## Abstract

A multi-screen user device and methods for controlling data displayed thereby are disclosed. Specifically, the control of data displayed by at least one of the multiple screens of the multi-screen user device is conditioned upon the relative orientation of the multiple screens, whether the device orientation is changed from a first state to a second state, and user input received.

## Claims

### Claim 1

A method of modifying a window stack in response to an orientation change of a multi-screen device, the method comprising:
determining that the multi-screen device has rotated from a first orientation to a second orientation;
determining a relative size and orientation of at least one window in a window stack stored on the multi-screen device based on the rotation of the multi-screen device; and
controlling the display of the at least one window stored in the window stack based on the determined relative size and orientation of the at least one window in the window stack.

### Claim 2 (depends on 1)

The method of claim 1, wherein a first screen is determined to be above a second screen.

### Claim 3 (depends on 1)

The method of claim 1, wherein a first screen is determined to be below a second screen.

### Claim 4 (depends on 1)

The method of claim 1, wherein the rotation of the multi-screen device is determined, at least in part, based on data received from an accelerometer.

### Claim 5 (depends on 1)

### Claim 14 (depends on 8)

The computer-readable medium of claim 8, wherein a first screen is determined to be above a second screen.

### Claim 15 (depends on 8)

The computer-readable medium of claim 8, wherein a first screen is determined to be below a second screen.

### Claim 16 (depends on 8)
