Abstract: The present disclosure relates to a method of automatically managing an emergency in a mobility device and system for the same. The method includes distinguishing passengers through an image obtained by an image sensor and determining a violent situation based on per-passenger joint position tracking, determining emotional states of one or more passengers through voice obtained by a sound sensor, based on determining the emergency requiring an emergency measure based on the determination on the violent situation and the determination on the emotional states, storing the image of the image sensor and the voice of the sound sensor, and transmitting a signal for the emergency measure to an emergency measure server.

Abstract: Disclosed are systems and a methods for monitoring a back seat in a transporter based on a head up display (HUD), the system a back seat display mounted on the back seat, and the HUD to display monitoring information selected by a user, image information filmed by a camera, and control information for an image displayed on the back seat display, and a processor configured to transmit and receive a control signal between the camera, the back seat display, and the HUD, and control zoom-in or zoom-out of a first area of the HUD where the monitoring information is displayed to not overlap a second area where driving control information is displayed, wherein the image information comprises an image content displayed on the back seat display, a reproduction time of the image content, and a number or a reproduction time of image contents after a point in time.

Abstract: Disclosed is a composite for forming a coacervate interfacial film. The composite for forming the coacervate interfacial film contains a cationic hectorite nanoplate-shaped particle structure containing a hectorite nanoplate-shaped particle and a cationic surfactant coupled to a surface of the hectorite nanoplate-shaped particle, and an anionic cellulose nanofibril containing an anionic functional group in at least a portion thereof, in which the composite may form the coacervate interfacial film at an interface of an oil phase and a water phase through electrostatic interaction between the cationic surfactant and the anionic functional group.
