It does have value as a secondary diagnostic tool. In the context of usability testing, eye tracking does not determine the presence of a usability problem, but helps determine what led to that problem in conjunction with performance data, faciliator observations and user self-reporting.
For example, different people may fail a task for different reasons that eye tracking can reveal - overlooking a critical instruction versus reading it but failing to understand it. In some cases users can tell you this reliably, in others they can't. Also, eye tracking provides a comparative metric between designs that are equivalent on other performance measures. For example, Design A may require greater visual scanning or workload than Design B, so all other things being equal, Design A might be the better option. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
