Abstract: A case for an electronic device including a coupling member detachably coupled to at least a part of the electronic device. A cover, which has one or more folded positions ranging between an opened state and a closed state, the cover extends from the coupling member in a to cover a display of the electronic device, and at least one Force Sensing Resistor (FSR) sensor disposed in the cover to generate an interrupt based on a pressure applied thereto. The at least one FSR sensor includes one or more inner FSR sensors disposed on an inner surface of the cover, and one or more outer FSR sensors disposed on an outer surface of the cover.

Abstract: A wireless audio output device, a wireless audio output system including the same and a control method thereof are disclosed. When a user approaches the output device, while listening to music on a portable device, the output device automatically connects the wireless audio output system to the portable device, to reproduce the music of the portable device. The control method includes detecting the user, detecting the portable device if the user is sensed, and outputting an audio file being reproduced by the portable device using the wireless audio output system, if the portable device is detected.

Abstract: A multipurpose learning device having a picture book including a plurality of pages, wherein the pages turned in a top-to-bottom hinged direction instead of a side-to-side hinged direction, a memory unit having audio and video data stored therein, the memory unit being detachably connected to a touch board. A surface of the touch board is declined to a predetermined angle for enabling a user to easily position an electronic pen perpendicular to the touch board. Each sheet of the picture book includes a blank page and a picture page and picture information corresponding to a picture on one of the pages is displayed on a host device, such as a television. A user moves the electronic pen over a blank page which is positioned over the touch board, and a cursor is displayed on the host device at a position corresponding to the position of the electronic pen over the blank page and touch board.
