Accessibility is often connected to the needs and demands of people with impairement. This presentation - by means of practical examples - shows that vast majority of users can benefit from accessibility.

1. How to improve UX by
implementing accessibility
Radek PAVLÍČEK, Blind Friendly Web

2. Hi. My name is Radek and I am
member of Blind Friendly Web team.

3. I am also an author of blog Poslepu.cz and I
work as accessibility consultant.

4. In this presentation I would like to go on with
topic, which I presented at WebExpo
conference 2012.

5. What is accessibility
good for?

6. Availability – user
must be able to get
on the web.

7. Controlability – user
must be able to
operate the web.

8. Understandability –
user must understand
the web.

9. Orientation – user must
be able to find the way
through the web.

10. Time – user must
be able to fullfil his
or her task in
reasonable time.

11. Accessibility is often perceived as a matter
of handicapped people only.

12. One accessibility to rule them all?
Can we fully fullfil needs of all of the

13. Demands and needs of particular groups of
people with impairement vary.

14. Removing barrier for one
group could create barrier
for another.

15. Real life example. Orientation around this
swimming pool was no problem for my
blind colleague.

16. Although this swimming pools looks very similar to the previous one, it
was designed primarily for the needs of wheelchair users and there
were no natural guidelines for the blind. That is why the orientation for
them was very complicated.

17. This lowering is very suitable for wheelchair users, but is not
good for the blind, because they don´t know where is the
border between the sidewalk and the road.

18. Special kind of cobbles makes this
lowering accessible also for the blind.

19. Some adaptations are useful
only for users with special
needs

20. Sign language

21. Audio description of movies

22. Hidden headings

23. But the rest is useful for vast
majority of users

24. Audio information
Barrier-less
From accessibility adjustement of this tram profit also those,
who travel with pram, or passengers, who use audio
information about particular stops to be informed where they
are and where they must get off.

25. Real life examples

26. Subtitles are useful not only for people with hearing
impairement, but also for those, who do not
understand spoken language very well.

27. Missing text
alternative
There is no button which I can
click on.

28. Explicit association of controls
with their labels
When you create explicit association, the
clickable area is larger, because you can
click also on the label.

29. Keyboard shortcuts – you can operate
the web in very effective way.

30. Proof, that accessibility is beneficial to all users,
can be found in this report.

31. Scope of the investigation
39 000 pages
in total
Automated 1 000 home pages User
testing testing
50 users with
variety of
impairements

32. Completed tasks
Although control group, that consists of non-disabled web users, was able to complete all the
tasks, blind users on low accessibility websites completed only 67 %.

33. Duration
On low accessibility sites both groups were slower and they need more time to complete their
tasks. In other words, on high accessibility sites they were able to complete their tasks faster
and easier.

34. Remember
Accessible web is
beneficial to all users,
not only to users with
impairement.
