An anonymous reader writes: One of the biggest worries about the rise of wearable computing is the ease with which random strangers will be able to record your actions without your knowing. Right now, it's pretty easy to tell if somebody's holding up their cellphone taking some video. But when everybody's wearing Google Glass, or something similar, it will become harder to tell, which has led to preemptive bans on Glass in certain places. Now, Google has published a list of Do's and Dont's to tell Glass users how they should behave politely in public. Do: ask for permission before recording people. Don't: ignore the world around you, expect that people won't notice, or wear it during a cage fight. Also, most importantly, don't 'be creepy or rude.' Google says, ' Standing alone in the corner of a room staring at people while recording them through Glass is not going to win you any friends.'
