The knowledge product trading method as an operation method of an online knowledge trading system includes providing a knowledge authoring application (app), collecting knowledge from a knowledge provider through the knowledge authoring app, providing a knowledge service app, receiving a knowledge query request from a knowledge consumer through the knowledge service app, and selling the knowledge collected through the knowledge authoring app in response to the knowledge query request.

Abstract: A system for providing virtual AV service includes a local device middleware (LDM) media server which stores AV contents and a resource cooperation server (RCS) which separates the AV contents from the LDM media server into video contents and audio contents. The video contents and the audio contents are reproduced by an LDM video renderer and an LDM audio renderer, respectively. An LDM control point (LDMCP) controls the LDM media server and the LDM media renderers using the LDM protocol and a virtual device ensembler (VDE) controls the RCS and the LDMCP.

Abstract: There are provided a device and method for supporting an external device I/O using a mobile communication terminal that the mobile communication terminal held by an individual may be used as an I/O unit of the external device, which is driven by the external device, for example, a kiosk and a digital signage, rather than driven by the mobile communication terminal. Further, a plurality of users may simultaneously perform I/O of the external device using each of the mobile communication terminals held by the plurality of users.

Abstract: Disclosed are a wearable mobile phone capable of detecting EMG changed by hand motion of a user and a control method of an input unit of the wearable mobile phone. The wearable mobile phone includes an EMG measuring unit 10 having a plurality of EMG measuring sensors 11 for detecting the EMG changed by hand motion of a user, and made in a ring shape to be worn on a wrist of the user, an EMG transferring unit 20 connected to the EMG measuring unit 10 for transferring the EMG measured by the EMG measuring unit, an EMG determining unit 30 mounted to one side of the EMG transferring unit 20 for receiving EMG from the EMG transferring unit to determine the hand motion and extract an input signal for the mobile phone corresponding to the hand motion, and a mobile phone functioning unit 40 receiving the input signal from the EMG determining unit for functioning the mobile function and having an antenna and a sound transferring device.

Abstract: A biological signal measuring apparatus includes a first biological signal measuring sensor attached to an earphone used for a mobile phone; and a biological signal receiver for receiving a biological signal from the first biological signal measuring sensor to thereby generate first raw data. The apparatus may further include a second biological signal measuring sensor attached to one of the mobile phone and an adaptor connected to the mobile phone, wherein the biological signal receiver receives a biological signal from the second biological signal measuring sensor to thereby generate second raw data. The apparatus is provided with a controller for detecting whether the mobile phone is used, wherein the controller drives the first and the second biological signal measuring sensor to measure the biological signal when the mobile phone is being used, and stops measuring the biological signals when the use of the mobile phone is finished.

Abstract: Disclosed herein is a bio-signal measurement system for measuring bio-signals and providing relevant health care service. The bio-signal measurement system includes a bio-signal measurement device and a portable terminal device. The bio-signal measurement device is formed in a necklace shape, and is configured to measure various bio-signals, perform signal processing on the measured bio-signals, and send the processed bio-signals through a short-range wireless communication module. The portable terminal device is configured to perform signal processing on the sent bio-signals, store the processed bio-signals, calculate relevant bio-indexes, provide a monitoring service related to the bio-signals, compare the calculated bio-indexes with previously stored bio-indexes, and selectively provide a relevant health care information service.

Abstract: A wearable apparatus for converting a vision signal into a haptic signal, an agent system using the same, and an operating method thereof are provided. If a blind person has a vision signal processing module mounted on glasses and a haptic signal processing module wore on a skin, it can be very useful for the blind person because a guide for a white cane and a voice guiding service can be provided through a network. The guide for the white cane is performed by adjusting various heights and vibration intensities of pins of a matrix according to a Y component extracted from an image of surroundings.
