For the blind, smart glasses offer a clear path ahead

 |  Enviar respuesta id="article-body" class="row" section="article-body"> This is part of our Road Trip 2017 summer series "The Smartest Stuff," about how innovators are thinking up new ways to make you — and the world around you — smarter. 

Tiny drops of rain hit my face as I run through the sleepy residential neighborhood of Littleton, Massachusetts, about an hour's drive north of Boston. There's a slight incline to the pavement as it curves to the right. It's only been about five minutes, but I'm already tired and wet as I jog down the middle of a quiet street lined with Cape Cod-style houses on a gray and soggy afternoon in May.

I've never been to Littleton before and I have no idea where I'm going. Erich Manser, an IBM researcher who competes in marathons and Ironman competitions for the fun of it, runs beside me. He's wearing an orange hoodie with a fluorescent yellow bib that says "BLIND" in black bold lettering. I can't help thinking that this is really a case of the blind leading the blind.

At 6-feet-2, he towers over my 5-feet-7-inches. His long, easy stride highlights the fact that I'm not a runner (I hate running) and showcases how much time I spend binge-watching shows on Netflix.

Erich Manser shows me around his neighborhood of Littleton, Massachusetts, where he trained for the Boston Marathon with his Google Glass and a remote guide from Aira.

Nicholas Henry/CNET Manser, 44, isn't here just to give me a tour of his hometown. He's showing me how he runs and competes -- navigating the streets and guiding me around parked cars and the occasional motorist -- even with a degenerative eye condition that's left him legally blind in both eyes.

He's wearing Google Glass, the augmented reality glasses that gave their owners a figurative black eye (and earned them the nickname "Glassholes"). Manser's eyewear, though, was supplied by Aira, a San Diego startup that connects Google's smart spectacles to an online human guide who sees what he sees and directs his steps as needed. Manser learned about the technology a year ago, when he met CEO Suman Kanuganti at an accessibility conference.

I traveled here from New York to get a better sense of just how this system improves Manser's life. As our hoodies grow damp -- mine from sweat, his from drizzle -- I joke that I run a 10-minute mile, but just for that single mile.

Now playing: Watch this: Even the blind can see there's life left in smart glasses 4:42 "This is a lot different at 5 a.m.," he says of his usual training regimen. "It's quieter then."

The traffic is nothing like what he encountered on April 17, though, when he ran 26 miles amid the chaotic, jostling throng of more than 30,000 people competing in the Boston Marathon. Manser wore Glass then too, while an online Aira agent named Jessica Jakeway monitored his progress from her office two states away and made sure he had a clear path.

Every year, visually impaired people run in the Boston Marathon -- 54 ran in April. They typically prefer two physical guides to flank them because of how crowded the race can be. This year marked the first time a blind person attempted, and finished, a race with a remote guide.

Comeback trail
Manser's favorite pastime provides one of the more intriguing examples of a potential second chance for Google Glass in particular and smart glasses in general.

Google's $1,500 eyewear grabbed headlines and readers' imaginations when four skydivers jumped out of a zeppelin while wearing Glass for a 2012 demo that introduced the device to the world. With it, you could video chat with friends, view Google Maps for directions or quickly snap a photo. But that initial enthusiasm turned into hostility over privacy concerns. Bars, restaurants and the Motion Picture Association of America banned Google's fancy glasses from their venues.

Google suspended the project in 2015 and promised a new, less obtrusive model. On Tuesday, the company unveiled an updated version of Glass designed specifically for business use and featuring improved battery life, a crisper camera and a faster processor. Glass Enterprise Edition is available through a group of partner companies, including one that uses the eyewear to display patient records for physicians and another that trains employees in the food preparation industry. Aira is also a partner. 

Google declined to participate in this story.

Beyond Google, companies like Aira, Osterhout Design Group and Vuzix are hoping that people may finally warm to smart glasses as they introduce new designs and figure out different ways to use the tech. Surgeons are wearing ODG's glasses when performing a discectomy to relieve pressure from a herniated disk, for instance, with real-time X-ray feeds showing up on the heads-up display. The US military is now outfitting some soldiers with AR glasses that show the local terrain overlaid with a map. Factory workers may soon wear specs that display digital instructions for assembling a product. And smart glasses are remotely connecting experts with maintenance workers to repair complex equipment in the field. It's why research firm Forrester predicts 14 million US workers will don smart glasses by 2025.

New applications are transforming smart eyewear into useful tools for doctors, soldiers, remote workers and the visually impaired.

Nicholas Henry/CNET "There's absolutely zero question that head-worn computing cannot be stopped," Ralph Osterhout, CEO of Osterhout Design Group, told me in an April interview.

A future where you head out the door with phone, keys and smart glasses isn't that far-fetched. That's because the world you see through the new crop of glasses is different from what we expected from Google Glass, thanks in large part to Apple, Microsoft and Facebook pouring billions of dollars into augmented reality. Unlike virtual reality, which immerses you in a fictional universe, AR technology inserts digital images over the ones you're seeing in the real world. Think Yelp reviews that pop up when you point your phone's camera at a local restaurant, or spotting "pocket monsters" in the park when you're playing Pokemon Go.

It's not a stretch to imagine that smart specs may help you "see" these digital AR layers as you walk around town or shop at the mall. Thanks to Snap's $130 colorful plastic Spectacles, people aren't even that wigged out by seeing cameras embedded into eyewear.

Now, if we can just get past that uncool factor.

Remote guide
Manser, who has retinitis pigmentosa, compares his vision to looking through a straw that's had one end covered over with wax paper. Doctors diagnosed his condition when he was 5. He's been gradually losing his sight ever since.

"You get used to seeing things a certain way, and suddenly it changes on you," he tells me that May afternoon as we sit on his living room couch, the sound of emergency sirens occasionally blaring on his street.

The view from Aira agent Jessica Jakeway's dashboard as Manser ran the Boston Marathon.

Aira A swimmer in college, Manser's activity slowed significantly as his vision worsened after graduation -- at one point, he gained 70 pounds. But he says his background in sports and the support of fellow athletes helped him find his way back to running marathons and competing in Ironman contests.

He's been using the Aira mobile app for 10 months and Glass since January. (Aira previously was just the app that relied on your phone's camera to give its remote guides a video feed.)

When Manser dials in via the app, an Aira agent gets the feed from the camera mounted in Glass. The agent also sees a second screen with the customer's location on Google Maps or Street View, along with relevant local data like bus schedules or restaurant reviews.

At first, Manser used Aira for help with things like negotiating a crowded train station, cooking and basic runs.

Then in February, he and Kanuganti talked about using it during the Boston Marathon as an extreme test of the system. "We knew it was a stretch, but we wanted to push it," Kanuganti says. The race was just two months away.

When you're looking through a straw, there are situations where it feels like people are coming out of nowhere. Marathon runner Erich Manser Jakeway -- an agent living in Columbus, Ohio, who also runs marathons -- became his training partner. They'd joke about running techniques even as she'd point out potholes and call out patches of melted snow during his training runs.

But when Manser finally reached the marathon's starting line, it didn't go as he'd envisioned: Google Glass was having trouble connecting to the Aira app.

"I remember standing in the starting corral and [the app] kept cycling on my phone, [trying to] find my glasses," Manser tells me.

Fortunately, Manser -- an accessibility researcher at IBM -- had arranged for one of his colleagues to run with him as a second guide, a rubber tether keeping the two together. That physical guide helped him get through the crush of bodies in the first four miles of the race. Eventually, they pulled off to the side and established a connection between Glass, iPhone and Bluetooth headphones, all tied to a puck-size AT&T mobile hotspot Manser carried that linked back to Aira.

That's when Jakeway jumped in -- Glass showing her everything that lay in Manser's path.

"Runner left," she'd call out. "Runners right."
