Abstract: A portable apparatus and a method of changing a content screen of the portable apparatus are provided. The portable apparatus includes changing a displayed content in response to an increase in a visual fatigue and a method of changing a content screen of the portable apparatus. Some of disclosed various embodiments provide a portable apparatus that calculates a visual fatigue by using user electroencephalogram (EEG) information received from a wearable apparatus and changing a displayed content into another content in response to an increase in the calculated visual fatigue, and a method of changing a content screen of the portable apparatus.

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, a wearable device, and a controlling method thereof are provided. The method of controlling an electronic device according to an exemplary embodiment includes receiving a touch command with respect to an object displayed on a display screen, generating an inductive current based on a signal pattern corresponding the object for which the touch command is received and the electronic device, and transmitting the inductive current generated to a wearable device through a user who touches the object. Accordingly, an exemplary embodiment may minimize or reduce procedures for user authentication at a terminal or a service.
