Smart Glasses | featured news

In order to write emails or text messages with Google Glass, you dictate words. The device is pleasantly reliable at transcribing things you say ... unless you happen to have a foul mouth.

Several companies produce sports eyewear that provides data, including speed and altitude, heart rate and time per mile, but critics say the devices create a distraction that could be dangerous.

In February, Google ran a contest for Glass offering "winners" the opportunity to be "Glass Explorers," i.e. the guinea pigs who will test out Glass in the wild. Downside: Explorers have to pay $1,500 for the product and for the privilege of being called "Glassholes." Upside: They get to test out a brand new product before anyone else. One 26-year-old Explorer came up with an even better upside: he planned to auction off his pair of Glass on eBay to pay down his student loans.

Developers making apps for Google's smart glasses have been told they will not be able to display advertising - nor charge for their product... For developers, that controversy could begin with wondering how exactly they will be able to make money from the device.
