Rachel Roumeliotis, a senior editor at O'Reilly Media, also started using the computerized eyewear this week and has been trying out the technology at the conference.
She said she feels comfortable with the system. She has asked Glass for directions to places in San Francisco, and has also used it to retrieve messages and take videos in her hotel.
She acknowledged that she has gotten some strange looks from people around the city, but that hasn't affected her experience.
"I can tell people are looking at me, but it doesn't bother me," she said.
Glass is designed to take photos and video, send and receive email, and even post comments and pictures on social media sites. The glasses are set up to be controlled by voice, gesture and touch.
At this week's developers conference, Google focused on trying to foster the growth and development of the Glass app ecosystem, noting that Facebook, Twitter, CNN, the New York Times and Elle magazine all have created software that it calls "Glassware."
Some members of the U.S. Congress are concerned about Google Glass and privacy. On the second day of Google I/O, the bipartisan privacy caucus sent a letter to Google asking questions about the kind of data stored in Glass.
