eye-tracking equipment

Is it possible to track eye movements using ordinary PC camera and
appropriate software or is it necessary to use special hardware ?
Results don't have to be very precise, I need them just for school
researches.

Depends on what you are trying to do. You at least need image processing
software that can track the center of the pupil. If you need to do this in
real time, it would be difficult without specialized hardware.

Well, I don't need to track eye movement in real time but I have to
measure the time while the participant of the experiment looks on the
image, that is demonstrated to him. Can I do this without specialized
hardware? I also don't need the exactly trail of pupil's move, but it
would be great if I could find out which parts of the shown image have
the biggest gaze frequency. Is there any software that requires only
PC camera and can do things that I've wrote about?

If you don't need to do this in real time, you shouldn't need specialized
hardware. You will, however, need some pretty good image processing
software. Unless you're a really good programmer, or have access to a
good image processing library, I'd wager that the commercial packages are
the way to go, especially if you need both horizontal and vertical eye
movements. If you could get away with only horizontal, there are other
options which would be much easier.

apple macs are good 4 this sort of stuff, trust me
stay away from windows

Let's presume that I need just horizontal eye movements. What other
options exactly do you mean?

Unfortunately I have access just to windows, but if I could get apple
mac, do you know any particular software that would be useful in this
case?

Electrooculography (EOG), or infrared oculography. With either system,
you'd need a way to acquire analog electrical data.

I'd imagine you could put together a good EOG system for less than $100.
Something to sample your data might run you $400 or so.

i think a good software is 'final cut studio 2' although you might
need to interweave use of one application with another if you want to
do things nicely. this isnt the best place to ask about these things,
go on to the image processing forums they'll tell you how to do it all

which subject do you need this research for?
