Fitts' Law calculations

I created a program that dials 10-digit telephone numbers on the sample telephone interfaces. After reading in some pixel-level information about the telephones, an analysis can be run on these numbers. The analysis can dial all 10 billion possible numbers, or can dial any specific number using dialGeneric().

The program includes two versions of Fitts' Law, and more can be trivially added. Comment out one line, and uncomment the other. The file starts with this. The Fitts' constants are definied at the top of the file, with A=K=100.0 and B=150.0

time = FITTS_A + FITTS_B * (log(2.0 * distance / width)/ log(2.0));
//time = FITTS_K * (log(0.5 + distance / width)/log(2.0));

The code, the input, the program.

Be patient! The program may take a few hours to run!
