While Glass’ best known interaction method is the verbal "Okay, Glass" prompt, most of the UI can only be operated by swipes and taps.
Outside of the homescreen, the only time you’ll be speaking is when you’re composing a text reply to a card in your timeline (like an email message, or a tweet).
You simply click the "on" button and the app will come alive.
If you want other apps, there’s no app store to go to — you’ll have to hunt them down and install them yourself. Google’s Android app for Glass doesn’t offer anything beyond the web app in terms of device management, but it does include two very important features: tethering and mirroring.
From there you log in to your Google account (@addresses only, for now), and begin a breezy setup to pair your device to that account.
It's also easy to overload your Glass with contacts and apps, and since deleting cards from your timeline is a pain, you want to make sure all your incoming content is quality.
We recommend you do the setup from a computer, because the next step is a pain: adding contacts.
And that it’s the right version of that contact — it’s all a little mysterious, but you’ll know you’ve got the right one if a profile pic shows up in My Glass.
Even then, Glass won’t play nice with everybody: for instance, the voice recognition won’t register "Jordan Oplinger" no matter how hard we try.
