Help elsewhere: Guidelines for
accessible web design | What are assistive technologies?
Support for university web authors: main page
It is the aim of this page to be of assistance to disabled and dyslexic students and staff using computing facilities both on and off campus.
Adjustable monitor arms are installed on one PC workstation in all open
access laboratories, (and on two PCs in the case of Lab J). Monitor arms permit adjustment of the height of the
monitor as well as of the user's viewing and focal distance from the screen.
Positioning the monitor screen at the correct viewing height eliminates strain
to the neck and upper back of the user, as well accommodating users seated at
different heights, for example in a wheelchair.
Two 19 inch LCD monitors, (21
inch approximate CRT monitor equivalent), have been installed on the
machines with monitor arms, (see above), in labs C and M to assist users
with visual impairments. More large monitors are planned, but not yet
available.
All open access laboratory PCs, installed with the Windows 2000 operating system, or the Windows XP operating system, have the below accessibility menu enabled on the Windows Start Bar:
Magnifier is a display utility that makes the computer screen more readable for people who have low vision. It creates a separate window that displays a magnified portion of the screen enabling users to:
Adjust the magnification level of text and images in the magnification window.
Change the size and location of the magnification window.
Change the position of the magnification window on the desktop.
Invert the screen colours.
Use a high-contrast setting.
Magnifier also has a number of tracking options, which include:
Following the mouse pointer as it moves on the screen.
Following the keyboard focus, which centres on the location of the cursor.
Following text editing.
Narrator is a very basic text-to-speech utility (screen reader). It reads what is displayed on the screen, (the contents of the active window, menu options, or text that has been typed). Narrator is designed to work with Notepad, WordPad, Control Panel programs, and Internet Explorer. It also allows users to customize the way screen elements are read. Users can:
Hear new windows, menus, or shortcut menus read aloud when they are displayed.
Hear typed characters read aloud.
Watch the mouse pointer follow the active item on the screen.
Adjust the speed, volume, and pitch of the voice.
IMPORTANT: To make use of this facility in the open access laboratory users must bring their own headphones. There are also plans for headphones to be made available for purchase from the Help Desk in the near future.
On-screen Keyboard displays a virtual keyboard on the computer screen that enables use of a pointing device, joystick or mouse to input text or key strokes. It can also help people who do not know how to type.
There are three typing modes:
Clicking: Select the on-screen keys to type text.
Scanning: Type keyboard characters by pressing a hot key or by using a switch-input device as On-screen Keyboard scans and highlights areas of the keyboard.
Hovering: Point to a key by using a mouse or joystick for a pre-defined period of time, and the selected character is typed automatically.
The On-screen Keyboard allows users to:
View an enhanced keyboard that includes the numeric keypad, or view a standard keyboard without the numeric keypad.
Display the keyboard with the keys in the standard layout, or in a block layout in which the keys are arranged in rectangular blocks.
Display the U.S. standard keyboard, the universal keyboard, or a keyboard with additional Japanese language characters.
Select Click Sound to add an audible click when a key is selected.
Select Always on Top to keep the keyboard displayed on the screen when switching programs or windows.
Utility Manager brings all of the Windows 2000/Windows XP Accessibility programs together in one place. You can quickly check the status of an individual program, or start and stop any or all of them.
The Student Support Office has the following facilities available:
An embosser which can convert text to braille and "print" it in raised braille form.
A copy of the speech recognition software, Dragon Naturally Speaking. This allows users to dictate instead of typing, and to use a computer or surf the Web by voice command.
Students can arrange to use both of these facilities by contacting the Student Support Office, although access is limited.
JAWS 4.5 is an advanced screen reader for use with many software applications and the Internet. It uses an internal software speech synthesizer to read aloud information from the screen. JAWS is also capability of outputting to a refreshable Braille display (not yet available at the University).
Features include:
Multi-lingual software speech synthesizer (American English, British English, Castilian Spanish, Latin American Spanish, French, German, Italian, Brazilian Portuguese, and Finnish.)
An interactive talking installation which makes it easy to get started without sighted assistance.
JAWS supports all standard Windows applications (e.g. Outlook, Word, Excel, Internet Explorer).
JAWS is installed on one PC in every open access laboratory, (and on two PC's in Lab J). It is installed on all PC workstations where monitor arms have been fitted.
IMPORTANT: Users will need to bring their own headphones to make use of the audio features of this package.
TextHELP! Read & Write software aims to assist users with dyslexia or other difficulties which affect their English reading and writing abilities. It is a vocabulary support package which talks, types, checks spellings, and can even predict what the user wishes to type. TextHELP! Read & Write can be used with word processors, spreadsheets, databases, email and Internet. It provides a simple toolbar that "floats" on top of any open application waiting to provide assistance when called upon.
Features include:
Speech: It reads out loud as you type or reads any document. It also provides full screen reading of text, menus and icons.
Spell Checking: An advanced phonetic spell checker can automatically notify you when a mistake is made and can correct the most complex errors.
Homophones Support: homophones are colour-coded to help to proof and correct text. Descriptions of like sounding words are provided to ensure the correct word is selected.
Word Prediction: Phonetic and grammar based word prediction will offer suggestions as you type and will also learn your individual writing style.
Thesaurus: provides synonyms for words with descriptions and sample sentences to aid understanding.
Word Wizard: is a step-by-step process linking the word you know, to the word you are searching for.
TextHELP is installed on one PC in every open access laboratory, (and on two PC's in Lab J). It is installed on all PC workstations where monitor arms have been fitted.
IMPORTANT: Users will need to bring their own headphones to make use of the audio features of this package.
SmartDraw is a software program for creating business charts, technical drawings, and other diagrams. Its installation at the University is intended to assist users with mobility difficulties to create vector graphics with ease.
Features include:
A simple drag-and-drop drawing interface lets users draw any of the thousands of pre-defined shapes with a single click.
Built-in templates and examples
Built-in collections of clipart, images, and symbols
Automatic alignment and formatting
Many helpful accessibility utilities are available through the Windows Control
Panel, (although campus users must note that access to the control panel
accessibility options is not available in the labs, due to security reasons).
Home/staff PC users can view these options by opening Control Panel and double-clicking on
Accessibility Options
(icon
shown left). The following dialogue box will appear:
A brief outline of each utility is given below:
StickyKeys
A helpful application that allows
users to press a key and then release it, and then press the other key or keys
without having to press and hold all simultaneously.
FilterKeys
People who inadvertently brush against keys will benefit from FilterKeys,
which instructs Windows to disregard keystrokes that are not held down for a
minimum period of time. Most keyboards allow users to repeat keys by holding
them down. This can be a problem for people who have impaired dexterity.
FilterKeys lets you adjust or turn off the repeat feature.
SerialKeys
SerialKeys allows you to control the personal computer by using adaptive
equipment such as alternative keyboards or augmentative communication devices
that connect to the serial port.
MouseKeys
Permits control of the mouse pointer by using the keyboard instead of the mouse.
Actions include clicking, double-clicking, and dragging and dropping.
SoundSentry
This feature tells Windows to send a visual cue, such as a blinking title bar
or screen flash, whenever the system makes a sound. Turning on this feature
allows you to see messages you might not hear.
ShowSounds
Some applications present information audibly by using digitised speech or
other audible cues that might be unusable by a person who is deaf or hard of
hearing. ShowSounds allows user to instruct
applications to display closed captions for their sounds, (but only if the
application has closed-captions built in).
Customisable Sound Schemes
People who are hard of hearing or working in a noisy environment can adjust
the sounds and volume associated with various onscreen events, making the events
easier to distinguish.
High-contrast Mode and Schemes
Ready-to-use appearance schemes make it easier to see screen objects. You can
also set a global flag to advise applications to
present high-contrast text, and to avoid black text on a grey background or text
drawn over pictures.
Many helpful accessibility features are included as part of the Macintosh’s system software (System 7.x, 8.x, and 9.x), and others can be easily installed.
