ABSTRACT:
A Bicameral Keyboard is provided for generating pictographic characters wherein twenty keys are sufficient to specify the roughly 3000 characters required for ordinary personal and business correspondence. The Bicameral Keyboard is compatible with pictographic expression and pedagogy and will permit direct access to word processors, translation machines, page editors, and printers at input rates more rapid than possible using the alphanumeric keyboard with western orthographic characters.
