Citation preview
Why I hate the Interweb!
And what we can do about it
It’s really disheartening to hear users say they hate the web
They tell me the only go online when they have to
But some disabled web users get such a bum deal
The web has the potential to give equal access to information for everyone!
When things go well
Why is the web still not accessible?
Accessibility viewed as too prohibitive and expensive
Some sectors have almost no take up – entertainment, lifestyle, Rock and Roll, fun!
Assistive technologies not fit for purpose?
Most popular browser not fit for purpose?
Disabled web users don’t know about the good stuff?
How much do we expect the user to know?
About our research
Conduct regular lab based tests with diverse users
Sites tend to be information based (rarely web apps or rich media)
Many of the issues fall outside of the WCAG 1.0 guidelines
Patterns often emerge across users with different needs who are surfing in different ways
This means solving these issues will have a broad positive impact on the overall user experience
For all users
Accessibility is usability
Issues uncovered by users in a typical recent test
Proportion of users facing each difficulty
The site being tested was information based with few transactions
Talking to our users
We surveyed our users to find out what they found difficult about the web
And what would be on their wish list for a dream web
Low number of respondents
Across a broad range of impairment categories
Screen reader users
Screen magnifier and Large text users
Deaf users
Users with dyslexia
Users with learning disabilities
Voice recognition software and keyboard users
Other issues
Be careful not to pigeon hole people – treat everyone as an individual
Amongst disabled users difference in the level of IT knowledge is vast from super geeks to technophobes
Those with the least technical knowledge may be most in need of assistance
Don’t make solutions based on technical know how
Solutions need to be easy to use
It’s not always easy to upgrade or install new software
How do we tell users about the good stuff?
How do we persuade users to try a tool again?
And some ideas from the team
Here’s what they said
Common issues
Page layout – no control, too crowded, no hierarchy
Typography – text size, colour contrast,
Flash (menus, adverts) – distracting, can’t operate
Remembering / inputting user name and password
CAPTCHA graphics
Having to scroll to view content
Filling in forms
New Facebook is difficult to use
Low take up in Web 2.0?
Johann Screen magnification software user
Partially sighted uses ZoomText and increases text size “I like pages were the developers have considered the colour
combinations they are using”
“Websites which are heavily dependent on animation or flash movies can also make viewing very frustrating.”
“I can use the directions part of Google maps with practice, but there is far too much scrolling around on maps for my liking, and the last time I tried to zoom in it didn't magnify anything.”
“I also find it difficult when things pop up on the right-hand side instead of taking up the whole screen. Although I am partially sighted, I am actually totally blind in my right eye, and this means I'm not as good at scanning as other people. ”
Partially sighted uses Zoomtext and increases text size Maps - Find these almost impossible to use, seem to run out of
control, would like to be able to make them full screen, almost running as a separate program, would like them also to be linked to info about public transport
Do not like the new style Facebook, it feels more messy and difficult to find things
Forms - Wish designers would make boxes slightly bigger and with clear lines round the outside of the boxes
My screen resolution means I often have to scroll across, this is my biggest bugbear about using the web.
Summary
Complex layout make navigation very difficult
Screen magnifier users are prone to RSI and posture related injuries
Different alignments make reading difficult
ZoomText is often slow and can be frustrating
Information on the right hand of the page can be easily missed
Tool which allows users to override page design
Reduce scrolling
Replace type settings and colour combinations
Convert fixed layout to relative
NicolaVoice recognition software / keyboard user
Nicola’s experience
What it’s like to use voice recognition or a keyboard
The problem with mouse clicks
Using webmail
Nicola’s wishlist
Mild motor difficulties
“Only a few things bug me. There is so much stuff that I would welcome a better filtering system on the search engines. I have never found a way to turn the page in a search engine that is offering many pages of results. “
“As my eyes and mouse skills deteriorate it is desperately boring to click on the Next button or a tiny number - there probably is short cut but I cannot find it. “
“Perhaps MS or Google could build a simple page turner on a single button to speed that process up.”
“One afterthought, there are many too many formats for video, audio etc. “
VR and keyboard user on Flash
“I get frustrated when developers make a Flash interface that has no simple HTML alternative, these often don't work when using VR. Anything with a click and hold requirement, like some calendars and menu designs, are useless if you can't use a mouse and rely on VR or other pointing software to work for you.”
VR = Voice recognition software
Summary
Many users can use the mouse but it causes pain and fatigue
Some users can’t use the mouse at all
Tabbing can be difficult and frustrating
Flash menus can be particularly difficult
Don’t rely on mouse over to identify links or icons
“It would really help if pages could be forced to fit the screen, to avoid scrolling and keep navigation simple and easy.”
Easy page turner for search engines
List of all the links on a page in one handy place
Users with dyslexia
Users with dyslexia
Difficulties with new Facebook interface
“The new Facebook is very hard to access all the features as instead of having all the applications… on one page, you have to select different pages. The set out of the page is now harder to find your way round,”
Some of the information websites content is hard to read as the font size is small and the background colour is white. From a dyslexics viewpoint, this makes the website not very useable. The websites would be more useable if they used a different background colour from white and bigger font. ”
“Filling in details for banks etc. I am not a brillant typing and make a lot of mistakes for example, pushing buttons by accident. This can sometimes be frustrating as when filling in your details if you accidently push a button, the page can change and delete in the details which you have filled in. “
Summary
Page design has a huge impact on this group of users
Colour combinations
Typeface
Colour combination
Layout
Flexibility
Cognitive overload and difficulties with short term memory can make navigation difficult
Users often have to rely on navigating – searching too difficult if there’s no spell checker
Screen reader users
Jaws users
“On Facebook for some reason the webpage seems to jump making it hard to click on the correct links. “
Facebook: incorrect labels
“As you may or may not be aware Facebook has a new design which seems even more difficult to use”
Form fields – no labels or incorrect labelling
CAPTCHA alternatives difficult to listen to
Most calendars don’t work without a mouse
Jaws users continued
“Combo boxes, magic numbers (CAPTCHA), form filling, watching TV, purchasing items.”
“I find webmail can be difficult to navigate.”
“I have tried to purchase tickets for flights: EasyJet, Virgin, British Airways, train tickets, football tickets but have found it either impossible or too time-consuming. However, you often get a big discount if you purchase on the internet. “
JAWs users - summary
Link text is really important – especially the first letter of the first word
Filling in forms, registration, logging in can be difficult
Audio feedback is really important
Many users have a very poor experience
Many users think Flash is inaccessible (full stop).
It can be hard to overcome the steep learning curve with constant set backs
Users with learning disabilities
The new Facebook is too difficult
Writing is too small
Keeps freezing
Difficult to log in and out
Memorising email address and password
Not big enough space to write in form fields
Fulham Football Club is also difficult please fix!
Information overload – confusing page design
Rich media and images can be very engaging
Summary
Put important information in important places
Keep it simple
Don’t overload users
Use rich media
Common issues
New Facebook interface
Frustrations with navigation
Excessive scrolling
Dependence on the mouse
Filling in forms
Remembering user names and passwords
Flash …
The current solution for accessible video is counter intuitive – please can we have an easy to use accessible player
When screen reader users hear “Macromedia Flash Movie” they automatically think inaccessible
YouTube is pants
What difference does it make?
Controlling video playback
For Kirin EasyYouTube was empowering
