    Abstract: Provided is a dynamic network configuration and server extension system. The dynamic network configuration and server extension system includes a plurality of service servers configured to provide a request service according to a service request; and a management server configured to provide session information of a configuration which is dynamically transmitted by a buffer on a memory for the plurality of service servers providing the requested service and operate additionally the service server in proportional to the service request to extend the server. According to the present disclosure, it is possible to provide a service desired by a user (client) through a wired/wireless dynamic environment configuration method and a wired/wireless load distribution server management function.

    Abstract: A method and apparatus for motion capture interface using multiple fingers are disclosed. The method includes measuring a position of an end of a middle finger of an actual hand in a state in which the actual hand is spread, deriving a starting reference position of the middle finger of the actual hand, and calculating a length of the middle finger of the actual hand. The method further includes recognizing a relationship between starting reference positions of a thumb, an index finger, a middle finger, and a wrist based on using a virtual hand reference model that models a virtual hand to be controlled.
