If a user usually has limited vision (blind people), rather the difficulty of using a smartphone, which must use physical tomobl or see an icon via the touch screen, now begin to be overcome. Google brings voice feature that is built on OS Ice Cream Sandwich. Such features will make a sound, such as reading the name of the icon or text when the user, especially the blind. This can create a user who has limited vision, not need to see the screen on a smartphone, so just removing her voice, alone and automated, the user will get the look he wanted.
Once users find the application you want to enjoy, this feature will provide the ease in which users simply press the icon, and then shifting up and down to find what they are looking for. It only takes two fingers, because one finger is used to scroll and identify the item.
To be sure this feature is not yet have a name, and Google may have to optimize it in order to function fully for users with limited vision. In addition there has not been an official release when this feature will be present for the supported smartphones with Android 4.0 or Ice Cream Sandwich.
