One of the most practical limitations to augmented reality is battery life. Glass is limited-enough as it is, simply handling text messages, phone calls, and the occasional photo. It dies on me all the time. I can't imagine it recording (and processing) video for AR for very long between charges. Half an hour would surprise me.

It doesn't seem like that would be too difficult to offload most of that processing to a smartphone. I think they made a mistake not making Glass an accessory for Android rather than it's own device. It also wouldn't be impossible to put a heavier battery and wire connected to the Glass device in your pocket for much longer battery life in exchange for the minor inconvenience of having a wire tucked in your shirt.

  I'd assume the video recording is more battery-intensive than the processing. Also, if you offload the processing to the smartphone, then it'll be necessary for Glass to be connected to your phone, which means wifi and/or bluetooth, which only drains the battery more.

    The new Bluetooth Low Energy could help a bit with that a bit.

      From my reading, Bluetooth LE isn't so "low energy" when you send lots of data, http://en.wikipedia.org/wiki/Bluetooth_low_energy#Radio_interface http://en.wikipedia.org/wiki/Bluetooth_low_energy#Radio_inte.... In the end, you still need to use a bit of power.

    It might be a challenge but there's no need to completely dismiss the possibility. Here is a $5 keychain that can record for 1.5 hours. http://www.amazon.com/808-Car-Chain-Camera-Recorder/dp/B00849KQD0 http://www.amazon.com/808-Car-Chain-Camera-Recorder/dp/B0084... I'm sure Google and the countless engineers and scientists working on advanced battery technology could make something work for a reasonably long amount of time. And there's no reason that you couldn't put a laptop size battery in a bookbag with a cord to the glasses and have an all day charge. Either 3 hrs without the optional extra battery or 24 hrs with the 3 lbs bookbag battery, that doesn't sound so bad to me, at least until we create better batteries.
