Abstract

Provision of a user interface for computing devices equipped with a touchscreen display and a digital camera that magnifies a portion of a displayed image within a user's gaze. A user may calibrate their mobile device by touching a portion of the touchscreen with one or more fingers and following a moving image on the display with their eyes. The mobile device may track where a user is looking, and if the user is looking at the mobile device display, a portion of the display in the vicinity of the user's gaze may be enlarged. In an embodiment, if the user is looking at a virtual keyboard, key icons near the user's gaze may be increased in size commensurate with the user's finger tip size. In this manner, a user can accurately select individual keys in a virtual keyboard that fits within a mobile device display.

Description

technical field [0001] The present application relates generally to computing device user interfaces, and more particularly, to user interfaces suitable for mobile devices equipped with touch screens. Background technique [0002] Mobile computing devices equipped with touch screen displays have enabled a new generation of personal electronic devices. Touch screen displays provide both a graphical display and a flexible user interface, and thus enable the device to eliminate physical keys and buttons in favor of a larger display. Such mobile devices typically include a graphical user interface system that enables a user to enter commands by touching icons presented on the display. A common form of user interface presents a virtual keyboard or keypad with multiple small key icons arranged in the manner of a traditional physical keyboard or keypad. While the virtual keyboard user interface is intuitive and useful, the limited size of touch screen displays in typical mobile d...
