Some configurations were applied to fit the screen according to the paper this experiment is based on. 
20 11 Davíð Örn Jóhannesson
The screen is a DELL: 1905fp - series [approx 41.5x41.5 http://reviews.cnet.com/lcd-monitors/dell-ultrasharp-1905fp/4507-3174_7-31232074.html ]

In order to convert we assume the following:
23 13 Davíð Örn Jóhannesson
* Box in degrees 1.8 x 2.3
24
* Distance from screen: 0.6 m
25
* Box: 2.86 x 2.45 cm*
26
* Using "http://www.unitconversion.org/typography/pixels-x-to-centimeters-conversion.html" we get
27 12 Davíð Örn Jóhannesson
* Pixels: 108 x 92

/* The calculations are size = 2*(length from screen)* sin[(given angle)/2]</b>

h3. How to run
32
33
To run the test, download python version 3 or later (preferably version 3.3.1), download the .zip file (currently unavailable), extract the .zip file in a directory of your choice. Run the "Run_experiment.py"(currently unavailable) script. 
34
The files created in the test are created in the same directory as the "Run_experiment.py" file.
35
36
h3. How it works
37
38
After running the file to start the program (see: "How to run") you are prompted to enter subject number from 1-99. 
39
The program then checks if the name is taken, if not taken it creates a directory in the same directory you keep the the program. If the number is taken the program prompts a question to ask if you want to overwrite the folder, choose "y" for yes and "n" for no. If "n" is chosen then the program will exit.
40
41
Assuming that you have a legit file name and the directory has been created the test will begin.
