My niece needed a piece of simple software to measure reaction times for a school research project. Apparently, it isn’t that simple to find a simple tool to accomplish that, so i made something in an afternoon that runs in a browser she could use.

The reaction test goes like this: after clicking ‘start the test’ ten random items appear, either a small image or a sound. You then need to press the spacebar as fast as you can. After the test is over a scorecard appears with your reaction times in miliseconds.

The application should work in Firefox, Opera, Safari and Chrome. I haven’t tested it in some other browsers (*cough* Internet Explorer), so if it doesn’t work try Firefox.

Try a demo, get the code here as a zip or check out directly from Subversion.
