touch-screen Experiment

[antonio.pellicano at unipd.it]

dear All,
I'm hardly trying to write a dual-choice-reaction-task using a
touch-screen as a response device.

The exeriment must collect Reaction Times and Movement Times from each trial.

A single trial consist of a home box-square and two lateral target
box-squares drown on the monitor display.
Subects have to discriminate between two stimuli by releasing the index
finger from the home box and touch the left or right target box.
Releasig time will be the RT, while the interval between the release of
the home box and the touch of the target box will be the MT.

Is there anyone who is familiar with similar experimental designs?

Is there anyone of you who interfaced a touch-screen device as a response
device to E-Prime?

Than you very much in advance
