Computer glasses have arrived, or are about to. Google has released some advance information about its Project Glass, which essentially embeds smartphone-like capabilities, including a video display, into eyeglasses. A video put out by the company suggests we’ll be able to walk down the street—and, we can extrapolate, distractedly walk right into the street, or drive down the street—while watching and listening to video chats, catching up on social networks (including Google+, of course), and getting turn-by-turn directions (though you’ll be on your own in avoiding people, lampposts and buses, unless there’s a radar-equipped version in the works).
Toshiba developed a six-pound surround-sight bubble helmet. It didn’t take off.
The reviews have mostly been cautiously enthusiastic. But they seem to be glossing over what an astounding leap this is for technophiles. I don’t mean in the sense that this is an amazing new technology. I mean I’m surprised that we seem to be seriously discussing wearing computer glasses as if it weren’t the dorkiest thing in the world—a style and coolness and common-sense violation of galactic magnitude. Video glasses are the postmodern version of the propeller beanie cap. These things have been around for 30 years. You could buy them at Brookstone, or via in-flight shopping catalogs. As far as I could tell, pretty much no one was interested in plunking these things down on their nose. What happened?
More interesting, the apparent sudden willingness to consider wearing computers on our faces may be part of a larger trend. Consider computer tablets, 3D movies, and video phone calls—other consumer technologies that have been long talked about, long offered in various forms, and long soundly rejected—only to relatively recently and suddenly gain mass acceptance.
The obvious explanation for the current triumph of technologies that never seemed to catch on is that the technologies have simply improved enough, and dropped in price enough, to make them sufficiently appealing or useful to a large percentage of the population. But I don’t think that’s nearly a full-enough explanation. Yes, the iPad offers a number of major improvements over Microsoft Tablet PC products circa 2000—but not so much that it could account for the complete shunning of the latter and the total adoration of the former. Likewise, the polarized-glasses-based 3D movie experience of the 1990s, as seen in IMAX and Disney park theaters at the time, really were fairly comparable to what you see in state-of-the-art theaters today.
I think three things are going on:
