Abstract: An application program switching method for an electronic device having a first body and a second body is provided. A relative position of the first body and the second body is changed from a first state to a second state to activate a second application program while an external message is received during a first application program being executed, and an image displayed by the electronic device is switched from an executing frame of the first application program to an executing frame of the second application program for replying the external message via a keyboard of the second body. Next, the relative position of the first body and the second body is changed from the second state to the first state, and the image displayed by the electronic device is switched from the executing frame of the second application program to the executing frame of the first application program.

Abstract: An electronic device includes a faceplate having a faceplate surface and a display at or near the faceplate surface for providing content to a user. The electronic devices can also include an input device proximate to the display for accepting input from the user. The electronic devices can further include a sensible orientation structure carried by the faceplate and at a fixed relative position relative to the input device. The sensible orientation structure is configured to provide the user with positional feedback relative to the input device via touching.

Abstract: A stylus for a portable apparatus is disclosed. The stylus is usable as a prop to support the portable apparatus to stand on a platform and comprises a main portion and a rotating portion. The main portion comprises a tip end and a pivot end, and at least one protruding rib is disposed on the pivot end. A positioning plate is disposed on one end of the rotating portion, and connects with the protruding rib. A bolt passes through the protruding rib and the positioning plate, so that the rotating portion could pivotably connect with the main portion. Furthermore, at least one positioning structure is formed on one end of the positioning plate. The cross-sectional shape of the positioning structure is an arc shape. The stylus further comprises an elastic component and a positioning ball. The elastic component presses the positioning ball in the positioning structure, so that the portable apparatus could stand on a table surface. In addition, at least one groove is disposed on the sidewalls of the stylus.
