Abstract: An augmented reality (AR) service clustering a plurality of markers for mapping an AR object by a device into at least one group and determining a representative marker of the clustered group, and preferentially searching for markers included in a cluster of the representative marker when a scene recognized by the device corresponds to the representative marker, is provided. An AR service generating an AR object based on data received from a user while a scene recognized by a device is displayed on a screen of the device and determining the recognized scene as a marker of the AR object is also provided. An AR service clustering a previously obtained plurality of pieces of content based on a predetermined reference and generating an AR object based on the plurality of clustered pieces of content is further provided.

Abstract: An electronic device, an operating method thereof, and a recording medium are provided. The electronic device includes a housing, a location sensor that is disposed within the housing and obtains location information about the electronic device, a biometric sensor that is disposed within the housing and obtains health information about a user of the electronic device, and a processor which is disposed within the housing, and is connected with the location sensor and the biometric sensor, wherein when a change to an emergency mode is detected, the processor controls to transmit the location information and the health information to a predesignated first external electronic device in response to the emergency mode.
