I think the biggest problem is this swiping thing. Imagine Apple had released the first iPhone with a mouse plugged to it. It's a pure betrayal of the original Glass vision, where all user => machine communication goes through voice.

Voice-only is the hardest HCI problem left. Just consider the challenge as an English speaker, with 18 years of experience, of traveling from Alabama to New York to London and Wales and Scotland and Ireland to Mumbai and Kerala to Cairns and Sidney and Auckland.

True, but in the case of Glass the speaker is always the same (it's the owner) so you can learn and adapt the acoustic model over time. I'm wondering btw if Google doesn't do that already for Android's built-in speech recognition, which accuracy is amazing.

The other problem is that apps cannot (at least for now) change the language model, so Glass will always be in either "search" or "dictation" mode.

Wouldn't the hardest HCI problem be a direct cortical interface?

I really want to see glass interact with your phone so that you can perform minute actions like pinching and zooming or turning on certain camera features with your phone still in your pocket.

The touch pad on the side of the glass is multi-touch-capable, so it can detect pinch and zoom. You can't use this function via the Mirror API, but you could do it by side-loading an APK.

But then people see you touching the side of your head. Personally, I'm hoping for a ring controller.
