Hi,

One of my professors bought a keyboard of yours and I'm trying to figure out how I can look for a difference vs. a standard USB keyboard. Right now I'm using MATLAB and the psychophysics toolbox, using the following script:

t1=GetSecs();
cycles=100000;
for i = 1:cycles
KbCheck();
end
t2=((GetSecs()-t1)*1000)/cycles

t2 for the empirisoft keyboard is .11
t2 for the regular USB keybooard is .10

please let me know if any of this is unclear, but I can't seem to find a difference right now. any ideas?
