- Engineers are currently 'experimenting' with connectivity options. Existing prototypes -- including those worn in the skydiving stunt this morning -- do not have any sort of built-in WWAN connectivity.
- While it's possible that a 3G / 4G module could end up in production devices, the general idea is that latching onto nearby WiFi hotspots or relying on a wireless tether with your smartphone will be the primary way that Glass gets its data to the web.
- Controlling Glass will eventually rely on a mixture of inputs: it'll recognize voice commands, while also taking cues from the right sidebar. There's a touch-sensitive pad on there that'll understand gestures.
- It's entirely probable that Glass will also be able to be controlled via one's smartphone, but physical inputs will be the preferred ones.
- Glass has an accelerometer and a gyroscope, enabling wearers to tell Glass what to do by nodding, shaking one's head, etc. (For what it's worth, we've seen similar demoed by NTT DoCoMo.)
- The internal battery sits just behind the ear on the right side; the capacity and longevity weren't confirmed, though.
- Glass will be able to record locally, but the idea is to have 'most everything' streamed live to the web; it's the "live, right now!" nature of Glass that Google intends to push as one of its differentiating factors.
- In an area where wireless data isn't available (like a remote National Park or a hospital room that forbids phone usage), storing video locally would be possible for uploading later.
Out of all the things announced at Google I/O, this definitely seems to be the most revolutionary.
