Each screen of BARD Mobile has a heading. It is on the navigation bar located at the top of the screen, directly below the device status bar, which displays the time and information about your device, such as the battery life. The heading tells you which screen or content you are managing.
Depending on where you are in the application, you can select the heading, which is located on the upper-left corner, to move back to the previous screen. TalkBack will announce your current location, followed by “navigate up” to signify the ability to move back to the previous screen. However, TalkBack will announce, “navigate home” when you have reached the heading of one of three main screens from which you cannot navigate back further. You can access these screens through the tab bar.
