When Astro Teller, head of Google's secretive Google X research lab, addressed a Vanity Fair gathering of the technorati in San Francisco last month, he said convincing people to wear a smart device on their face or any part of their body is a "tough" sell.
How tough? Companies need to make devices useful enough to compel you to attach them to your body, he said at the time.
But there's another catch: Wearables, from Glass to smartwatches, also need to be cheaper -- a lot cheaper -- before they go mainstream.
"Every time you drop the price by a factor of 2, you roughly get a 10 times pick up of the number of people who will seriously consider buying it," Teller said in an interview at Google's Mountain View, Calif., headquarters. That means "two more rounds of halving in price" for most wearables before they're an attractive buy.
For certain products, like $30 or $40 pedometers, a big price cut probably won't make much of a difference, he said. "But for a $200 watch, or Glass, or anything in between, I think it's sort of fair."
For Google Glass, which costs $1,500 today, cutting the price in half twice would mean a drop to $375 -- though the company said it couldn't comment on a price target or timeline for any cut. But Google, which generated almost $60 billion in sales and $13 billion in profit last year, could absorb the cost cut -- if it did want to make Glass a mainstream gadget rather than a novelty. Analysts who dismantled the eyewear and appraised the value of the individual parts pegged the total costs of Glass' components at up to $150. That means, right now, Glass seems to be selling for at least a 900 percent markup.
Glass was developed at Google X, which also is working on driverless cars, smart contact lenses and Wi-Fi-beaming balloons. It is one of the highest-profile products in the wearables market, a new class of devices making waves in the technology industry. What was once a dream of science-fiction writers -- a computer that's always there to respond whenever you want -- is becoming a reality. Market research firm IDC projects that from the end of this year to 2018, wearable shipments will increase nearly sixfold to 111.9 million units.

But it's not the "Star Trek"-type utopia we all imagined. Not yet.
Price is a definite barrier, and Google isn't the only company facing the "How much?" question. The Apple Watch, Apple's first wearable, works only with the iPhone and will be released early next year with a starting price of $350. Various versions of the watch, including the 18-carat rose and yellow gold editions, are expected to cost more, though Apple hasn't detailed pricing. Samsung and Sony also sell smartwatches with sticker prices in the hundreds of dollars. Meanwhile, a classy Timex watch still goes for less than $40.
Another concern for wearables is a cultural one. Glass has become a sign that Silicon Valley may be falling out of step with the rest of the world.
Since it was unveiled in 2012 in a live demonstration that included skydivers and stunt people repelling down a San Francisco building, Glass has been the subject of fascination, ridicule, debate and scorn. The derision was so great that Google in February created a set of etiquette guidelines for Glass users. (Sample: Don't "be creepy or rude, aka a 'Glasshole.'")
Technology enthusiasts, cultural critics and artists from Silicon Valley to Wall Street to Middle America continue to debate the merits of Glass. The central question: How will Glass fit into our society?
Glass' opponents have been vocal. The device has been banned from some bars and restaurants, and lawmakers in at least eight states have written bills to outlaw its use by drivers in cars. In October, the Motion Picture Association of America prohibited moviegoers from donning any wearable tech with recording functions, including Glass, in theaters. Glass also seems to be losing traction among developers, according to a Reuters report last week.
Glass supporters, meanwhile, see all of this as resistance to change. Teller argued that millions of people who carry smartphones already have cameras and microphones in their pockets when they are at bars or attending movies. Glass, he says, won't "move the needle" on the number of recording devices in the world anytime soon.
