Abstract
A figure input system includes an input device such as a digitizer through which coordinate data of points on a figure to be inputted are time-wise continuously received. These data are sampled sequentially at set time intervals and are analyzed in view of the kind of basic figure intended by the user such that geometrical characteristics and position data are extracted from the sampled data and a regular basic figure can be displayed on a display device.
