This post strives to be a comprehensive, up-to-date list of what cool things Glass can do, to help answer the common question people ask me: what does Glass do?
Hopefully, it will also contain a couple of tips/tricks newer Explorers may not be aware of.
Glass shows a small square in the top-right corner of your vision. It's transparent and only there when you tip your head up or touch the side.
You can say "Ok Glass" or touch the side to navigate the menu options.
"Google..." will search for what you say. If it's a contextual question, like "Ok Glass, Google, do I need an umbrella tomorrow?", Glass will reply to you, similar to Siri.
Conversational search is a neat feature here. Some examples:
"Who is the president of the United States?" "How old is he?"
"Should I wear a jacket today?"
"Do I need an umbrella tomorrow?" "How about this weekend?"
Google can also translate sentences, i.e. "say Hello in Chinese"
Take pictures by winking, saying "Ok Glass, take a picture", or pressing the shutter button.
Take video by saying "Ok Glass, take a video", or holding the shutter button
Send pictures, view and reply to text messages, make phone calls
Video call people on Hangouts
Get directions to places via walking or driving
Glassware (the official apps)
Translate words you see by saying "Ok Glass, translate this..." and looking at a word. The old word is blurred out and replaced with the translated one.
Evernote syncs with your Evernote account and makes quick notes.
Allthecooks Recipes lets you cook and see the recipe, without getting junk on your paper or phone.
Compass is a neat heads-up display
Stopwatch and Timer do exactly what you'd expect
Google Now will tell you the weather, traffic information, news, etc., on your timeline.
Things to point out
Glass only covers part of your vision, and really only when you look at it. By default, the screen is off, and even when it's on, it's a blur in your peripheral when you're not glancing at it. Much safer than looking down at your GPS unit, ahem.
Glass can have earbuds attached to it, but without them, it uses a bone-conducting speaker that sends sound waves into your ear. Physics.
Prescription (or even blank) lenses can be attached to make them look more natural.
The device is beta and a lot of cool new features are on the way.
No, we're not recording you. The battery life is too short for that.
Subject to be updated as I discover more, or as Glass is updated.
tl;dr: It's a super easy to use smartphone on your face.
