I do recall the last time I used MathCAD that
the process of entering formulae was "WYSIWYG"
but it was also VERY tedious to do. (Click on
the symbol you want. Then click on where the
little boxes where you wanted to put the
numbers. Then click on....)
By contrast I recently picked up an HP graphing
calculator for the first time and found entering
forumlas MUCH easier once I got used to it.
Perhaps such programs need an interface that's
more "keyboard" based than "mouse" based?
And it would be interesting to experiment
with a pen based version. I wonder if anyone
is doing anything with programs like MathCAD
and tablet PCs and/or PDAs? That might be
an interesting research project.
