I believe I read a paper by Mann that didn't use gaze tracking per se, but rather a camera mounted on the headwear itself would be used to recognize people and places. The camera would be effectively in the middle of the glasses you wore, so it captured a fairly wide angle of vision in front of you. The whole apparatus was programmed such that you could store images of people or objects in a database and access them wirelessly.
The whole point wasn't that you had to rely on you gaze anymore - the camera was always on and seeing everything in its field of view. If something or someone came into its view and the software successfully completed a pattern match, then the heads up display would display a note showing the object (e.g. putting a persons name above their head). In this sense, you could be focused on something else and the computer finds an object for you and brings it to your attention. You could look towards a large crowd of people and the computer would find your friends in there before you could. This could be expanded by adding additional cameras/sensors around your head, giving you eyes in the back of your head. A new sense if you will, augmenting your existing ones. Cool stuff for sure.
