Abstract: Disclosed herein is an apparatus and method for detecting an emotional change through facial expression analysis. The apparatus for detecting an emotional change through facial expression analysis includes a memory having at least one program recorded thereon, and a processor configured to execute the program, wherein the program includes a camera image acquisition unit configured to acquire a moving image including at least one person, a preprocessing unit configured to extract a face image of a user from the moving image and preprocess the extracted face image, a facial expression analysis unit configured to extract a facial expression vector from the face image of the user and cumulatively store the facial expression vector, and an emotional change analysis unit configured to detect a temporal location of a sudden emotional change by analyzing an emotion signal extracted based on cumulatively stored facial expression vector values.

Abstract: A battery case from which a battery is easily separated and a remote controller including the same are provided. The battery case includes a body including a battery container and a pressing member installed in the battery container and configured to press the batteries in response to the batteries are being from the body.

Abstract: Disclosed is a method for bi-directional calling between an open system module and a mainframe system module, which is performed in a computing device including one or more processors and a main memory storing commands executable in the processors. The method may include: receiving, by a front-end interface, a calling for a mainframe function on the mainframe system module from the open system module program; requesting, by an entrance point processing unit of the front-end interface, information on the mainframe function to a program processing unit of a back-end interface; controlling, by the entrance point processing unit of the front-end interface, a register processing unit of the back-end interface to set a mainframe register value used in the mainframe system module; and transferring, by the front-end interface, a system control to the mainframe system module through a control transfer processing unit of the back-end interface so as to drive the mainframe function on the mainframe system module.

Abstract: An electronic device according to the present disclosure may include: a housing including a substantially transparent plate that includes a first surface facing in a first direction, and a second surface facing in a second direction; a display exposed in the first direction; and a camera device exposed in the first direction. The camera device may include: a barrel structure including a side wall defining a space therein and an opening facing the first direction and a camera housing structure including a side portion surrounding at least a portion of the side wall of the barrel structure and an upper portion facing the first direction. The camera housing structure may include a first protrusion formed on the upper portion. The present disclosure implements a waterproof/dustproof structure for capping at least a portion of the camera device.
