Users’ Analysis and Criticism of Abstract-Graphical Pictures

The stage has now been set for a study of ways in which end-users of interactive systems can work with abstract-graphical pictures. Having shed light on how users understand pictures (Chapter 4) and mechanisms for using pictures to convey information (Chapter 5), we now want the user and the computer to join forces via the pictures presented. In order for abstract-graphical pictures to link up the user and the computer effectively, we need convincing ways in which the user can close the circuit by giving his or her input a new quality with respect to the pictures.
