First Claim
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 from 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.

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.
