Patent ID: 8493344

Claim:
A method, comprising: at an accessible electronic device with a touch-sensitive surface and a display: displaying a plurality of user interface elements on the display; detecting a first user interface navigation gesture by a finger on the touch-sensitive surface; in response to detecting the first user interface navigation gesture by the finger on the touch-sensitive surface, navigating in the plurality of user interface elements in accordance with a current navigable unit type, wherein the current navigable unit type is set to a first navigable unit type selected from a plurality of navigable unit types; detecting a first user interface navigation setting gesture on the touch-sensitive surface, wherein the first user interface navigation setting gesture is independent of contacting a location on the touch-sensitive surface that corresponds to any of the plurality of user interface elements; in response to detecting the first user interface navigation setting gesture on the touch-sensitive surface: changing the current navigable unit type from the first navigable unit type to a second navigable unit type selected from the plurality of navigable unit types; and outputting accessibility information about the second navigable unit type; after changing the current navigable unit type from the first navigable unit type to the second navigable unit type, detecting a second user interface navigation gesture by the finger on the touch-sensitive surface, wherein the second user interface navigation gesture is substantially the same as the first user interface navigation gesture; and, in response to detecting the second user interface navigation gesture by the finger on the touch-sensitive surface, navigating in the plurality of user interface elements in accordance with the current navigable unit type, wherein the current navigable unit type is set to the second navigable unit type.
