Would you like your iPhone or iPad to expand or shrink on-screen images depending on how close it is to you? That could eventually be possible. A new Apple patent (number 20120287163) is for mechanism for automatically scaling the size of a set of visual content based upon how close a user's face is to a display.
In one implementation, the mechanism initially causes a set of visual content on a display to be sized according to a first scaling factor when the user's face is at a first distance from the display. The mechanism then determines that the user's face has moved relative to the display such that the user's face is no longer at the first distance from the display. In response, the mechanism causes the set of visual content on the display to be sized according to a second and different scaling factor. By doing so, the mechanism effectively causes the display size of the visual content to automatically change as the distance between the user's face and the display...| Read more »
