The Freehand Formula Entry System is a pen-based equation
editor, developed jointly between researchers at Queen's
University and researchers in New Zealand and the United States.
FFES interprets while the user draws, producing LaTeX and
operator tree output, which we hope to translate to computer
algebra system languages (e.g. Maple, Mathematica) in the future.
User feedback is given as (1) a bitmap and
(2) fonts drawn behind recognized symbols (see image to left).
