Patent ID: 8144169

Claim:
An input device for graphics, suitable for editing a 3D model displayed in a screen, the input device comprising: a signal transceiver module, for communicating with a graphic system to obtain an information of the 3D model, wherein the signal transceiver module comprises a first transceiver and a second transceiver respectively disposed at a first location and a second location of the input device for obtaining a plurality of spatial information of the input device; a telescopic sensing component, coupled to the signal transceiver module, wherein an expansion of the telescopic sensing component reflects a force of the input device applied to the screen, and a length of the input device is adjusted according to the force; wherein the signal transceiver module transmits the expansion and the spatial information to the graphic system to allow the graphic system to generate a virtual object in the 3D model for simulating a state of the input device merging into the screen; and a pressure sensing component, coupled to the signal transceiver module, wherein the pressure sensing component adds a material into the 3D model when the pressure sensing component receives an input instruction.
