PURPOSE: A system and a method for analyzing a posture is provided to correct a measured foot pressure value by using a representative basic foot pressure value. CONSTITUTION: A basic foot pressure value is measured at an arbitrary interval(S11). A representative basic foot pressure value is calculated(S12). A foot pressure value is measured by a pressure sensor(S13). The foot pressure value is corrected by using the representative foot pressure value(S14). The foot pressure related value is calculated. The foot pressure related value is used for analyzing the posture of a pedestrian. The posture of the pedestrian is analyzed by using the food pressure related value(S16).

Abstract:
A sensor gateway apparatus based on a ubiquitous sensor network, a system for providing an application service by using the same and a method for providing user circumstance information based on the ubiquitous sensor network are provided to prevent information loss due to unexpected communication disablement and reduce development costs. A sensor data collecting unit(24) collects sensor data about circumstance information of a user measured with at least one sensor adhered to the user or a thing. Sensor data are transmitted to a data management unit(21) from the sensor data collecting unit. The data management unit extracts sensor data corresponding to a predefined data format, a user profile and requirements according to a query of an application service system. A transceiver(27) receives the query of the application service system. The transceiver transmits the sensor data in the application service system.
Abstract:
An apparatus and a method for recognizing person behaviors using a motion vector are provided to cope with an emergency situation effectively that may occur with an observation target person. A recognition table storage unit(11) stores behavior configuration information corresponding to an average motion vector. An image collecting unit(12) collects images inputted from the exterior. A motion vector calculating unit(13) recognizes an object from an image collected by the image collecting unit and calculates motion vectors of the object. An average motion vector calculating unit(14) calculates an average motion vector with respect to the motion vectors calculated by the motion vector calculating unit. A behavior recognizing unit(15) searches the recognition table storage unit with the average motion vector calculated by the average motion vector calculating unit to recognize a corresponding behavior.
