@stroughtonsmith @gruber Doesn't seem to have an effect on Safari? So far everything else works.

@jamesthomson The obvious question to me (and I haven't gone through the WWDC sessions, forgive me if this is obvious) is: how do you use this? Eye tracking is awesome, but "eye + finger tap" for every single digit seems like a *clear* non-starter. This isn't your problem to solve, but I'm wondering if Apple has thought of this? Or are users expected to say "forty-two squared times the cosine of 30"?
