Eyetracking

Background

The article talks about using your eye movements as a cursor on the screen and have it as a new and different interface rather then just using the mouse.

Discussion

The concept of using your eye movements as a mouse is good idea and I can see how it can be used as a complement to the mouse because it would be much faster to use your eyes instead of a mouse. But I do not think that it will or can replace a mouse. There are many reasons for this, one of them is that you would not be able to highlight anything with using you eyes, unless you were holding a button, and looking at the screen with precision depending on the text size. Also, you would have to constantly be looking at the screen at some fixed point, which could harm your vision. Finally, you would have to be concentrating with your eyes instead of just glancing at the screen. A possible solution to this would be to design an interface that would allow you to be able to switch between the eye motion capturing and the mouse.

The article also stated that it uses a timer in order to pick what the user wants to do. That is a good idea since that have done studies to show what is a good time to start executing what they are looking at and not, but what about the cases that someone is sitting there and dwelling on the idea and really thinking hard about whether or not they should do the action. That would cause a problem, because then the user would have to look away, and consciously know that they would have to do that if they wanted to think about what they were doing.
