Further, the computer 7450 can also include a gyroscope, an acceleration sensor, a global positioning system (GPS) receiver, a fingerprint sensor, or a video camera. For example, a detection device including a sensor which detects inclination, such as a gyroscope or an acceleration sensor, is provided to determine the orientation of the computer 7450 (whether the computer is placed horizontally or vertically for a landscape mode or a portrait mode) so that the orientation of the display screen can be automatically changed.
Furthermore, the computer 7450 can be connected to a network. The computer 7450 not only can display information on the Internet but also can be used as a terminal which controls another electronic device connected to the network from a distant place.
Note that this embodiment can be combined with any of the other embodiments in this specification as appropriate.
