THREE-DIMENSIONAL HOVERING DIGITIZER

WIPO Patent Application WO/2016/076519

A1

The present invention relates to a digitizer and, more specifically, to a 3D hovering digitizer for controlling an image shape display by sensing 3-axis magnetic field information according to the movement of a magnetic force pen. The three-dimensional hovering digitizer according to one aspect of the present invention comprises: a magnetic force pen, which moves by being spaced from the upper part of a touch screen and generates a magnetic field around the pen; a sensor arranged on the outer side of the touch screen so as to sense 3-axis magnetic field information according to the movement of the magnetic force pen; and a control unit for receiving the 3-axis magnetic field information sensed by the sensor so as to control a shape display of a 3D image displayed on the touch screen.
