Kimberly Ann Graham says it's hard to imagine life without her Glass.
"I feel like I'm missing a sense when I forget it," she says. "Like the cell phone. We know we can and did live without them, but would we ever give them up completely? Not voluntarily!"
Graham, a driver for the car service Uber, says wearing Glass has given her the confidence to talk to anyone. "I have the inside edge on this tech and that makes me the expert in just about any conversation on the street. That safety net has allowed me to develop the confidence in all areas, something I lacked for all of my life prior to Glass."
One of Kathryn Jensen's favorite things to hear is: "Well, you don't see that everyday." For her, that makes Glass irresistible.
Kathryn says she mostly uses Glass to take pictures and videos during her daily 10 mile walks. Most recently, she's used Glass to help her learn French. She also used the device's translator app while was visiting Paris for the first time.
Julien Boubel is an adviser for museum tour guide company GuidiGO.
Last year, the company partnered with the de Young Museum in San Francisco to let visitors use its Glass app during an exhibit for the artist Keith Haring. How it works: When someone wearing Glass approaches a piece of art, audio and visual content automatically pop up to give the viewer more context about the piece.
Justin Chung is a San Francisco-based freelance illustrator known for his work on Star Wars and Marvel Comics trading cards.
One of the things he uses Glass for letting people see what he's drawing, while he is drawing it.
Chung considers the Explorer program a very important "social experiment." "Centuries from now, we'll look back on it," says Chung. "You're putting cyborgs out in public, and we were out there trying to learn the right social protocol."
