The only thing surprising about this gentleman in Shanghai, who seems to be using his face computer primarily for taking covert pictures of women he encounters on the subway, is that it took so long for someone to start doing it.
Update: the Glass user has deleted his tweets of unwitting women on the subway.
Google's vision of the future sure is cool.
Remember: this isn't an abnormal use of Google Glass, or some glitchy manipulation—the technology is designed to facilitate effortless face-based photography, be it on the train, or anywhere else in the world. The only thing stopping people from acting like voyerustic creeps with this toy is Google's vague request, and the honor system—just imagine when these things don't cost $1,500, and anyone can buy them.
