Embodiments provide a user interface for computing devices equipped with a touchscreen user interface/display and a digital camera that enhances 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 enhanced in size. 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.

In a particular embodiment, a method includes applying a first feature detector to a portion of an image to detect a first set of features. The first set of features is used to locate a region of interest, and a boundary corresponding to the region of interest is determined. The method also includes displaying the boundary at a display. In response to receiving user input to accept the displayed boundary, a second feature detector is applied to an area of the image encapsulated by the boundary.
