e-prime, digital pen or touchscreen as writing tool

[Tania]

Hi everybody!
I wont to ask you if there is a technical solution for my experimental
problems. I have to conduct an experiment with a writing tool and e-
prime. I don’t know if e-prime can interact with a digital pen or a
touchscreen. My subjects have to write a word in different part of the
screen and I need to register the reaction time of starting to write
and/or the duration of the writing. Is it possible?
I have never used e-prime but I think I have to do this experiment
with it and I need a good reason and the assurance to find (and
eventually buy) the right instrument.
help me!please!

Hi Tania, list,
As written elsewhere, it is perfectly possible to use touch-screens, and
especially tablet-pens, in E-Prime. However, E-Prime will consider it as
exactly the same as a mouse-cursor (see my earlier message on this topic by
searching). This means that if you can design your experiment in E-Prime
with a mouse, you can later always use a touchscreen. However, you will have
to think really carefully what you will be recording and what you want from
the data: if a person lifts the pen for 100 ms, does this count as an "end
of writing", or is it merely a pause? What do you want to record? Pen
positions for every 10 ms, to later do FFT over? I don't know, but I can
tell you that it will be much trickier than you think to just record
"duration of the writing". Moreover, while, as said, it's possible in
E-Prime, it most definitely won't be all that easy - it's quite a leap from
the core business of E-Prime: experimental psychological experiments like
priming, stroop, recognition, visual search, and so on, tasks, that require,
above all else, really solid timing. Quite likely, you'll find many other
packages to be of much better value for money.
Best,
Michiel
