Accessibility analysis - Soundscape

Screen reader issue :

On boarding

• Remove focus on “Accept Term of use” alone, as focus goes to checkbox and text before
• On boarding when the page change, the focus remains at the bottom instead of starting to top of screen again (waiting for feedback from google : https://issuetracker.google.com/issues/378168377)
• On boarding - selection of sound, use similar mechanism than for language selection to go through the sound list faster.

Main screen :

• Add heading to Sounscape title in top bar
• In the top bar, there is a checkbox, what is its purpose ?
• Edit box says “Hello Dave” but no such text is actually visible)
• Click on search button not closing the keyboar
• Attribution icon on map, cannot leave the modal (only with a back gesture, but a more straightforward way should be available
• Button at bottom announce “ My “ + pause + “Location”.

Markers and routes :

• Set heading to “Markers & routes
• Remove contentDescription for “marker icon” image
• Group all Getting started text
• Improve discoverability with talkback of the add button in route screen
• Routes tab contrast is too low when unselected
• “New route” title set as heading
• Associate “Name” label with edit box below, do the same for Description

Top left Menu :

• Set heading to “Settings”, “Manage Callouts”, “Manage Audio Engine”, “Debug settings”
• Remove “Callouts On”
• Beacon type + Voice type dialog : add number of item in the list
• When we select one beacon type, we have no confirmation, it just goes back.
• Speech rate : announce speech rate instead of percentage if possible, and remove focus on text

Large font/size issues :
On boarding

• Center “Get Starting” button text
• Add padding at bottom of screen “Listening to soundscape” + “Hear your surroundings”, “Finish”
