  • Patent number: 7693333
    Abstract: A portable terminal and a user interface control method thereof are provided. In the terminal and method, patterns of a subject image captured by a camera are recognized and analyzed. First and second images changed according to motion (movement, holding away from or drawing close to a user) of the portable terminal are captured by the camera module. Patterns of the first and second images are recognized. The motion of the portable terminal is analyzed based on the recognized patterns. Control commands corresponding to the analyzed motion are selected. A function corresponding to the selected control command is performed. The portable terminal can be intuitively and simply used as its motion is directly applied to user interface control. User interface can be controlled without an additional part, using a camera installed to the portable terminal. Also, the present invention can resolve the problems caused when the conventional navigation key is operated.

  • Patent number: 7020542
    Abstract: An apparatus for measuring and fixing the three-dimensional location of medical instrument that can be easily placed at a desired location by a user. In addition, a medical apparatus for measuring the three-dimensional locations of an apparatus fixed at an end portion of a cancer and an external apparatus and fixing the apparatus at an end portion of the cancer, which can be easily placed at a desired location by a user and carries out the location-fixing and measuring at the same time. The apparatus is applicable for various medical fields such as the measurement of the location and orientation of an external apparatus, the measurement of relative locations of a medical instrument contacted to an end-portion of a cancer and the object body, and the fixation of the instrument at a desired location.
