Hi Kristen, Apologies from coming late. I've had some experience with eye tracking during my scientific work and to be honest, it probably wasn't worth the effort. Eye tracking measures immediate visual focus (and not necessarily attention - it is possible that the two can be split on occasions) and it's difficult to infer from this up to the higher levels of cognition that usability work is most often concerned with. Well used (i.e., experienced analysts, good participants, an appropriate task, and suitable conditions), it can shed light on the low level features of something, but miss any of these out, and the data are probably misleading.
I used this system a while ago and cannot remember what its name was sorry, but I remember about 30% of participants being unmeasurable. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
