<p><P>PROBLEM TO BE SOLVED: To manage and modify stroke width to reflect user intention. <P>SOLUTION: A system varies hand-drawn line width as a function of geometric or temporal properties such as a curvature or time of the strokes as the user draws them. The system includes a stroke control module, a velocity adjustment module, a curvature adjustment module, a smoothing module, an adjacency verification module, and a stroke dominance module. The stroke control module modifies the width of input strokes and adjust them based on their curvature and/or the velocity at which they has received. The stroke control module cooperates with and controls the velocity adjustment module, the curvature adjustment, the smoothing module and the other modules to provide overall width adjustment of strokes input by the user to automatically reflect the needs and intentions of the user and provide a natural-feeling drawing experience similar to that provided by paper. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
