Google has started public testing of augmented reality glasses known as "Project Glass."
The internet giant posted an introductory video to Google+ that showcases many of the headset's functions. Google wants the tests to "start a conversation" that will help it to improve the product.
Project Glass features a near-transparent video screen that transmits information in front of the users' right eye.
The video suggests that the user will be able to receive information - both contextually and on-demand - about their location, the weather conditions, and reminders from their schedule, presumably through integration with Google's other products, like Google+, Google Maps, Gmail and others.
Specific examples featured in the video include instant alerts for incoming mails and texts, the ability to dictate responses (and voice control in general), and a function that projects arrows on to the real world to help the user reach a destination.
Google hasn't released any information regarding pricing or release date.
