Eyetracking

Review

This article looks into the auxiliary method of using eye movement as an input and discusses the experiences and observations that they find.

Discussion

I like how they talk about how the bandwidth when interacting with a computer is one sided. That the computer feedback to the user is far greater than the opposite. More than anything this shows what future techniques might be, and that is to say in the future interaction techniques will give the computer much more data. The graph that shows the users eye movement over 30 seconds illustrates this.

Saying that eye tracking could be a replacement for the mouse is a little bit of a strain. Having them interact in unison is more applicable. In the future after users are trained and more accustomed to using eye movements it might be possible, but certainly not in the immediate future.

Most of the techniques described are extremely inconvenient. New user techniques need to impose nothing new on the user. Having to put on an "eye patch" to use a computer is not convenient in the least. Future techniques in this area need to be focused on methods that are able to recognize eye movements with out imposing on the user, such as strictly using cameras.
