Abstract: There is provided a device that includes: a display; at least one sensor disposed to be adjacent to the display; a biometric sensor disposed in at least a partial region of the display; and at least one processor, wherein the at least one processor can be set up to receive an input in the at least a partial region from an external object, by using the at least one sensor or the biometric sensor, and to obtain biometrics of the external object by using the biometric sensor on the basis, at least partially, of the input by the external object.

Abstract: Disclosed is an electronic device including a transparent member, a display that is disposed under the transparent member and that includes a plurality of pixels, an image sensor disposed under at least a partial area of the display, and an optical path layer disposed between the at least a partial area and the image sensor. The optical path layer includes an incident path of light that is formed such that, when light output through the plurality of pixels is reflected from the transparent member and an external object in contact with the transparent member, light reflected from the external object is delivered to the image sensor and light reflected from the transparent member is interrupted. Besides, it may be permissible to prepare various other embodiments speculated through the specification.

Abstract: An electronic device according to various embodiments comprises: a display; at least one sensor disposed to be adjacent to the display; a biometric sensor disposed in at least a partial region of the display; and at least one processor, wherein the at least one processor can be set up to receive an input in the at least a partial region from an external object, by using the at least one sensor or the biometric sensor, and to obtain biometrics of the external object by using the biometric sensor on the basis, at least partially, of the input by the external object. Other embodiments are possible.

Abstract: A portable audio output apparatus, including an audio output module configured to be in contact with a user's body and to output an audio signal, and a body fat sensor configured to sense a body resistance value of the user through at least four body contact nodes, is provided. At least two of the nodes are placed at outer surface areas of the audio output apparatus that are out of contact with the body if the user wears the audio output apparatus.

Abstract: A method and apparatus is provided for controlling the multitasking operations of a mobile terminal having at least one touchscreen based on the input signals corresponding to touch events detected on the touchscreen. A method for controlling multitasking operations of a mobile terminal having at least one touchscreen according to the present invention executes an application in response to a user request while at least one other applications is running, displays an execution window of an application selected from the currently running applications in an auxiliary screen in response to a touch event detected on the touchscreen, and displays the execution screens of the applications running concurrently, except for the application whose execution window is displayed in the auxiliary screen, in a main screen, accumulatively.

Abstract: A Bluetooth®-based communication system and method are disclosed. A communication method for a short range wireless communication system includes generating, at a first terminal, a list of second terminals supporting a chat function; establishing at least one asynchronous connectionless link between the first terminal and at least one second terminal; and exchanging chat packets through the asynchronous connectionless link between the first and second terminals. The communication system and method for portable terminals according to the present invention enable the portable terminals to exchange messages in the unlicensed 2.4 GHz Industrial Scientific Medical (ISM) frequency band without engagement of a fixed base station, whereby it is possible for the portable terminals to communicate outside a main communication system coverage.
