In order to alleviate privacy concerns, Google has created a frequently asked questions (FAQ) section for Google Glass, a wearable computing smart-glasses product. The questions around Google Glass privacy concerns revolves around information collection, recording, tracking, and facial recognition.
When asked what Google Glass does to inform non-Glass users if a picture or video is taken, it says that the device’s screen is illuminated whenever it is being used. Glass also requires the user to speak a command like “OK Glass, take a picture” or “OK Glass, record a video.”
The Google Glass FAQ also explains that Glass does not record video or take pictures all the time. The default video recording on Glass is set to 10 seconds. The battery life does not allow Google Glass to record over 45 minutes of straight recording.
