Abstract: A mobile device and operating method provides information by automatically recognizing a user intention. The mobile device includes a sensor configured to sense a user's eye movement, an event detector configured to detect an event by inferring a user intention based on the user's eye movement, an application function executor configured to execute a function of an application in response to the detected event. The mobile device may further include a display configured to display results of function execution.

Abstract: A cloud-based sensor data acquisition system includes one or more sensors configured to acquire sensor data; a first terminal configured to transmit sensor data request information to a cloud server through an access point (AP); and one or more second terminals each configured to acquire sensor data from one or more sensors on a corresponding dissemination tree received from the cloud server; and transmit the acquired sensor data to the first terminal through the AP. The cloud server is configured to, in response to receiving the sensor data request information from the first terminal, build a corresponding dissemination tree for each of one or more second terminals within a sensing range; and transmit the corresponding dissemination tree to each of the one or more second terminals within the sensing range.

Abstract: An apparatus includes a display unit configured to display a user interface screen in an area, and a sensing unit configured to capture an image of a motion of an object used to enter user input. The apparatus further includes an input recognition unit configured to lay the image over the user interface screen, and recognize the user input based on the image laid over the user interface screen, and a processing unit configured to process an operation corresponding to the recognized user input.

Abstract: A system for providing a social network service (SNS) by utilizing augmented reality. The system includes a first device configured to receive image of a first user, to create a reference image based on the received images, and to transmit the reference image to a second device; and the second device is configured to receive the reference image from the first device, to generate a virtual image based on the reference image and the current context information of a second user, and to display the virtual image at predetermined locations.
