1. A method of controlling visual content that is displayed on a display of an electronic device, comprising:
- analyzing a video signal to detect facial features of a user of the electronic device and to establish a parameter indicative of a distance of the user form the display based on the detected facial features; and
adjusting the displayed content based on the parameter to facilitate user viewing of the displayed content at the indicated distance by varying a layout of a plurality of windows displayed on the display so that the plurality of windows are displayed in one of a side-by-side arrangement when the user is less than a predetermined distance from the display or an overlapping arrangement when the user is greater than the predetermined distance from the display; and
wherein the analyzing further includes determining a viewing angle of the user with respect to the display and the adjusting further includes skewing the displayed content so as to be non-uniformly varying in size across the display based on the viewing angle.

Abstract
A technique for managing the display of content on a display of an electronic device may be based on a distance of the user to the display. The distance may be estimated by analyzing video data to detect a face of the user and establish a distance parameter based on a relationship between facial features. Based on this information, the displayed content may be adjusted to facilitate easy viewing of the displayed content, such as by changing the size of the displayed content, the layout of the displayed content, or the number of visual elements that make up the displayed content.

8. An electronic device, comprising:
-
an imaging device that generates a video signal containing a representation of a user of the electronic device; a display that displays visual content to the user; and a controller configured to analyze the video signal to detect facial features of the user of the electronic device and establish a parameter indicative of a distance of the user from the display based on the detected facial features, and wherein the controller adjusts the displayed content based on the parameter to facilitate user viewing of the displayed content at the indicated distance by varying a layout of a plurality of windows displayed on the display so that the plurality of windows are displayed in one of a side-by-side arrangement when the user is less than a predetermined distance from the display or an overlapping arrangement when the user is greater than the predetermined distance from the display. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
