Monitor mouse clicks during a movie

[I][edited from support email][/I]

I am setting up an experiment that needs reaction time measures of the mouse at every click of the mouse when it is being used within another embedded program (a media player). I also want to measure the number of mouse clicks while the participant is performing the experimental task.

Can I do it within MediaLab? Our lab now has MediaLab as well as DirectRT (latest versions). I understand from earlier conversations that InputRT can help here. Firstly, is InputRT to be separately installed? And secondly, can I run InputRT from Medialab straightaway or should I do it only via a DirectRT session?

You certainly could try using the InputRT program that comes with DirectRT. I would run it in combination with DirectRT but you could also run it with MediaLab. In any case, InputRT is here (see link below) and you can get a code for it if you are a licensed v2006 DirectRT user:

One way to do it: You would start InputRT before the DirectRT session. You could present an instruction screen instructing the subject to click the left mouse button to start the movie. InputRT will record that click and will consequently give you a reference point in the InputRT data file so you'll know at what point the movie started.

Hope that makes sense. Let me know how it works out if you try this!
