ABSTRACT:
A pen-based circulator recognizes handwritten input. The calculator comprises a display simulating a sheet of paper, and a stylus simulating a pen. The user writes a calculation on the calculator as if it were a piece of scratch paper. The calculator uses handwriting recognition to identify the various elements of the calculation, performs the calculation, and then displays the result at an appropriate location.
