Abstract: Disclosed is an electronic device that is detachably coupled to a frame of a head-mounted device that can be mounted on a head of a user. The electronic device can consecutively perform tracking of the user's head using a sensor, when sensor data is abnormally received. Thereafter, if the sensor data is normally received from the head mounted device, the electronic device can consecutively perform the head tracking, enabling the user's action and the visual information to coincide with each other, thereby reducing inconvenience or misoperation which may occur in the case of the conventional head-mounted device.

Abstract: Provided is a head-mounted display (HMD) apparatus and a method of controlling information output for the HMD apparatus. The HMD apparatus includes a frame in which one or more devices are installable, an interface unit to functionally connect to at least one of one or more devices installed in the frame and an external device, a detection unit to detect a user input, and a processor to perform a process of determining the one or more devices installed in the frame, controlling the interface unit according to the determination result, and controlling the one or more devices installed in the frame and the external device on the basis of user input detected through the detection unit.

Abstract: A connector of an electronic device and an electronic device having the same are provided. The connector of an electronic device may includes a mold fixed on a main board of the electronic device; a first connection pin having a first connecting portion protruded to one surface of the mold; and a second connecting portion separated from the mold and an extension that connects the second connecting portion and the mold.

Abstract: Provided are a method of controlling a camera of a device capable of minimizing a vision difference between a front camera and a user by displaying a reduced size preview image within a partial region of a display proximate to a lens of the front camera. When a photo is taken while the user views the reduced size preview image, a more natural image is captured.

Abstract: An electronic device providing information through a virtual environment is disclosed. The device includes: a display; and an information providing module functionally connected with the display, wherein the information providing module displays an object corresponding to an external electronic device for the electronic device through the display, obtains information to be output through the external electronic device, and provides contents corresponding to the information in relation to a region, on which the object is displayed.

Abstract: A method and an apparatus for detecting an accessory in an electronic device. A connection of accessory with an interface unit is detected. An analog signal in a predetermined frequency is generated. The generated analog signal is applied to an identification terminal of the interface unit. The applied analog signal is converted to a digital signal and the type of the accessory is identified based on the converted digital signal.

Abstract: An electronic device and icon arrangement method for the same that arrange icons on the basis of dominant colors thereof. The icon arrangement method for the electronic device may include: determining a dominant color of at least one icon; storing information on the dominant color of each of the at least one icon in associated with the at least one icon respectively; and displaying the at least one icon in an arrangement based on the dominant color.

Abstract: Disclosed herein is an apparatus for measuring residual stress, methods of measuring residual stress data and residual stress using the apparatus, and a recording medium for storing software of the residual stress measuring method. The present invention is advantageous for evaluation of a mechanical material property and is non-destructive. Further, the present invention is widely applied to fields ranging from a microscopic area, such as a thin film or micro device, to a large-sized structure, and is not influenced by a microstructure by controlling the range of an applied load. Further, the measuring apparatus of the present invention is minimized in its volume to be easily attached to an actual structure. Further, in the present invention, various attaching devices are employed, thus enabling the apparatus to be attached to various materials regardless of the size and type of object materials to measure residual stress.
