Abstract : This Memorandum describes a low-cost, two dimensional graphic input tablet and stylus developed for conducting research on man machine graphical communications. The tablet is a printed-circuit screen complete with printed- circuit capacitive-coupled encoders with only 40 external connections. The writing surface is a 10 in. x 10 in. area with a resolution of 100 lines per inch in both x and y. Thus, it is capable of digitizing 10 to the 6th power discrete locations with excellent linearity, allowing the user to write in a natural manner. The system does not require a computer-controlled scanning system to locate and track the stylus.
