Pencept

Pencept was noted primarily for the robustness (for the time) of the handwriting and gesture recognition algorithms, and for an emphasis on developing novel user interface approaches for employing gesture recognition and handwriting recognition that would work with existing applications hardware and software.

Pencept employed a proprietary technology for on-line character recognition, based on a functional attribute model of human reading.

Early products included the PenPad 200[1] handwriting-only computer terminal that was a direct replacement for the VT-100 and other standard ANSI 3.62 terminals, but with a digitizing tablet and electronic pen and no keyboard.

With the advent of the IBM personal computer, later products, such as the PenPad 320[2] focused particularly graphics and CAD/CAM applications for the DOS operating system, as well as for data entry and data editing applications.
