Abstract

A mobile device operates in a standard mode of operation, or operates in a visually impaired (VI) mode of operation designed for visually impaired users and in which a display screen of the mobile device is turned off by default. The display screen may thus remain turned off in the VI mode even when conditions under which the display screen is turned on in the standard mode are satisfied. The display screen may further remain turned off in the VI mode even when conditions under which a touch-screen input interface of the mobile device is turned on in either of the standard and VI modes. The mobile device may be configured to automatically transition from the VI mode to the standard mode in response to detecting a gaze directed towards the display screen.
