It turns out that Apple is indeed exploring such a possibility, at least that’s according to a patent discovered by Apple World Today in which the patent they found seems to hint that such a future. According to the patent, it reads in part, “In some embodiments, an electronic device optionally identifies a person’s face, and optionally performs an action in accordance with the identification.”
It also seems to mention that this system could be used not just for identification, but it could also be used to determine the user’s gaze and could perform an action based on that. “In some embodiments, an electronic device optionally determines a gaze location in a user interface, and optionally performs an action in accordance with the determination.”
This could help with accessibility where if a person is handicapped, using their eyes to look at icons on the screen to launch apps could be one way that such a system could be used. Of course, there’s no way of knowing if this patent will ever come to pass, but with Apple set to launch new ARM-based Mac computers in the near future, who knows?
