Measuring switch time between keyboard and pointing device

I have developed a program for measuring the time taken in switching
between keyboard and pointing device. It is to be used to test a
prototype of my invention which is a combination device of keyboard and
mouse. It can also be used to test for other input devices as well.
It is freely available and can be performed using a browser at this
address: http://www.timeguider.com/imouse/ptest/ It is still in beta
version and any comment will be welcome.
