tracking/pursuit task

[Cognitology]

Hi Kate,

You might have a look at my “virtual mirror” experiment:

I think it should do more or less what you want (I recommend a digital pen though, more accurate than a mouse), with target tracking, error terms, perturbation effects. 

 

Best,

Michiel Spapé

Hi Everyone

this is basically an ask for some big help or advise. 

I am very new to making Eprime tasks and have only ever used e-objects to create the basic tasks I've needed but I suddenly need to make something that is way beyond my skills and I think is probably going to require scripts and the "canvas" which I have only just learnt existed.

 

I'm trying to make a task in which I need participants to use their mouse to track a moving target on screen (a pursuit task) while they simultaneously listen to a audio file (or a series of individual audio files) that gives them a list of things they'll need to remember in a later memory task.  I can run the audio task easy enough and I've found the Dual Task sample on the PST site so I think I could get two tasks working together but I'm really struggling with the tracking/pursuit task.

 

I've seen Track Mouse Coordinates sample but I feel like I just don't understand it enough to be able to adapt it and it would only do half of what I need (would track mouse position but not target position and the difference between the two is what I'm interested in).   I was wondering if anyone knows or an example of a tracking task/pursuit task like the one i'm trying to make or has made one before and could offer any help.  I'm starting to wonder whether what I really need is 3 tasks running in parallel 1) the auditory task, 2) track the mouse cursor location and 3) presenting the target dot moving around the screen.

 

Any help or advise anyone could offer would be hugely appreciated.

 

Thanks

Kate
