Glass shows off what options users have available, ranging from taking pictures, engaging in a Google Hangout, recording a video, or sharing with others.Reminders
Glass can pop up a reminder on your screen to, well, remind you of an upcoming appointment or other meeting that you have planned.Weather
Like one of the cards that pops up in Android, Google Glass hopes to be able to deliver to you the current weather.Dictate Texts
There's no reason why Glass can't be used to dictate texts or short messages to others, using the built-in microphone, Google's cloud-based speech recognition, and a wireless connection.Travel Alerts
I've never seen an alert when a public transportation link has been severed or is inoperable, but I assume Google has the capability to do so. This would be a handy feature.Maps
I'm not sure a "full-screen" overlay would be the most ideal rendering of map data, but this would certainly be a handy feature to have in most cases.Turn-by-Turn Directions
One of the handiest features of Google Navigation is turn-by-turn directions. In this case, a visual direction mixed with a street name is a helpful feature.Interior Maps
Another capability that Google has added to its mapping capabilities, although it depends on the merchant - Strand Books, in this case. But yes, Google users can navigate indoors, as long as the augmented GPS (GPS+Wi-Fi, to determine location) knows where you are.Latitude/ Sharing Location
Using Google Latitude, Google users can share their location with one another. It's sort of a pain, and usually involves manually setting it up and then turning it off, to maintain some privacy. Perhaps in the case Glass automatically shares location, knowing that both of you want to meet up?Photos
Naturally, Google Glass users can take photos. This is in Glass today, although the photos (unsurprisingly) seem to have rather poor quality compared to even a mobile phone camera.Hangout (With Screen Sharing)
A nice touch. With Glass, there's every reason to believe that not only could you join a Google Hangout, you could share what you're seeing. In fact, with no self-facing camera, that might be the only way to communicate.sources: pcmag.com
