ALT Tag/Text/Attribute

Text which replaces image if it can’t be processedALT=“Washington at Valley Forge in

winter snow”Appears when image fails to load

Image fromWikipedia

Adding ALT Text Add “Short Description”

or “Alternative Text” when inserting image.

Usefulness of ALT Text

Page with images not loaded and missing ALT text

Images from BBC

Pick the Best Two ALT Tags

Context: 6 Nationalities of Texas1. Wow, Six flags over Texas!2. Image taken from Wikipedia. Photo by

Ann W.3. 220px_Six_flags_over_Texas.jpg4. Photo shows flags of Spain, US, Mexico,

France, Republic of Texas and Confederate flag

5. Photo of six flags read information below6. Photo shows 6 flags of different colors

waving in the breeze on a sunny day. Three are red, white and blue….

Full Image of Six Flags

Complex ImagesToo 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 TextAvoid

“Learn about additional international resources that might be useful in class or in research”

Blocker becauseScreen readers search for/scroll through links“Here” is small (hard to find) and ambiguous

This strategy works across all tools!

Scanning Links on a Screen Reader

Headings on a Page Wikipedia article using subheadings to mark topic changes

Tables: Simple vs ComplexSimple Tables

Have no merged cells or empty cellsRows represent one type of dataColumns represent another type of dataAre easier to accessifyAre easier for screen readers to process

Complex TablesAre popular, but not always user friendlyTricky to maintain Often based on layout from print sources

We have different options on the Web!

Well Marked Data TableCAPTION

“Windows ALT Code for Currency Symbols”

TH = Table Header1st row1st columnHeaders 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)

Not too vivid or too bright

But not too subtle or too light eitherLike medium red, dark gray, dark teal on

ANGEL Select Question page

Radio Button: Accessible and Usable Found in Multiple Choice, True/False

Highly accessibleThe radio button is easy to selectgives 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 answersMultiple selecting process

Multiple Choice Alternate for OrderingWorst version

More usable multiple choice

Fill-in-the-Blank: Accessible and can be Usable

Potential GotchasThe 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 AccessibleFill-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-the-Blank/Cloze
