A three-dimensional motion graphic user interface includes a first polyhedron component which exists in a first space, and a second polyhedron component which exists in a second space, wherein the first polyhedron component includes identification information that identifies the second polyhedron component, and if an information object selected by a user is located inside the first polyhedron component, the information object is moved inside the second polyhedron component using the identification information.

Three-dimensional motion graphic user interface and method and apparatus for providing the same

A three-dimensional motion graphic user interface (MGUI) and a method and apparatus for providing the three-dimensional MGUI are provided. The three-dimensional motion graphic user interface includes a first polyhedron component that is formed of a plurality of faces, wherein at least one face of the plurality of faces that are subordinate to the first polyhedron component has predetermined attributes and displays information according to the attributes, and the first polyhedron component is separated into a plurality of second polyhedron components according to a user's action with respect to the faces.

A three-dimensional motion graphic user interface (MGUI) and a method and apparatus for providing the same. The MGUI includes a three-dimensional interface space which has an active space and an inactive space, and a polyhedron component which is three-dimensionally presented in the active space, wherein at least one of a plurality of faces that are subject to the polyhedron component has predetermined attributes, and information displayed on the faces is displayed differently according to the attributes and a presentation relationship between the active space and the polyhedron component.

A comparator according to the present invention can generate an output signal of low or high level by comparing a first and second input voltages that have a common voltage. An input stage circuit of a comparator according to the present invention receives a common voltage detection signal. The common voltage is supplied with a first offset voltage when the common voltage detection signal is on low level, and the common voltage is supplied with a second offset voltage when the common voltage detection signal is on high level. Then, the input stage circuit performs amplification to output a voltage difference between the first input voltage and the second input voltage to the comparator. Accordingly, the comparator with offset voltage according to the present invention can sufficiently amplify the input signal difference of low common voltage by selectively applying different offset voltages to a common voltage in accordance with the common voltage level of the input signal. The present invention can be applied to a comparator with offset voltage and an analogue comparator having a differential input stage.
