A geometric algorithm is used to reconstruct the two-dimensional content element appropriately on the viewing surface. The observer can observe the three-dimensional illusion of the two-dimensional content element out of the plane viewing surface in the observer's perspective at the viewpoint, as if the original two-dimensional content element were placed in the three-dimensional space. This allows easier viewing of material at off angles.08-22-2013
20150378502METHOD AND APPARATUS FOR MANAGING USER INTERFACE ELEMENTS ON A TOUCH-SCREEN DEVICE - A method and apparatus for managing a touch-screen device is provided herein. During operation UI elements are arranged and re-arrange dynamically and based on user's current contact locations on the touch screen. Preferably, the contact positions correspond to a user's finger positions so that the UI elements are automatically placed where a person's fingers make contact with the touch screen. Because the UI elements on the touch screen always “look for” the user's fingers, instead of the user looking for them, it becomes much easier and more time-efficient for a user to find a particular UI element.12-31-2015
