Computer-implemented method of activating blind navigation of control device such as smartphone with touch display interface, involves constituting a user interface on touch display interface, as icon

摘要

A user interface (501) is constituted on the touch display interface, as an icon, by selecting a fixed portion of the touch display interface. The touch display interface is reconfigured to receive a set of commands corresponding to a user interface (502), including one or more contact movements on the touch display interface. A touch input motion is received across the touch display interface, and an instruction referring to the transfer of command is determined from the set of commands, based on the received contact motion input. An independent claim is included for control device.
