Eye tracking cameras are some of the coolest pieces of equipment used in Human Factors Engineering and Usability.

How much do eye tracking cameras cost?
Eye tracking cameras aren’t easy to come by. I’m not sure how much they cost, but I know that they are expensive!

How do eye tracking cameras work?
Eye tracking cameras are often mounted to the top of a computer screen. They are able add cross hairs to the computer display screen so that observers can monitors where the user is looking. The one I used several years ago was a little jumpy, and required a lot of adjustments.

I’m sure the technology has drastically improved since the last time I’d user them. I’d love to try one out today.

What good are eye tracking cameras?
Eye tracking devices are great for testing the usability of graphical user interfaces. For example, if a use case involves the user clicking on a series of several buttons, the eye tracking camera can map where the user’s eyes seek to the find the desired buttons. It is very valuable to know if the user is reading, or seeking a button.
