In some ways, Google Glass sounds like a web marketer’s dream since it can conceivably project advertisements directly onto users’ eyeballs. But thankfully for all involved, Google is having none of that. Google this week released a new Glass development guidelines video that helpfully instructs developers to not “get in the way” with their applications. In the video, Google Senior Developer Advocate Timothy Jordan explains to Glass developers that “the user’s life comes first” and that “users want Glass there when they need it, but out of the way when they don’t.” As CNET notes, Google is also specifically telling developers that they may not “serve or include any advertisements” in their apps, so it seems that Glass users won’t get bombarded with ads for miracle weight-loss drugs while they’re crossing the street. A full video of Google’s Glass guidelines is posted below.
