For my doctoral work at Stanford I am working on developing ways to use eye-gaze to interact with computing devices. The project called GUIDe (Gaze-enhanced User Interface Design) allows you to do everyday actions of interacting with a computer using eye-gaze. You can surf the web without having to use a mouse, switch applications by simply looking at them in an expose-like view etc. For more information check out the GUIDe website.
I haven’t really been updating my personal site at all, but here is a link to some of the work I did at Stanford which was published at CHI 2005. The basic premise is that cars should be equipped with a dynamic speedometer which shows the current speedlimit on the background of the display. The technology to do this already exists today. This is just one of several approaches we developed in order to combat the issue of un-intentional speeding.
Here is a video clip which shows the dynamic speedometer in action.
In addition, here is a podcast which featured the Dynamic Speedometer research.
