| Zusammenfassung: | Abstract: "Creating and changing a drawing with one of the current interactive drawing programs, e.g. MacDraw (Apple, 1984), Illustrator (Adobe, 1987), Freehand (Aldus, 1987) or Gargoyle (Pier, Bier and Stone, 1988), is not easy when the number of objects becomes large. From psychological theories of visual perception it is known that humans reduce a large number of objects by perceiving groups of objects as single objects (Koffka, 1935; Miller, 1956), which implies that the mental representation of a drawing has a hierarchical structure (Buffart, 1986; Palmer, 1977) Although the current drawing programs do allow the user to create a drawing with a hierarchical structure, only the objects at the highest level of the hierarchy can be selected and edited. This paper presents a different approach which allows the user to select and edit objects at each level of the hierarchy. The main concept, a current object, allows the user to travel through the hierarchical structure of the drawing in order to select objects at each level of the hierarchy. This approach not only enables the users to use the hierarchical structure that corresponds to their mental representation, but also eliminates some inconsistencies in the current drawing programs A drawing program has been made in which the proposed way of structure editing has been realized. The first impressions of this implementation will be discussed. |
