  • Patent number: 10019151
    Abstract: 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.
