    An extended user interface for CAL systems
    (1990) Davenport, David
    This paper examines the problems of complexity in human-computer interaction from the perspective of CAL systems. By considering the very special demands of young, pre-reading age children, it shows how pointing type interfaces can be extended in a simple and natural manner based on the notion that the position of, and spatial relationship between objects, is of significance. Various examples based on this extended interface concept are introduced to demonstrate its functionality.
