Abstract
Human-computer interaction involves the movement of information between a human and a computer by means of suitably designed interface systems. Conventional interfaces for the transmission of text and other basic forms of data are now well established. Increasingly, various types of pictorial interface are being used to fabricate “user-friendly” dialogues with computers. This paper describes some approaches to human-computer communication via the use of conventional paper-based pictorial forms. Some attempts at evaluating ena-user reactions to the use of this type of interface are described. The results of the evaluation are very encouraging. Our findings suggest that this interface system is acceptable, sound, robust, easy to use and learn, and is sufficiently expressive.
