively challenging
on short-term memory.
Ordering;
Accessible, NOT Usable
Ordering
Issues
Combo box popups in ordering
questions use numerical selection and is
associated with an alphabetical order in
ANGEL.
The task is NOT explained in context of
the selection tool.
The same number can be selected
twice.
Difficult to navigate back to change an
answer.
Re-worded Ordering Questions
Explain the task
Limit the number of items to be ordered.
Combo popup boxes still NOT user friendly.
Use Multiple Choice version of question.
Still difficult to navigate to change answers
Multiple selecting process
Multiple Choice Alternate for
Ordering
Worst version
More usable multiple choice
Fill-in-the-Blank:
Accessible and can be Usable
Potential Gotchas
The task maybe unclear.
The blank space requires filling-in before the context of the
sentence is understood.
Navigating back to the blank space is difficult.
The Usable and Accessible
Fill-in-the-Blank
Provides the user to hear the entire sentence first
before inputting the answer.
Allows the user to hear the entire paragraph before
entering the answer.
Using a word bank? Identify them and place them
before the paragraph.
How to write a Fill-in-theBlank/Cloze
Use _1_ to control position first
blank
Then _2_, _3_...
NOT Accessible
Games/Flash
Games =
Crossword Puzzle,
Quiz Show
