UA Digital Accessibility Program
Promotion, awareness and training initiative
In terms of digital accessibility and accessibility technologies
What are our goals
- Break digital barriers
- Create guidelines for the development of accessible digital content
- Advise and train the university community in the use of accessible technologies.
- Detect entrepreneurship opportunities through accessibility research,
- And the creation of communication channels for its dissemination.
Assistive Technology for visual difficulties
- Knowing the assistive technology for Windows 10
- Use of screen readers (NVDA)
- Braille display
- Use of screen magnifier
Knowing the assistive technology for Windows 10
- Windows 10 has main accessible elements (characteristics) for different profiles of people with disabilities.
- For see them, please click on start bottom (windows logo key) and then, click on setting item. Finally, click on ease of access.
Windows settings -> Ease of Access
- Now, in the left panel, we can see all he characteristics.
- The first option is Display, we can configure the text size of all Windows elements and software.
- Also we can configure the visual effects like as show / hide animations and transparecys.
1.2. Cursosr and pointer size
- In the next tap, we can configure the cursor and pointer size. We can change he size of the pointer doing click on one of the three options (small medium, big). And we can change the pointer colour: white, black and black/white (in this if the background is in black colour the pointer is in white colour and vice versa).
Cursor and pointer size
1.4. Colour filters
Filtros de colores como sólo mostrar escala de grises. Útil para personas daltónicas.
1.5. High contrast
- Next tap is High Contrast, we can click and turn on, then the high contrast is selected. The higher contrast is the background in black colour and the text in white colour.
- The next tab is hearing. This option is for people that only can hear by one ear.
- Also we can turn on and configure show audio alerts visually.
Audio mono and visual alerts
- In the speech tab we can turn on speech recognition.
- In this moment, we press Windows logo key + h and we can speech and the computer write the text. It is, the test is transcript automatically.
- If we press Windows logo key + S we can dictate text and control the computer using only our voice. For example: Open Word, File, Edit, etc.
- In the keyboard tab we can configure the use of the on-screen keyboard, and the keyboard appears in the screen.
- We also configure slow press keys for people with motor dificulties.
Use of screen readers (NVDA)
- NVDA is a open source and free screen reader software for Windows.
- We are going to download, run and use NVDA 2019
- Please, enter www.google.com in an web browser and type NVDA download
- Press en the first result. Official website download
- Braille display have a braille keyboard. This has two possibilities: the use of 6 keys, it is the Universal Braille, of the use of 8 keys, Computerized Braille.
- The Computerized braille is specially designed for scientific subject, for example mathematic subject. Because it allows more combinations of symbols. For example, in the Universal braille the number must be “a” and extra symbol. With Computerizes braille we need less space. However, Computerized braille is only for digital, it not can use for print.
- Can connect with computers and smpartphones. In the braille line, we can touch the text that appears in the computer/smartphone screen.
Use of screen magnifier
- Click on the windows logo key/settings/ease of access/vision section/magnifier and turn on. Or pressing windows logo key + "+" key.
- We can increase magnification with windows logo key + (plus) key or decrease the magnification with Windows logo key + (minus) key.
- We can close the magnifier with Windows logo key + ESC key.
Use of screen magnifier
- We can configure the Screen Magnifier when windows start or before.
- Mouse cursor and keyboard focus are options very important. It is very important click in “text insertion point” because, for example if we open “notepad” when we are typing, the screen is moving at the same time that the text appears.

How to create digital accessible documents for everyone?
What is accessibility?
Accessibility is the degree to which everyone can perceive, understand and navigate the information contained in a digital document regardless of their technical, cognitive or physical capabilities .
And how does a person with a disability access the content?
- If I can not see, I use a screen reader.
- If my vision is limited, I use a screen magnifier.
- If I can not listen to a movie, I read the subtitles.
- If I do not have mobility in my hands I can dictate and give orders.
- If I have trouble understanding what I read, I can configure the text to my needs.
Who uses accessible technologies?
The answer may surprise ...!
It's not just people without vision or hearing, it also includes:
- People with dyslexia (10% of the population)
- People with temporary visual problems or those related to age (9M higher in Spain)
- People who read subtitles of a video so as not to disturb their co-workers
- People who surf through the keyboard because they find it more efficient
- And more
- Paradigm shift.
- It is not about adapting content for groups of people with disabilities or others.
- It is about designing contents taking into account from the beginning that they can be perceived, understood and navigable by as many people as possible.
- Digital barriers are difficult to perceive
How to create accessible content? 👨🏻💻
- Create simple texts with simple language
- Use font sizes of at least 12 points
Use Sans Serif type fonts such as Arial or Verdana
- Use a sufficient line spacing; at least 1.5 lines
- Space between paraghraphs of 6 points
- Do not abuse the text centered or in CAPITAL LETTERS
Do not justify the text on both sides . It hinders their reading and, therefore, their understanding 👿, especially to people with dyslexia or low vision.
- Specifies the main language of the document and the language changes present in the text
- Otherwise, the pronunciation will not be correct and we will lose information.
Set default language:
File -> Options -> Language
Set language of a piece of text:
Select text -> language bar
Titles and structure
- Structure content in sections , improves understanding and facilitates navigation .
- Do not simulate titles by changing the appearance of the text, use styles .
View -> Navigation panel. It has double function:
- We get an idea of what the document is about
- We navigate through it easily
Images and non-text elements
- Includes a textual description in images and non- text elements.
- The description should not be superficial and should answer these questions:
- What is it?
- What's its purpose?
- What does it transmit?
What elements should we describe?
- Mathematical formulas
This is not just for blind people:
- Other vision problems
- Cognitive problems
Enter the alternative text
Demonstration of descriptions
Forms and SmartArt
- They are not textual elements, although they look like it and we enter text, at the end they are images without alternative text .
Describing a scheme
Well structured tables
- Simple tables without many groupings
- Use them only to show content, not to layout content
- Uniform tables: neither combine nor divide cells
- Do not leave empty cells: put empty text
Inserting title to tables (and illustrations) facilitates the understanding and purpose of the data.
Mark header rows
Repeat header on each page
Yeah now is accessible!
Use of color
Do not transmit information only with color
- The text of a link must clearly convey its purpose, even outside the context of the surrounding text.
- Prohibited: Click here 🙁, On this link 🙄, etc.
- There are users browse through lists of links 🤓
All information is valuable
- Indicate the format and size in the link
- We can use on-screen info tool for + info
How to check the accessibility of a document? 👨🏻💻
Check accessibility in Word or PowerPoint
How do I create a PDF in an accessible way? 👨🏻💻
- If we have taken into account aspects of universal design, when we save our Word document or PowerPoint to PDF, it will preserve accessibility options and be accessible. Otherwise, no.
- We should not save as PDF with the typical 'PDF Printer' type programs since they cause the resulting PDF to lose accessibility features.
Options save PDF
- Mark Create bookmarks using ➡️ Titles.
- Mark Tags of the structure of the document for accessibility.
- Document properties
- Uncheck Bitmap text when fonts are not embedded.
