Google has created a page for the etiquette that revolves around Google Glass usage. The final suggestion in a recommended code of conduct posted online for software developers said that the user should not be creepy or rude.
Google said don’t “Be creepy or rude (aka, a ?Glasshole?). Respect others and if they have questions about Glass don?t get snappy. Be polite and explain what Glass does and remember, a quick demo can go a long way. In places where cell phone cameras aren?t allowed, the same rules will apply to Glass. If you?re asked to turn your phone off, turn Glass off as well. Breaking the rules or being rude will not get businesses excited about Glass and will ruin it for other Explorers.”
Google also asked Glass wearers to be polite and offer demonstrations to win over people that are wary about the technology. Google said that if users are asked to turn their phones off, turn off Glass as well.
The “do” list includes suggestions like Explore the world around you, take advantage of the Glass voice commands, ask for permission, use screen lock, and be an active/vocal member of the Glass Explorer Community.
