Abstract: A method and system for enabling a visually impaired user to use a touch-sensitive device. The present invention provides an interface for the visually impaired (IVI) system which enables a visually impaired user to use a touch-sensitive screen. The IVI system provides an explore mode in which a visually impaired user may determine which objects are on the touch-sensitive screen by dragging a finger over the touch-sensitive screen. In particular, the IVI system announces objects as a user touches them. For example, the IVI system announces text as it is touched and announces controls, such as buttons, as they are touched. In addition, the IVI system enables a user to execute controls. A user may execute a control, such as a button, by dragging a finger onto the control, and then, without dragging the finger off of the control, lifting the finger off of the touch-sensitive screen. The IVI system further enables a user to scroll through lists on a touch-sensitive screen.
