MOBILE DEVICE FOR DISTINGUISHING USER'S MOVEMENT, METHOD THEREFOR, AND METHOD FOR GENERATING HIERARCHICAL TREE MODEL THEREFOR

摘要

The present invention relates to a mobile device for distinguishing a user's movement, a method therefor, and a method for generating a hierarchical tree model therefor. Particularly, the mobile device includes: an acceleration sensor; a buffer for collecting the acceleration data outputted from the acceleration sensor according to a user's specific movement; an extraction unit for extracting the characteristic elements of the user's specific movement based on the acceleration data collected by the buffer; and a movement judgment unit for determining to which class the user's specific movement belongs by inputting the characteristic elements extracted by the extraction unit into a pre-structured hierarchical tree model, wherein the hierarchical tree model is pre-structured based on the characteristic elements extracted for each movement, and the characteristic elements of each movement are extracted based on a first frame group formed by dividing the acceleration data collected for each movement by a predetermined time unit and a second frame group formed by dividing the acceleration data collected for each movement by another time unit different from the predetermined time unit so as to cause a part of the acceleration data to overlap the first frame group.
