Description About Fitts Law Experiments

We are using the software from Scott Mackenzie’s home page.    These instructions come from the PC version. To run the program – go to the ‘This PC – downloads and click on GoFitts.  This will then give you an option to pick 2D or 3D Fitts (already selected) or some other things. Pick the 2D or 3D which will take you to the page shown under this window – and press SETUP which will take you to here:

1D And 2D Image

This is the setup page.  Students will need to make some entries here – each time a new participant comes they will change the participant number for example.  Here they will also label their two conditions 1 and 2, they will also add a group identifier for their TEAM and a session identifier for the tutorial class (I will add details in this in the slides).  On the laptop – here is where the students pick 2D or 3D. 

A participant therefore enters (or the experiment manager) their P, C, S, and G data and picks either 2D or 3D.  They then press okay and the experiment starts and runs merrily. Once the experiment ends the participant sees this feedback.

At the same time – two log files are created and they will be written to the download folder on the laptops, The second participant goes through the same process adding new participant data, etc.  

Once the experiment is over the team have to MERGE and then EXTRACT the data.  I suggest they use the sd2 data but they are free to collect up both if they want to.  This shows how this is done. Note that a full set of instructions can be found by clicking on the View API in browser on the grey set up screen that you meet at the start of the study.

Merge SD Files

Save the merged log file as a CSV and then open excel and import it as follows.
