Google has posted information about Project Glass. The photos and video show a stylish, lightweight eyeworn see-through display operated via a speech interface, which allows you to do many of the things you already do with your iPhone, but without manual interaction. This announcement has been expected for some time and we mentioned it in an earlier post on HMDs titled Retro-Future. It will be increasingly difficult to justify the purchase of outrageously priced and bulky retro-HMDs when consumer products with superior form-factor and functionality come on to the market. Currently price estimates for the AR eyewear run from $200.00 to $600.00, but this is guessing. No doubt Google will make APIs easily available for the eyewear, so that R&D can be conducted by anyone with modest means and sufficient motivation. The video, available via YouTube, is probably mostly a mock-up and I’m wondering where the battery will be located.
