Google Glass update brings a browser to the device as well as new features
The update will now allow you to send a message or call any of your Google+ contacts by clicking on "Send a message to..." from the main menu. Scroll through your contacts' photos and tap on the appropriate picture to send a message or make that phone call. The update also allows Glass users to delve deeper into a search. While searching on Google Glass, you can learn more about what you are searching for by clicking on a "View Website" link to see a web page.
Navigating on the Google Glass browser requires you to let your fingers do the walking. To scroll on the browser, you slide your finger on the touchpad. You can zoom by taking two fingers and sliding forward and backward. With two fingers on the touchpad, move your head left and right to pan around the screen. And, while you are looking around, you can tap to select anything in the center of the screen.
Google says that Google Glass owners will see the update pushed out to them automatically in the next couple of days.
