The most important parts of Intel’s new Vaunt smart glasses are the pieces that were left out.
There is no camera to creep people
out, no button to push, no gesture area to swipe, no glowing LCD screen,
no weird arm floating in front of the lens, no speaker, and no
microphone (for now).
From the outside, the Vaunt glasses
look just like eyeglasses. When you’re wearing them, you see a stream of
information on what looks like a screen — but it’s actually being
projected onto your retina.
The prototypes I wore in December also felt
virtually indistinguishable from regular glasses. They come in several
styles, work with prescriptions, and can be worn comfortably all day.
Apart from a tiny red glimmer that’s occasionally visible on the right
lens, people around you might not even knowyou’re wearing smart glasses.
Like Google Glass did five years ago, Vaunt will launch
an “early access program” for developers later this year. But Intel’s
goals are different than Google’s. Instead of trying to convince us we could change our lives for a head-worn display, Intel is trying to change the head-worn display to fit our lives.
Google Glass, and the Glassholes who came with it, gave
head-worn displays a bad reputation. HoloLens is aiming for a full,
high-end AR experience that literally puts a Windows PC on your head.
Magic Leap puts an entire computer on your hip, plus its headset is a
set of goggles that look like they belong in a Vin Diesel movie.
We live in a world where our watches have LTE and our
phones can turn our faces into bouncing cartoon characters in real time.
You’d expect a successful pair of smart glasses to provide similar
wonders. Every gadget these days has more, more, more.
With Vaunt, Intel is betting on less.
Putting the “wear” in wearable
Take the
stickers and part numbers off the Vaunt prototypes I tried this past
December, and they would just look like slightly chunky, plastic-framed
glasses. With a little more polish, I could see myself wearing them all
the time, even if they didn’t have a display. Though I only saw two
versions in Intel’s New Devices Group (NDG) San Francisco offices, Intel
envisions having many different styles available when the product
formally launches.
”When we look at what types of new devices are out there,
[we are] really excited about head-worn [products],” says Itai Vonshak,
head of products for NDG. “Head-worn products are hard because people
assign a lot of attributes to putting something on their head. It means
something about their personality.” That’s Vonshak’s politic way of
saying other smart glasses look terrible, so his goal was to create
something that has, as he puts it over and over again, “zero social
cost.”
”We wanted to make sure somebody puts this on and gets
value without any of the negative impact of technology on their head,”
he says. “Everything from the ground up is designed to make the
technology disappear.”
One of the Vaunt team’s primary design goals was to
create a pair of smart glasses you could wear all day. Vaunt’s codename
inside Intel was “Superlite” for a reason: they needed to weigh in under
50 grams. That’s still more than most eyeglasses by a noticeable
margin, but Google Glass added an extra 33 grams on top of whatever pair
you were wearing. Anything more and they’d be uncomfortable. The
electronics and batteries had to be placed so they didn’t put too much
weight on either your nose or your ears. They had to not just look like normal glasses, they had to feel like them.
That’s why all of the electronics in Vaunt sit inside two
little modules built into the stems of the eyeglasses. More
importantly, though, the electronics are located entirely up near the
face of the frames so that the rest of the stems, and even the frame
itself, can flex a little, just like any other regular pair of glasses.
Other smart glasses have batteries that are integrated into the entire
stem, “so those become very rigid and do not deform to adjust to your
head size,” says Mark Eastwood, NDG’s industrial design director. “It’s
very important when you look at eyewear that it deforms along its entire
length to fit your head.”
Tech at a glance
Okay, but
what does carefully cutting away extra technology and features so you
can have normal-looking glasses actually leave you with?
At its core, Vaunt is simply a system for displaying a
small heads-up style display in your peripheral vision. It can show you
simple messages like directions or notifications. It works over
Bluetooth with either an Android phone or an iPhone much in the same way
your smartwatch does, taking commands from an app that runs in the
background to control it.
One might say that this amounts to little more than a Pebble smartwatch on your face, especially because Vonshak designed Pebble’s excellent timeline interface before the company was acquired and shut down. But Intel has grand plans for the Vaunt’s tiny display.
Before we get into all that, let’s just lay down the
hardware basics. On the right stem of the glasses sits a suite of
electronics designed to power a very low-powered laser (technically a VCSEL).
That laser shines a red, monochrome image somewhere in the neighborhood
of 400 x 150 pixels onto a holographic reflector on the glasses’ right
lens. The image is then reflected into the back of your eyeball,
directly onto the retina. The left stem also houses electronics, so the
glasses are equally weighted on both sides.
So, yeah: lasers in your eye. Don’t worry, though, says
Eastwood. “It is a class one laser. It’s such low power that we don’t
[need it certified],” he says, “and in the case of [Vaunt], it is so
low-power that it’s at the very bottom end of a class one laser.”
The hardware here is all custom, all the way down to the
silicon that powers Vaunt — which is Intel-designed, of course. “We had
to integrate very, very power-efficient light sources, MEMS devices for
actually painting an image,” says Jerry Bautista, the lead for the team
building wearable devices at Intel’s NDG. “We use a holographic grading
embedded into the lens to reflect the correct wavelengths back to your
eye. The image is called retinal projection, so the image is actually
‘painted’ into the back of your retina.”
Because it’s directly shining on the back of your retina,
the image it creates is always in focus. It also means that the display
works equally well on prescription glasses as it does on
non-prescription lenses.
In addition to the VCSEL and all the associated chips
needed to power it, the Vaunt includes Bluetooth to communicate with
your phone. It also has an app processor (more on apps in a bit) and
some other sensors. Notably, it includes an accelerometer and a compass
so it can detect some basic head gestures and know what direction you’re
looking. The prototypes I used didn’t have a microphone, but future
models may have one so it can be used with an intelligent assistant like
Alexa.
Looking at Vaunt
In order to
properly use the system, Vaunt needs to be tailored to your face. That
involved a pretty quick and simple procedure: measuring my pupillary
distance. It’s a standard process that anybody who has eyeglasses will
be familiar with, and it’s essential for the display to appear in the
right spot in your field of vision. Once that was measured, a software
engineer programmed my measurements into a pair of prototype glasses,
and I put them on.
Using a Vaunt display is unlike anything else I’ve tried.
It projects a rectangle of red text and icons down in the lower right
of your visual field. But when I wasn’t glancing down in that direction,
the display wasn’t there. My first thought was that the frames were
misaligned.
Turns out: that’s a feature, not a bug. The Vaunt display
is meant to be nonintrusive. It’s there when you want it, and
completely gone when you don’t. Without a speaker or vibrate mode to
notify you, I couldn’t help but wonder if that would mean a bunch of
missed information.
Not so, according to Intel’s engineers. Your eyes are
very rarely just sitting still. They roam around and see things in their
peripheral vision all the time, your brain just doesn’t bother to
process and include all that information in your focus. But should there
be new information over there, you’d be likely to notice it.
The unit I saw was simply running through a demo loop of
potential notifications and information you might see: walking
directions, an incoming call notification. There aren’t any beeps or
vibrations when the display switches or a notification comes in, but you
do notice when it happens because the movement is noticeable in your
peripheral vision. Sort of like the T. rex in Jurrasic Park, it’s easy to ignore stuff when it’s still, but your eye keys into movement.
”We didn’t want the notification to appear directly in
your line of sight,” says Eastwood. “We have it about 15 degrees below
your relaxed line of sight. … An LED display that’s always in your
peripheral vision is too invasive. … this little flickering light. The
beauty of this system is that if you choose not to look at it, it
disappears. It is truly gone.”
The display should work both indoors and outside, but I
wasn’t able it test it in sunlight. Importantly, it should also last a
full day. Vonshak tells me they’re targeting at least 18 hours of
battery life. (Of course, when the battery runs out, they’ll still work
as, you know, regular glasses.) You should only have to plug them in at
night and not have to charge them up during the day.
It was fascinating how quickly I got used to having that
little display down there — even though it was just running through a
loop of pre-canned content. It became natural within less than an hour
to glance over at it to make it appear, or ignore it and focus on the
person I was speaking with.
That other person, by the way, would have to be paying
fairly close attention to have any idea whether I was looking at the
display or not. In fact, beyond a faint red shimmer on the lens itself
at very specific angles, nobody could even tell there was a display
there at all.
When you look at your phone or even your smartwatch in a
conversation, it’s a clear social indicator that your mind is somewhere
else. What will that conversation be like if the person you’re speaking
to has no way of knowing that you’re checking your latest Instagram
comment?
”So I’m talking to you right now and you feel like you
mean so much,” says Ronen Soffer, general manager for software products
at NDG, “but I’m actually playing a trivia game right now.” (He wasn’t
actually doing that, to be clear.) But after a day of playing around
with the Vaunt prototypes, I completely believe that sort of thing is
not just possible soon, but probably inevitable. Intel is thinking about
those implications, too. Soffer wryly jokes: “You can ignore people
more efficiently that way.”
Eyes on the platform
Of course,
really interesting new display hardware isn’t much without software, and
Intel isn’t ready to share too many details about software yet.
But NDG’s executives are happy to talk about the obvious
stuff: it will offload most of the work to your phone, just like a
smartwatch or even a Fitbit does. It will support some apps, it will
work with both iPhones and Android phones, and there will be some
integration with voice assistants at some point.
Vonshak was also especially clear about another point:
the goal is to do more than just blast notifications into your eyeball.
Instead, Intel aims to offer ambient, contextual information when you
need it. But since they couldn’t get into specifics just yet, all of the
examples were very hypothetical. “You’re in the kitchen, you’re
cooking. You can just go ‘Alexa, I need that recipe for cookies,’ and
bam, it appears in your glasses,” Vonshak says.
How will you actually interact with Vaunt? That’s also a
little unclear. Sometimes the hypotheticals involved voice. Other times
it seemed like very subtle head gestures — tracked by the accelerometer —
would be key. And in other ways, it seemed like you’re not supposed to
interact with it at all, but instead, just trust the AI to show you what
you need to know in the moment. One example I heard was getting
relevant information about the person who’s calling you (a birthday or a
reminder) while you’re on the phone with them.
Whatever the final interaction model will be, it will be
subtle and you shouldn’t expect to be doing a lot of pressing and
swiping and tapping. “We really believe that it can’t have any social
cost,” Vonshak insists again. “So if it’s weird, if you look geeky, if
you’re tapping and fiddling — then we’ve lost.”
One notable possibility: since Vaunt just uses Bluetooth
and Bluetooth Low Energy, there’s no technical reason you couldn’t
create a dead simple remote controller for it, say, on your smartwatch —
or maybe even on your clothing. I can’t help but note that one of the
places where Levi’s and Google developed Project Jacquard is literally right next door to NDG’s offices.
Focus on the future
News of the Vaunt first broke last week with Bloomberg’s scoop that said, “Intel plans to sell a majority stake in its augmented reality business.” Intel wouldn’t comment on Bloomberg’s
story to me, but I think the key line from the story is: “Intel intends
to attract investors who can contribute to the business with strong
sales channels, industry or design expertise, rather than financial
backers.”
That line jibes with what sources tell me — that Intel
isn’t so much looking to sell off NDG whole cloth, but instead find a
partner to help bring this thing to retail. It also jibes with what
Bautista told me back in December. “It is very unlikely that Intel will
take it to market because we typically don’t do that. Our core business
[is] we work the partners, we work with others to do that,” Bautista
says. “With these glasses, we’re working with key ecosystem hardware
providers — whether they’re frames or lenses and things like that.
Because we believe there’s a whole channel to people who wear glasses
that’s already there.”
Intel has a reputation for showing off ideas that never
turn into real products. It comes up with a cool concept, proves out the
technology, then hopes to convince others to take that idea and turn it
into a real product. CEO Brian Krzanich comes on a CES stage, talks
about a charging bowl (or hey, smart eyeglasses!), and then we wait to see if they’ll come to market. Often (maybe even usually), they don’t.
I think the intention with Vaunt is a little different from Intel’s usual playbook. For one thing, Bloomberg’s
report confirms that Intel is looking for partners with “strong sales
channels … rather than financial backers.” For another, Bautista and I
spoke a bit about how the sales channels for eyeglasses work now back in
December.
”There’s something on the order of 2.5 billion people
that require corrective lenses,” he says. “They get their glasses from
somewhere. Sixty percent of them come from eye care providers. … We
would say these glasses belong in those kinds of channels. People are
going to buy them like they buy their glasses today.”
It makes sense to sell eyeglasses in eyeglasses stores.
Not just because that’s a pre-existing sales channel, but also because
you’ll need to have Vaunt glasses adjusted to your pupillary distance.
Intel, despite its close relationship with Oakley, certainly doesn’t
have direct experience in those channels.
I don’t know if there’s a done-deal partnership to take
these things to market. I certainly don’t know if Intel has a plan for
either challenging or partnering with Luxottica, which has a massive and powerful monopoly over eyeglasses of all kinds in many regions of the world.
Sources say the most likely scenario is a spun-out startup company will
take Vaunt to market, backed by both Intel and whomever it partners
with.
Whoever does eventually try to sell Vaunt to real
consumers is going to face another challenge at least as powerful as the
Luxottica monopoly: ecosystems. In his time at Pebble, Vonshak himself
saw what happens to a wearable device that doesn’t have the deep OS
access it needs to truly work well. (Reminder: it gets sold off for parts.)
Since it’s not made by Apple or Google, Vaunt is going to need to find a
way to succeed where other third-party wearables could not.
That’s on top of convincing people that it’s normal to wear smart glasses and
that Vaunt provides enough value to justify whatever its price will be.
Unlike Magic Leap or HoloLens, Vaunt looks and feels normal. But it
also does way less than those devices. “Less is more” is a
wonderful theory. We won’t be able to see if it’s also a great business
model for some time.
Until then, what I can tell you is that I found the experience of trying Vaunt to be much more compelling than the overly techy cyborg AR glasses I tried at CES last month. Wearable devices need to fit into our lives before they can change them.
Vaunt is the first pair of smart eyeglasses I’ve tried
that doesn’t look ridiculous. They’ve proven to me that it’s possible to
make a kind of AR device that I’d actually want to wear every day. Now
we just need to see what Intel is going to actually do with all that
possibility.
