I was waiting for BlackBerry to bring some more accessibility options for the visually impaired on BlackBerry 10. They are doing just that shortly with the upcoming August BlackBerry 10.2 SDK Gold release. That release will allow Cascade controls that will announce the UI to the user who has trouble reading. Here is how BlackBerry describes it:
Cascades applications and Cascades UI controls will be integrated with screen reader functionality, so that visually impaired persons can hear a speech presentation of the UI.
Its nice to see that BlackBerry is once again pushing forward with services for the visually and hearing imparied. I know one visually impaired BlackBerry 9900 user that is dying to upgrade to the Q10 with its physical keyboard.
