DEVICE FOR INPUTTING GRAPHIC AND METHOD THEREFOR AND METHOD FOR OPERATING GRAPHIC OBJECT AND METHOD FOR SUPPLYING GRAPHIC INPUT SIGNAL

摘要

PURPOSE: To detect the operation of a user without making a user mount a specific tool, hold a tool, or be restricted. ;CONSTITUTION: A CCD camera 110 detects the fingers of a user brought into contact with a panel 105 as plural shadows. The CCD camera 110 simultaneously can detect plural contact parts generated by the contact of the plural fingers, and it is used for the detection of an input gesture. The decision of the panel 105 itself and the contact parts on the panel 105 is judged by the positions of the shadows on a video picture. Only the detection of the presence of the shadows on the panel 105 is sufficient for the function of the CCD camera 100, and only a second-dimensional picture processing is necessary. The CCD camera 110 can simultaneously process plural pictures on the panel 105, and a multidimensional input signal is generated. Moreover, this picture has large contrast, and only a processing for separating bright parts from dark parts is necessary.;COPYRIGHT: (C)1995,JPO
