Users will also be able to speak to Glass to instruct it to take a photograph, get travel directions on a heads-up display in front of their eyes, or speak to Glass to send a message to someone else.
The device will be able to share what users are seeing and to answer their questions through a wireless Internet connection, according to Google. It will also allow users to ask for translations in other languages, such as how to say a word in Chinese.
Glass also will be able to give users information without having to be asked, such as gate and departure information on flights as they head to an airport.
Several photos of Glass being used in various situations are also featured, as well as images of the five colors from which participants can select for their devices. Early Glass versions will come in charcoal, tangerine, shale, cotton or sky colors.
Google recently held two "hackathon" events in New York City and San Francisco as part of its "Glass Foundry" program to collect developer input for the devices with an emphasis on developing the Google Mirror API. Attendees were given access to a Glass device for use and testing.
The company will also hold a Building New Experiences with Glass session on March 11 at the South by Southwest (SXSW) conference to further the project's development.
Earlier this month, it was unveiled that Google Glass will apparently transmit sound to its users via vibrations through human bones rather than relying on traditional speakers.
Google filed a U.S. patent application Jan. 24 for its "wearable computing device with indirect bone-conduction speaker," which calls for a sound transmission system that transmits sounds to users' bones without the use of typical earbuds or speakers. Such bone-conduction systems already are on the market in some products and headsets, but until now there was no mention of this in earlier Google papers filed about Glass.
The basic components of Glass feature an Android-powered display, a tiny Webcam, a GPS locator and an Internet connection node built into one side of a pair of glasses. The glasses are lightweight and may or may not have lenses.
An actual Google Glass device was spotted in public Jan. 21 being used by Google co-founder Sergey Brin on a New York subway train. The sighting was posted by a device hardware prototyper and hardware hacker who recognized the device and spoke briefly to Brin about the project.
