Abstract: A CE device for, e.g., displaying the time can incorporate an accelerometer to provide various features and enhancements. For example, tilting of the housing as sensed by the accelerometer may be used for controlling a volume output by an audio display, and/or for controlling a position of a screen cursor relative to underlying presentation on a visual display, and/or for controlling motion of a virtual object presented on the visual display; and/or for rotating a presentation on the visual display to always be oriented up and/or for determining that a person has tapped the housing based on signals from the accelerometer and in response thereto presenting an image of a rotatable object on the display.

Abstract: An electronic book with opposed displays facing each other on a foldable housing can present book text on each page in portrait mode. Upon receipt of a mode change signal caused by, for example, the user rotating the book 90°, the lower display can display an image of a keyboard and/or text in landscape mode while the upper display can present text in landscape mode. The keyboard image may be for a user-selected language.

Abstract: An electronic book can transfer book files to other cooperating electronic books using peer-to-peer principles and/or using wireless broadcast transfer principles. The electronic book can also automatically reformat a book file into a native format used by the book without user interaction. Additional electronic book features are also disclosed.
