Here are my notes from this week, from the course:
Digital Media Categories
- Text
- Images
- Audio
- Video
- Complex
With any digital media, it is always important to understand
the playback context the student will open the content in.
Following is a table of basic access strategies for these
media types.
Media Type
|
Access Strategy
|
Text
|
Generally
accessible to most assistive technologies such as screen readers and
electronic reading systems.
|
Images
|
Provide
a textual equivalent that can be rendered into an accessible format via
assistive technology for non-sighted viewers.
|
Audio
|
Provide
a text transcript of the audio information that can be rendered into an
accessible format via Assistive Technology for non-sighted viewers.
|
Video
|
Captioning
should be put in place (open or closed) in order to provide an equivalent
experience for individuals who are unable to hear the audio content.
|
Complex
|
Complex
media containing other media types (text, images, audio, and video) must
begin with the best practices for accessibility in each of the included media
types. In addition, appropriate markup of headings and other content must be
applied to the different media constructs throughout the media file. By
applying appropriate markup and definition to content, assistive technologies
can better process and interact with the material.
|
There is a range of accessibility and usability potential
among the digital text flavors, running from simple to powerful. Starting with Plain
Text (.txt), which is quite literally, plain text with no
formatting, moving to Rich Text Format (.rtf) documents, spanning
proprietary document formats like Microsoft Word (.doc or .docx) and
InDesign (.indd), etc., and ending up with the ever common HTML (.htm or
.html) and PDF (.pdf).
Digital Text Formats in Order of Potential Usability:
- HTML
- RTF
- TXT
Digital Text Formats in Order of Intrinsic Accessibility:
- TXT
- RTF
- HTML
Proprietary Issues
There are many digital file formats that use digital text,
but not all file formats will open interchangeably without owning the proper
application. Because of this, a key consideration is to use a non-proprietary
file format or ensure that the necessary technology to open the file is also
available to the student.
Of all the digital text formats, properly formatted HTML
provides a high level of access and usability while being freely distributable
and easily viewed by many freely available applications.
Images
--
in the case of images that contain information significant to the instruction,
you will need to provide a textual description of the content.
Containing the Image
Whatever the ultimate purpose and instructional value of an
image may be, most of the time images will be contained in some sort of
document file. Depending on the document format, you may be able to associate a
text description of the information directly into the image. Sometimes you will
need to place the textual description in the document either before or after
the image, or as an image caption.
The relationship between digital images and the documents
they are contained in is important to understand. Most digital image files do
not allow you to embed textual information inside the image file. Typically,
when you place the digital image into an electronic document, the electronic
document will provide some means of associating a textual description with the
image. However, if you use that image in another document or different document
format, you will likely have to re-associate a textual description with the
image in the new document format. This is because the textual information is
only associated within the context of the bigger digital document. The
individual digital image file remains a separate entity from the associated
text. For example, in a Web page, the “alt” tag is used to describe the content
of an image, but the “alt” tag is part of the Web page , not part of the image.
In the above image, the alternate text given is
"relationship between alt text and image within a document". This
description effectively conveys the message contained in the image. Note that
the complex details are not mentioned, as the concepts they are explaining have
already been presented in the preceding text.
As part of the range of content that can be contained in an
image, you will find digital images of textual information, but this is not the
same as digital text. A quick and easy way to check if you’re dealing with
digital text or a digital image of text is to try and select the text on your
screen and copy it to a word processor or text editor. If you can copy the text
into the word processor or text editor, you’re dealing with digital text. If
you can’t copy the text, you may be dealing with an image of text.
There are computer programs that can try to determine what
the actual text is inside a digital image, these programs are known as Optical
Character Recognition (OCR) programs. When you use an OCR program on
digital text, it will save the resulting digital text as a text file (.txt,
.rtf, .doc, .html, etc.)
Until computers are able to look at an image and
automatically determine the content, providing an effective text description
for images is vital to ensuring accessibility and usability of that digital
image.
Audio
Digital audio can be stored in several different formats,
and with a wide variety of quality and file size. Regardless of the specific
digital audio format used, the strategy for providing access remains the same:
provide a transcript.
Unlike digital image files, certain audio file formats will
allow you to permanently associate textual information with the audio content.
In this way, the audio file always has the textual description included no
matter where you copy or move the file. There is an important limitation,
however, as the playback device or software must provide a method for viewing
the textual description.
Some common audio files that support the permanent
association of textual descriptions are MP3 (.mp3), MP4 (.mp4), Apple Audio
Codec (.aac), Quicktime Audio (.mov), and the Apple proprietary formats (.m4a,
.m4b, .m4v). It is important to know which file format your audio information
is in, and how to associate textual information with that file.
Even if you embed the transcript of an audio file in the
meta-information (ID3 tags) of that digital file, you should also provide the
text transcript as a separate download. If a student is completely deaf (as
opposed to having a degree of partial hearing loss) they may prefer to only
have to download the smaller text file rather than the much larger audio file
where the transcript is embedded in the ID3 tags.
Remember that producing good quality recordings can also
help increase the accessibility and usability of audio files for individuals
who are hard of hearing. If the overall quality of an audio recording is poor,
AT will have an even more difficult time with the information.
Video
Digital video information typically includes audio, which
again needs to be transcribed. However, because it is video, the text
transcript must be delivered synchronously with the corresponding dialogue as
it is spoken on screen. This is called captioning, and it comes in two flavors:
open and closed.
Closed Captions are
the captions that you can turn on and off, assuming that you know how to work
your television’s remote control.
Open Captions are
the captions that are permanently turned on, similar to foreign language subtitles.
There is an important distinction between captions and
subtitles: subtitles provide a translation of dialogue, while captions provide
a textual indication of all significant audio information, including sound
effects and music. For accessibility concerns, subtitles are not equivalent to
captions because subtitles do not convey all of the significant audio
information of the video.

Today there is a small pool of digital video file formats
commonly in use that allow for captioning. They are Quicktime Movie (.mov),
MPEG (.mpg or .mpeg), AVI (.avi), Flash Video (.flv or .swf), Windows Media
(.wmv or .asx) and Real Player Media (.rpm)
Complex Digital Media
Complex media refers to those digital media formats and
systems that can contain multiple media types at the same time, and/or provide
means for user interaction with the content.
Complex media can be a single digital file or a system that
coordinates multiple digital files being exchanged between the instructor and
students. HTML and PDF files are common examples of complex media files that
can support a variety of different media types. Learning Management systems
such as Moodle or Blackboard are examples of complex media delivery systems,
providing a variety of ways to organize and deliver digital content and
offering multiple methods for interaction with the content and other users.
Typically, complex digital media is an assemblage of
discreet media files such as text, images, audio, and video. By following the
best practices for creating these individual digital files, you can help ensure
the accessibility and usability of the information when it is presented as part
of a complex document or digital media system. In addition, it is important to
become familiar with any built-in accessibility tools that are included in
whatever complex media file format or system you use.
In addition to ensuring the accessibility of the discreet
media assets used in a complex media file or system, it is critical to ensure
accessibility of the various interactive aspects to ensure that they are
compatible with different AT.
Relative to Distance Education, AT typically refers to a
range of technology used for communication and cognition. As technology is
often a determining factor in how distance education is designed and delivered,
it is critical to ensure accessible technology is compatible with instructional
technology and media.
Many forms of AT deliver a specific format of media, or "alternate media" to an individual with a disability. Alternate media is any form of media that is appropriate and effective in communicating with a specific sensory ability. Many forms of modern media such as MP3’s and HTML pages become “Alternate Media” specifically when used by individuals with disabilities. One of the key aspects of understanding alternate media is separating the message or content from the mode of presentation or specific media form. This means you create one piece of content that can be used by multiple forms of AT.

One of the ultimate goals in designing accessible instructional materials is to provide the end user with the ability to effectively control and customize the presentation of information. The ultimate realization of this concept is a single electronic document that can be presented through any interface the student might choose (or require). By defining content with consistent logical and navigational structures such as headings and page numbers, you allow content to be consistently and accurately rendered on a variety of interfaces. This allows for the end user to have control over the various nuances of their specific interface without the author having to anticipate every possible technology that might be used to view the content.
Principles of Universal Design
The concept of
one source document that can be accessed by all forms of assistive technology
and automatically converted into an accessible format needed by the recipient
is sometimes referred to as “Universal Design for Learning” or “UDL”, borrowing
from the architectural concept of Universal Design. While the overall concepts
of Universal Design are admirable, within the context of designing accessible
online courses, it can sometimes be more helpful to think in terms of
“Universal Compatibility”. The idea of creating a document that can be
everything to all users can be a bit overwhelming, but perhaps it is a little
less intimidating to create a document wherein the material has the appropriate
structure for assistive technology to snap onto. Ensuring that instructional
technology and media is able to interface with assistive technologies is the
primary focus of creating accessible web-based instruction.
Assistive Technologies
Following is a list of common
categories of AT. It is important to recognize that this list is just a
starting point, as the ultimate range of assistive technologies is as varied as
the range of disabilities.
·
Screen Readers: Typically used by
individuals who are blind, screen readers are intended to provide visual
information as audio information (sound). This is not altogether difficult in
and of itself, but challenges can arise when screen readers are faced with
certain types of content; also used to control Refreshable Braille Displays,
which allow for dynamic representations of Braille characters through tiny
mechanical pins aligned in a long strip.
·
Screen Magnifiers: provide an enlarged
view of the computer display; Closed Circuit
TeleVision (CCTV) systems provide a means for enlarging non-electronic
information, and in some cases, provide limited means for altering the display
characteristics to improve legibility for certain visual disabilities.
·
Speech Recognition: spoken dialogue is
analyzed and converted into digital text.
·
Closed Captioning Decoders: essential element in
displaying traditional analog broadcast captions, often referred to as
“Line-21” captions. Whatever the underlying technology may be, the concept is
the same: present a synchronized text version of the spoken dialogue and
meaningful audio content.
·
Alternative Keyboard Access: specialized switches
and software that provide better control for individuals with various
disabilities. Sometimes these solutions are just physically adapted keyboards,
and sometimes they are limited switches with software-driven routines to
provide the full range of key options available through a traditional “QWERTY”
keyboard
·
Refreshable Braille Displays: system of presenting
computer information as Braille code. Using a series of plastic pins, different
Braille characters can be presented dynamically to allow the information from a
computer display to be rendered as Braille information
·
Reading Systems: present visual
information as auditory information, as well as providing a means to alter and
customize the visual appearance of electronic information. Common features of
reading systems include an ability to visually highlight words as they are
being read aloud, as well as the ability to enlarge and change text fonts and
document colors. Some reading systems include dictionaries, homonym checkers,
and word prediction functions. Mind mapping and critical thinking tools are
also provided in some reading systems.
Disabilities and related forms of
Alternate Media and Assistive Technologies
Recognizing that both human difference and technological innovation contribute to the dynamic nature of AT, the lines can blur between categories of AT, and sometimes technologies are abandoned as newer and more effective technologies are developed. In addition, often individuals will have multiple disabilities that require combinations of AT and alternate media.
Here are some common disability types with corresponding examples of common AT and alternate media accommodations:

Here are some common disability types with corresponding examples of common AT and alternate media accommodations:
·
Blindness: Screen Readers, Refreshable Braille Displays, DAISY,
Braille, Books on Tape, Audio CDs, MP3s, Digital Note-taking
·
Low Vision: Screen Readers, Screen Magnifiers, Large Print, DAISY,
MP3s, Audio CDs

Devices, Closed Captioning, ASL, Remote Captioning, Remote Video Interpreting,
Text Transcripts, Digital Note-taking
·
Mobility
Impairment: Speech Recognition, Specialized
Keyboards, Alternate Switching Systems, Word Prediction Software, Custom
Interface Modifications
·
Learning
Disabilities: Reading Systems and Study Tools,
which typically provide some sort of audio and visual reinforcement,
separation, synchronization, and layout alteration. Other common study tools
provide word prediction, and features for organization and outlining
information.To see how reading can be affected by Dyxlexia see http://www.readregular.com/english/dyslexia.html (opens in new window).
Alternate media is
an alternative medium of presentation from that in which the work was
originally done. A regular hard-copy book, for instance, may be converted into
an electronic (e-text) book. E-text is words (text) that a computer can read.
E-text is the basis for all alternate media formats.
The Office for Civil Rights (sometimes abbreviated OCR) has determined that there are three important criteria for providing accommodations to students with disabilities:
The Office for Civil Rights (sometimes abbreviated OCR) has determined that there are three important criteria for providing accommodations to students with disabilities:
·
timeliness of delivery
·
accuracy of the translation
·
provision in a manner and medium
appropriate to the significance of the message and the abilities of the
individual with the disability
·
Electronic Text
(Etext)
·
HTML, ASCII, MS
Word, RTF
Digital or Electronic Text (Etext)
is the category of media comprised of simple text. While some digital media
formats such as HTML or MS Word documents can also contain images and sound
files (among others), they are also representative of the first level of
technical access for electronic information.
·
Large Print
Large print is a category of print
larger than the standard printed addition. While this definition is somewhat
arbitrary, most body type set as larger than 14 pts is considered to be “Large
Print,” though typically the value is closer to 18 or 20 pts. However,
sometimes large print is created in much larger sizes. As one of the least
sophisticated visual accommodations to use, large print is a very common form
of alternate media for older individuals dealing with sudden degenerative
vision loss
·
Braille
Created in the mid-1800s and named
after its inventor Louis Braille, braille is a code for tactile reading and
writing, used by individuals who are blind. Based on a six-dot pattern
that was designed to fit under an individual's finger-tips, braille characters
are used to transcribe words, numbers, characters, and symbols. Since braille
only contains 63 symbols, there are extensive rules, known as braille
"codes," that assign different meanings to the same braille symbols,
depending on when and how the symbols are used. Special braille codes are used
for complex information such as math, science, and music. Braille can be
embossed onto paper or rendered via refreshable braille displays to display
digital information.
Closed Captions (CC)
Closed Captions are the textual transcripts of spoken
dialogue and significant auditory information in video and film media. A
variety of technologies are used to create and present closed captions,
depending on the specific visual media being used. There is also a significant
difference between Closed Captions and Subtitles, as Subtitles only present
textual equivalents of spoken dialogue, whereas Closed Captions provide a
textual equivalent for all meaningful audio information. Closed Captions are
different from Open Captions in that Closed Captions can be turned on or off by
the person watching the visual information. Open Captions, like traditional
subtitles, cannot be turned off by the person watching the visual information,
and are always onscreen.
MP3s and Other Audio Files
WAV and MP3 are file formats for audio information. MP3 is a
smaller (more compressed) format, which is why it has become so popular.
Most MP3 players provide limited ability to navigate (move forward
and backwards) through the content. Some MP3 players do allow "time
jumps" or allow an individual to create “bookmarks” that create reference
points for easy navigation.
DAISY
DAISY content can be navigated via a logical heading
structure as well as traditional page numbers, offering an efficient and easy
method to navigate audio content. In addition to improved navigability, users
can also interact with the content in more powerful ways. Keyword searching and
the ability to add custom bookmarks to the content allow auditory learners to
interact with their learning materials in much the same way as visual learners
interact with traditional printed materials.

Suggested accommodations for visually-impaired students:
- Make allowances for special seating.
- Be open to communication with students.
- Post PowerPoint presentations online in advance.
- Provide advance copies of handouts in class or online.
- Use more descriptive speech and avoid words like,
"this, there, and that".
- Request an electronic version of your textbook when you
order it.
- If an electronic copy of your textbook is not available
from the publisher, ask for an additional desk copy.
- If you are notified of a student needing accessible

These requirements extend the obligations of Section 508 of the Rehabilitation
Act of 1973 as Amended in 1998 to all California State\ entities.
Legal Obligations
California
community colleges, along with all public institutions of higher education, are
required to provide access to classes and materials for students who have
disabilities. A number of federal and state laws apply, but we are going to
focus on two: Section 504 and Section 508 of the Rehabilitation Act.
Section
504 applies to any college campus that has received federal funding. If you
take the money, the requirements of Section 504 trail along with it.
Section
508 applies to the California community colleges and the California State
Universities because of California state law (SB 105 and SB 302, codified into
California State Law as part of the Education Code Section 11135).
Section
504 requires that the specific needs of individuals with disabilities be
accommodated so that those individuals can learn as effectively as their
nondisabled peers. These accommodations are driven by student requests. The
disability service offices on your campuses are set up specifically to deal
with accommodations under Section 504.
(Please
note that accommodation laws also apply to campus employees, and your campus
human resources department will handle these. The campus disability services
office is specifically for student needs.)
Section
508, on the other hand, requires that the campus buys (in the case of
hardware/software) or creates (in the case of Web pages and distance ed
courses) provide access to all electronic and information technology
(E&IT—Web pages, computers, course management systems, hardware, software,
etc.) for all individuals with disabilities—students, staff, and even the
general public. Complying with Section 508 is a general campus responsibility
and is not driven by individual request, rather the E&IT on campus is
expected to be as accessible as possible right from the start.
Section
504 deals with specific accommodations for specific persons; Section 508 deals
with general access for all persons.
Under
Section 504, the individual makes a request and the campus honors it. Under
Section 508, the idea is to have the access already in place whenever someone
who needs it shows up—even if you did not know the person was coming.
Section
508 is designed to provide general access. When something is not fully
accessible, however, then the individual makes a request under Section 504. So
the two laws work together, with Section 504 taking over whenever full access
has not been provided under Section 508.

What these Laws Mean to You
Section 504, Section 508, and Distance Education
Under
Section 508, distance education courses need to be designed in an accessible
way from the very beginning. Section 508 is very clear on the requirements for
Web accessibility, giving very specific standards, which include examples. An
extensive look at the Section 508 standards is beyond the scope of this course,
however, the point of all the standards is to ensure that materials delivered
on the Web are accessible to and usable by individuals with disabilities. The
key points to keep in mind are summarized below.
Usable Web Accessibility
- Use Headings
- Describe content-based images
- Name hyperlinks descriptively (examples below illustrate good usability practices for labeling links). To read more:
Hyperlinks
The
ability to create and present "links" to other documents and information
is a major component of Web pages. While this is one of the simplest methods to
direct individuals to other Web pages, documents, or to perform specific
functions, hyperlinks can also have potential accessibility challenges. The
issue is not how hyperlinks function, but rather the "name" that is
used to identify the specific hyperlink itself.
One feature of screen readers is the ability to collect all the hyperlinks on a Web page and present this information to the individual. This allows the user to listen to a list of hyperlinks that are available on the page and navigate directly to the desired hyperlink as opposed to searching line-by-line.

Links list in JAWS (screen reader)
When
hyperlinks have a descriptive name that identifies the purpose of the link, it
is fairly easy for an individual to navigate the Web page and choose the
appropriate hyperlink. However, hyperlinks may be named in such a way that
either the purpose or destination of the link is unclear. For example, often
times a news headline or teaser to a full news article will have the hyperlink
text "Read More" for the rest of the article. An individual using a
screen reader will be informed that there is a hyperlink called "Read
More." On the Web page, we can visually infer that the "Read
More" hyperlink will provide more information about the news headline that
it’s closest to. But for someone who is unable to see the page itself, the text
"Read More" does not provide the context as to the name of the news
headline. The problem is magnified when there are multiple "Read
More" hyperlinks on a page that takes the person to different Web pages. A
person using their voice to access the links on the webpage will be able to
navigate more efficiently if descriptive names are used for links.
Best Practices for Hyperlinks
Generally
speaking, it is beneficial to identify the purpose or function of the hyperlink
as part of the hyperlink name. This often raises questions as to "how much
is enough" and "how long is too long" regarding the name of the
link itself. While there are no established answers, the name should be
descriptive enough so that the user can understand or infer what information
will be obtained by choosing that specific link. Example: "Read More about
the Carl Brown Scholarship" rather than just "Read More."
For hyperlinks that take a user to different file types (e.g., QuickTime movie, PDF, Word document), it can be helpful to include the file type in the name of the hyperlink itself. This can be as simple as appending the file type to the end of the hyperlink name. For non-HTML based documents, you could also include the approximate file size. This is not specifically an accessibility issue, but allows the user to determine how large the file will be and whether or not the connection speed will support such a file size. Here are some examples of including the name and file information in a hyperlink: Adobe Acrobat Datasheet [PDF, 500K], Course Syllabus [PDF], Letter of Introduction [MS Word], View Memorial Service [Quicktime MOV]

Example of unclear directions: Click Here
- Include symbols with color to *emphasize differences*
- Navigate
the Web page using the keyboard
Solutions for MS Word
- Use the styles and formatting options to specify headings
- Avoid using tables or text boxes to control layout and positioning of Word documents
- Include text descriptions when adding content-rich images
- Specify
column headers for data tables
Solutions for MS PowerPoint
- Use the PowerPoint templates
- Add your text descriptions to images
- Avoid using the Save as Web page option as the only delivery method, can save as PDF using Microsoft Save as PDF plug-in OR Adobe Acrobat
- If recording PowerPoint as a video, need to develop a captioned version
Solutions for Adobe PDF Documents
- Start with the creation of accessible MS Word/PowerPoint documents
- Styles applied in MS Word can automatically create PDF Bookmarks
- Use the “Adobe PDF” option from the menu bar of MS Word
- Need to be using MS Word 2000 or later AND Adobe Acrobat 5, 6, 7, 8, or
- Another
option is the Microsoft Save as PDF plug-in in Office 2007
