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.
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.
it is those features that make me realize this is gonna be something amazing once they start.
