Send messages to your contacts hands-free by saying "OK glass, send a message to..." Speak the name of your contact or select the name from the list. Speak the content of your message.
Your transcribed message will appear on the display. As soon as you're done speaking, you have a couple seconds to cancel before it's off to your friend's inbox. To cancel, swipe down on the touchpad.
Messages are sent by email unless you have an Android phone or tablet and download the MyGlass app. Glass will then send SMS messages by default to contacts with a phone number. Contacts can be added or edited either from the MyGlass site or the MyGlass app.
