For these kinds of work I recommend using Psychtoolbox http://psychtoolbox.org/ as it is designed specifically for presenting stimuli for precise times.

pause(60);
for k = 1:20
disp('Tap');
pause(10)
disp('Rest');
pause(20);
end
The sleep command of java has a smaller jitter than the pause command:
% replace pause(duration) by:
java.lang.Thread.sleep(duration * 1000);

What exactly does "Tap in full screen" mean? "Full screen" can mean a Matlab figure with visible borders and menu bar, or without the borders, with or without the taskbar of the operating system.
