Patent ID: 8917221

Claim:
A method of controlling data displayed by a dual-screen touch screen device, comprising: determining that the dual-screen device has moved from a closed landscape state to an open landscape state; determining a relative position, of a plurality of relative positions, of a first screen that originally displayed data from a first application when the dual-screen device was in the closed landscape state and a second screen that was not displaying data from the first application when the dual-screen device was in the closed landscape state, wherein, in the closed landscape state, the first screen and the second screen are back-to-back; and controlling data displayed on the second screen in the open landscape state based on the determined relative position of the first screen and second screen, wherein the determined relative position is where: the first screen is in a landscape state and in a same plane above the second screen and transitioning a window from the first screen to the second screen by emulating a dropping of the window across a transition area to the second screen under a force of gravity, or the second screen is in a landscape state and in the same plane above the first screen and transitioning a window from the second screen to the first screen by emulating a dropping of the window across a transition area to the first screen under the force of gravity.
