The idea of using graphic symbols as a means of or support for communication or in more general terms as a picture word processor, appears to be on the increase.
The designers initially started out to create an effective picture system and a handy aid to call up pictures quickly and efficiently. The nature and the build-up of the system has thus come from the objective. The Beta system was developed as a visual, communication-supportive system, from the conviction that there existed a void in the variety of systems that in general were found to be too abstract or to systematic. In fact, the system wasn’t developed as a means for communication as such, but as an instrument to develop communication aids. That doesn’t mean that a lot children and adults cannot learn to work with the system. It has proved to be a very useful tool in language teaching since Beta is also available in French and English.
