6. Inclusive Design and Mobile Devices Flashcards
What are the advantages of mobile devices for disabled people? (3)
AT - Mobile devices come with accessibility features
Sensors
Apps
What are some potential issues with mobile devices? (4)
Screen size - small text, and images that cannot be resized affect people with low or limited vision
Touchscreens - problematic for people with dexterity problems (too small ‘touch’ areas that require precision).
Affordability - Latest mobile tech is expesnive which can be an issue for many people with disabilities.
Privacy - An issue for people who use voice to navigate their devices/ or screen readers to read out messages to them in public spaces
What are the advantages and disadvantages of not having separate mobile accessibility WCAG guidelines?
Developers and designers only need to become familiar with a single set of guidelines. However:
Some extra guidance is still required to account for mobile-specific interaction patterns (e.g touch interaction)
Devs and designers have to translate web guidelines to native apps
How can we meet WCAG’s principle Perceivable on mobile?
Adaptable - Support changing text size and don’t suppress zoom
Distringuishable :
Reduce content on screen, by providing a dedicated mobile version
Adapt link length to viewport
Make content and controls a reasonable size
Increase contrast (mobile devices are often use in glare-prone conditions, which heightens the importance of good contrast).
How can we meet WCAG’s principle Operable on mobile? (6)
Padding - Reasonable target size and spacing. Include padding
Gestures - Gestures should be easy to carry out (e.g. tap, swipe) and discoverable
One hand - Controls should generally be operable with one hand
Provide alternatives to device manipulation gestures (e,g. shaking, tilting)
Input modalities - Support external keyboard
How can we meet WCAG’s principle Understandable on mobile? (4)
Readable - Put important items upfront and above the fold if possible
Predictable:
Be consistent with layout
Clearly indicate actionable items by following conventions (e.g. button shape and contrast, iconography, colour and underline for links).
Input assistance - Provide help / instructions for custom gestures (e.g. overlays, tooltips, tutorials).
How can we meet WCAG’s principle Robust on mobile?
Keyboard - Support the right onscreen keyboard for data type (e.g. type = email, type = tel).
Minimise text entry
What in built accessibility features do mobiles have for people with visual impairments? (4)
Screen reader - e.g. VoiceOver (Apple) / TalkBack (Android)
Screen magnifier
Colour/ contrast options - e.g. dark mode
Text size
What in built accessibility features do mobiles have for people with hearing impairments? (4)
Captions
Haptic feedback
Real Time Text / TTY (teletypewritter) mode: use text to communicate on phone calls.
Hearing aid support
What in built accessibility features do mobiles have for people with motor impairments? (3)
Voice input / navigation
Assistive touch (Apple) – Use onscreen menus and controls to access gesture-activated features, instead of pressing hardware buttons or performing device manipulation gestures
Switch support - allows users to interact with their device using a switch instead of the touchscreen
What are some examples of mobile experiences for people with disabilities? (5)
Navigation and maps (find accessible spaces, get audio navigation instructions)
Communication aids (e.g. word prediction for people with aphasia)
Peer support
Taptapsee - uses device camera and voiceover to identify subjects out loud
Bemyeyes - Connects visually impaired people with sighted volunteers through live video
