Automatic Adjustment Of Screen Size And Brightness

A system disclosed herein automatically adjusts the size or brightness of a screen area at which a user is looking based on the distance between the user and the screen, and/or whether the user is turned away from the screen. A device or controller detects

when the user moves closer to or away from the screen. In response, the controller

zooms in, brightens, or dims a specific area of the screen (not the entire screen) to enhance readability for the user.

When reading text on a mobile device, not all text or web pages are mobile-ready, and display very small text. Pinching and zooming is a work-around that does not always

work or becomes burdensome. If a user is looking at a display that is too small or dark and is difficult to read, then the user tends to bring the screen close to the face in order to see. If the display is too bright in a dark room, the user might hold the device farther away or turning slightly away from the device in order to see it. The system disclosed herein provides detection of these context clues to automatically adjust either the brightness or size of an area of the screen.

A mobile device includes a forward facing camera and related technology that detects

when the user is looking away from the device and then pauses the content in response. The system disclosed herein detects the distance between the user and the mobile device and automatically increases the size of the area at which the user is looking.

The disclosed system comprises sensors, cameras, and controllers to help determine the area of the display device that is of interest to the user. The fine print on some documents may be too small for a reader to read, for example. When the system detects that the user is straining to view the fine print, it automatically enlarges that section and scrolls the fine print as the user reads it, to provide a better reading experience.

To implement the automatic zoom in a preferred embodiment:

1. The user looks at content on a mobile device (e.g., web...
