PRANEETH REDDY CHADA: There are billions
of people who use Android devices,
and it is important to remember that not everyone interacts
the same way.
In Android, there are various accessibility features
that help users to interact with the device
easily and customize according to their preferences.
In this episode, we will discuss how
the users with different disabilities
navigate and interact with the custom actions
in an app using the accessibility features
of Android.
Custom actions are reached by mainstream audiences
by long pressing on a UI element such as an image
or icon in order to reach more actions which are not always
visible on screen.
Non-sighted users can use the TalkBack screen reader
from built in accessibility features
to navigate and interact with the applications easily.
With TalkBack enabled, users can either use gestures to navigate
or by touch to explore.
In Google Play, users can add the apps to their wish list
by long pressing on a desired app
and selecting add to wish list.
Let's see how the TalkBack users can add apps to the wish list.
Once the TalkBack focus is on the desired app,
for example, Play Books, TalkBack
announces double tap to activate and double tap and hold
to long press.
After performing double tap and hold,
the custom menu opens, and the users
can swipe to add to wish list and double
tap on it to add the app to their wish list.
Users with limited upper body mobility
can navigate to the apps and custom actions
of apps using switch access.
For switch access, users can assign volume buttons
as switches.
Other options also include assigning the camera switches
and Bluetooth switches.
Let's see how switch access users can access the custom
actions for apps.
Once the volume keys are assigned,
press volume down key to move to the desired app.
Once the switch access focuses on the desired app,
let's say Play Books again, press volume up
key to bring the switch access action menu.
With volume down key, move to touch and hold action and press
volume up key to activate it, and the custom menu appears.
Now navigate to the menu with the volume down key
and select remove from wish list by selecting it
with the volume up key.
Users with limited vision would want
to increase the size of the display and the text
which will make it easier for them to read and interact
with the applications.
With Android display accessibility features,
the users can increase the display size and the text
to suit their needs.
With magnification and display zoom features,
low vision users can magnify the screen
and adjust the display as per their preferences.
Once the magnification feature is turned on,
users can drag the magnification window with two fingers,
and the screen will appear in a magnified view.
Users can then select the desired app and all the custom
actions associated with it by long pressing on an app.
Android accessibility also has a voice input
hands-free feature called Voice Access that lets us control
the device with our voice.
Users can use voice commands to open apps, tab buttons, scroll,
type, and much more.
Now let's look at how custom actions
can be done with Voice Access.
Users can say the command tap and hold on a desired app
to reveal any custom actions that
are associated with the app.
For example, with Voice Access, we
can say tap and hold Google Play games
to bring up the custom menu.
And by saying add to wish list, the app
can be added to the wish list.
We have explored some of the ways
users with different disabilities
navigate and interact with custom actions in an app.
Next up in this series, we will be
looking at the Android pre-launch report
and how developers can identify and fix accessibility issues.
Thanks for watching.
