THREE DIMENSIONAL INTERACTION DEVICE AND METHOD OF DISPLAYING AND DETERMINING USING THE SAME

摘要

PURPOSE: A three-dimensional interaction apparatus, a three-dimensional display method using the same, and a three-dimensional shape information decision method using the same are provided to sense a shape change of magnetic materials caused by a user, thereby generating three-dimensional shape information. CONSTITUTION: A housing includes a internal space where magnetic materials(3) are able to move in. Coils generate a magnetic field in the internal space. A controller generates a control signal for controlling the coils. The controller includes a sensor and a control signal generator. The control signal generator outputs first control signals for controlling first coils(30) in a 3D(Dimensional) shape input mode. The first coils generate a first magnetic field in response to the first control signals. The sensor senses an arranging state of the magnetic materials based on an induced current induced to a second coils(32).
