## [BSM+88]  Charcoal Sketching: Returning Control to the Artist

 Bleser:1988:CSR (Article) Author(s) Bleser T., Sibert J. and McGee Title « Charcoal Sketching: Returning Control to the Artist » Journal ACM Transactions on Graphics Volume 7 Number 1 Page(s) 76--81 Year 1988

 Abstract Background: Traditional paint programs can be criticized on the grounds that they provide fewer degrees of freedom than conventional artistic media. Mouse or tablet input devices usually provide only (x, y) spatial information. Thus most paint programs allow continuous control of the path of a stroke, but render it with a single "brush shape" of fixed size and orientation and use menus, either stationary or appearing, for such tasks as changing "brush" shapes. This produces two distinct discontinuities for the artist. First is a physical discontinuity: stopping the act of drawing and making a brush selection using a different physical device, or using the same device to point at a menu selection. A second discontinuity is the cognitive one involved with deciphering the menu contents and making a selection. Although the second may be minimized by using iconic menus, these interruptions of the drawing act make it difficult or impossible for the artist to maintain the kind of continuous control over his or her medium that is required.
