US Patent 8375305 Placement of user interface elements based on a window entry or exit point

Disclosed are various embodiments for placing user interface elements in a network page. A first network page is generated with client side code embedded therein that can track navigation input data associated with the user. The navigation input data can be interpreted to determine whether the user has a tendency to idle an input device in a particular area of the network page or exhibit any other behavior that allows a high value area to be identified.
