To open up the Accessibility options, you need to go to the settings page by pressing the menu key on your device and selecting ‘settings’. In the settings menu, scroll down to look for ‘Accessibility’ and tap it.
The Accessibility page may have various options. You need to look for ‘TalkBack’ and tap it. ‘TalkBack’ is one of the common Accessibility features available on Android Smart-phones. It is immensely useful for the visually impaired since it reads out all commands, alerts, page titles and dialogue boxes.
Once on the TalkBack page, you have to switch it on by sliding the button on the top right corner. This will present you with a dialogue box warning that TalkBack can collect sensitive information such as numbers and data you may type. This is a generic warning and does not necessarily mean an application is malicious. Tap ‘OK’ to proceed.
After you tap ‘OK’ another dialogue box may appear, asking you if you wish to enable ‘Explore by Touch’. Using this feature, you can hear descriptions of what is on the screen as you touch it. This is a very useful feature and it is advised that you enable it.
If you enable Explore by Touch, you will be taken to a short tutorial. Follow the instructions and learn how to use it. Explore by Touch greatly facilitates use of the smart-phone by the visually impaired.
TalkBack itself has a settings option, which you can use to further tweak the service. You can customize vibration feedback settings and enable options like ‘speak caller ID’.
