Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing contextual information for a notification. Logical relationships between panels for a user interface of the one or more computing devices are identified. A set of interface patterns that correspond to different logical relationships between panels and describe different spatial relationships for arranging panels having the corresponding logical relationships are obtained. At least one of the logical relationships between the panels for the user interface is determined to match a logical relationship corresponding to a particular interface pattern. The particular interface pattern is selected from among the set of interface patterns to specify the arrangement of the panels of the user interface. The user interface having the panels arranged in the user interface according to the particular interface pattern that is selected is provided.

Abstract: An electronic device including a lower body, an upper body, a first screen, a second screen and a detecting element is provided. The upper body is pivotally connected to the lower body and capable to rotate relatively. When the upper body rotates to make the detector detect that the upper body is at a closed position, the electronic device is switched to a first mode, the second screen disposed on an external surface of the upper body displays a first image. When the upper body rotates to make the detecting element detect that the upper body is at an opening position, the electronic device is switched to a second mode, and the first screen disposed on an inner surface of the upper body displays the first frame.
