ck2• 14 years ago

Even the smallest smartphone chipsets still need big batteries, I suspect it's going to be a pocket device with a wire or bluetooth of some kind going to the glasses.

Still an amazingly aggressive technology product.

Lewisham2• 14 years ago

I hadn't considered the battery aspect. Having a wire would kill this in the consumer market. Bluetooth to a central pack... Maybe.

dandelany2• 14 years ago

Unless I've missed a big recent announcement, wireless energy transfer, even over a short distance like pocket-to-glasses, is a long way off from being feasible. My money is on a tiny battery built into the glasses themselves, and a screen/CPU optimized for using miniscule amounts of energy. The problem is that wireless data transfer still requires quite a bit of power, so they will either need to do lots of optimization to only transfer data when absolutely necessary (and turn the transceiver off the rest of the time), or come up with a system in which the glasses talk to a central device in your pocket using a low-energy data transfer scheme, and the central device talks to the network over WiFi/3G.

(On second thought, maybe that's what you meant by "bluetooth to a central pack")

james33• 14 years ago

Maybe it would integrate with the central device already in your pocket, your Android phone, over bluetooth.

iandanforth2• 14 years ago

I advocate for a necklace battery pack. It would also serve to hold your earbuds.

granitepail• 14 years ago

I definitely checked the date a few times, but this makes an awful lot of sense given Google's position. At this point it's really just hardware to bridge the accessibility gap.

gfodor• 14 years ago

My biggest concern is if this is executed poorly it could undermine future attempts to bring wearable computing to the mainstream. It still feels a bit early for this to work well. Google can pull off the technical challenges, surely, but the usability hurdles here are outside of their comfort zone.

dandelany2• 14 years ago

I don't really see this being an issue... First generation emerging technologies always have big problems, and early adopters know it. Think about pre-iPhone smartphones - they (largely) sucked, but that fact hasn't had any effect on the market for well-engineered smartphones today, as far as I can tell. If anything, Google releasing a product with major deficiencies that early adopters still find valuable will spur further development in the same space by competitors.

pyre2• 14 years ago

You could arguably say that early attempts anchored the industry (into a certain way of thinking about what a smartphone was and how it worked) until Apple came along to pull it out of that rut...

DanI-S• 14 years ago

The article makes it sound like this is more an 'opt in through purchase' experiment rather than a serious product launch - perhaps that is to mitigate this particular concern.

seancron• 14 years ago

I remembering reading somewhere that they might actually test this like they did with Chromebooks (Cr-48) and distribute them to people to get feedback.

mcrider• 14 years ago

Because this won't be valuable until there is serious data that they can statistically infer different things on (like how Google Translate and other services get better over time). It also sounds like (perhaps wishful thinking) that it would be an open experiment, i.e. with open software and APIs for third-person development.

cpeterso2• 14 years ago

I think the popularity of Jawbone Bluetooth headsets suggests even non-techies will happily adopt wearable computing devices.

chc• 14 years ago

Unless I'm misunderstanding what you mean, those are more like glorified headphones than computing devices.

hsuresh• 14 years ago

On the other hand, someone has to make a start. We might see more such products, even if it is only moderately successful.

SoftwareMaven• 14 years ago

I am horrible at remembering names. The day these things can do facial recognition againt my address book, Facebook, and LinkedIn profiles and pop up a little box with the person I'm looking at's name is the day I will never go without glasses again.

barefoot• 14 years ago

That would be amazing, and really useful at tech conferences.

One could imagine something like Klout running in the background and telling you who's important, who has similar interest to you, etc... The social implications are mind blowing.

xxbondsxx• 14 years ago

That's a big idea... Although I would feel a bit bad bringing the online social hierarchy / totem pole into the real world. We already care _too_ much about Klout and Karma scores, the last thing we need is twitter gods parting the seas at tech conferences.

cpeterso2• 14 years ago

Here is a TED 2009 demo of MIT's "Sixth Sense" wearable computer. It's like Minority Report but operates on any wall. It's features include visual overlays of social profiles for the person you're talking with. :)

Steko3• 14 years ago

Pro: Because it's Android we can hack an awesome DBZ power level widget into the HUD.

Con: The glasses hit you up to join G+ every 30 seconds.

"10-200ms with random jitter" don't we love Java :-p

prawn• 14 years ago

And require you to set up a new account if your other one is a Mail for Domains account.

pshc• 14 years ago

Not saying this is what they're selling, but: Real-time overlays are still impractical, right? My intuition is--without a really high speed camera and high fidelity environmental cues--the overlay will have a lag and high uncertainty wrt where you're actually looking... or has the state of the art moved on? Or are their labs advancing the state of the art?

Any idea how they're making the screen usable at that focal length? Don't VR headsets usually need optics much more bulky than sunglasses for comfortable viewing?

Anyway, even if it's smartphone-like functionality in a more convenient form factor, I'm looking forward to being an early adopter.

sanswork• 14 years ago

You can get away with smaller screens if you're just doing a HUD instead of a full immersive environment.

sbierwagen3• 14 years ago

The Nintendo 3DS does AR overlays with mostly tolerable lag, though I wouldn't want to be looking at the world through it: https://www.youtube.com/watch?v=YkbWZiZ01G0

Ralith• 14 years ago

It needs an easily pattern-matched reference point, though.

adgar• 14 years ago

I mean... depending on big the frames are... maybe the state of the art being advanced is designing really, really skinny and long high-end ARM chips down the arms.

Only about 20% serious.

joezydeco• 14 years ago

"Real-time overlays are still impractical, right?"

Word Lens seems to be doing it just fine on an iPhone:

http://www.youtube.com/watch?v=h2OfQdYrHRs

Seriously, foreign language translation would be a natural for a product like this.

johnyzee• 14 years ago

The current state of camera based AR is not compelling, primarily due to unimpressive displays (low resolution and small field of vision), but also because of lag as you mentioned. Most solutions are based on Kopin display components which are really screens for handycam viewfinders.

Vuzix is doing something really interesting with transparent displays using waveguide technology (http://www.engadget.com/2012/01/12/vuzix-augmented-reality-s...). This, to me, is the future of HUD glasses. A solution with a screen blocking one eye, as it seems Google is doing - I can't see that working out, unless they are sitting on some breakthrough display technology.

BadassFractal2• 14 years ago

Exciting news! Just yesterday I was watching John Carmack's interview from 2011's QuakeCon and at the end he mentioned that he was going to soon start playing with display glasses to see if anything interesting would come out of it (for id, I imagine).

Driverless car, now digital glasses. I'm positively impressed that Google keeps pushing the envelope in all these different fields.

"""A HMD without head tracking is counter-productive – the view feels like it swims opposite every tiny head motion."""

This guy knows his pixels. :-) Tweet was just this week, I believe. He's had a few others w.r.t. head tracking, FOV / display issues with fancy new displays. Definitely interesting to see his challenges.

BadassFractal2• 14 years ago

That's awesome, really exciting to know that he actually started experimenting with the tech.

berntb• 14 years ago

How is the reading experience? Can you get 80 chars into it?

I hope there isn't a good one hand keyboard interface (chording?) so you can write email/code while bicycling/driving/etc -- with my simultaneous capacity, it would be my death...

From the linked previous post about wearables:

alexgartrell2• 14 years ago

Man, you've been around here for two years longer than I have. You know that there's no value added by blatant sarcasm. If you're actually afraid that Google will use your captured images to serve you unwanted ads (and, btw, revolutionize computer vision in the process), then say exactly that. Crackin' wise about snackwells isn't getting anyone anywhere.

MattJ100• 14 years ago

That wasn't really sarcasm. It was exaggeration, perhaps. But even then, perhaps it wasn't even that (given enough time).

staringispolite4• 14 years ago

Is sarcasm always unwanted here? I actually chuckled at the beginning until it turned too serious toward the end.

There was a great TEDx talk on the (well-executed) use of humor, and satire in particular, to get points across when they would otherwise be disregarded, or to make bland points more viral: http://www.ted.com/talks/chris_bliss_comedy_is_translation.h...

I don't see a reason to discourage sarcasm out-of-hand, or any other form of humor. Based on the merits of the individual comment, sure.

magicalist• 14 years ago

Er, versus already carrying around a phone with built-in GPS and camera? Carrying around a networked computer is a new thing? That's why privacy policies exist (and why they should be monitored and enforced).

That is, if you're an internet company. To find out that AT&T is logging your location indefinitely (since 3.5 years ago), you need the FOIA:

Here are some high-quality sf books you can use to imagine the possibilities of this technology.

http://en.wikipedia.org/wiki/Rainbows_End

http://en.wikipedia.org/wiki/Halting_State

mindcrime• 14 years ago

Of those, I've only read Halting State, but it is a really cool novel (although written in something of an odd perspective). I'd definitely recommend it to anyone who hasn't read it yet, and who generally likes cyberpunk'ish fiction.

Are you referring to how awesome the AR seems to be in snow crash, or the horrible brain viruses they were vulnerable to.

schiffern• 14 years ago

Synthetic Serendipity is free online: http://spectrum.ieee.org/computing/networks/synthetic-serend...

It's a short story in the same universe as Rainbow's End, and deals extensively with wearable computers.

simmons• 14 years ago

Yes. _Rainbows End_ and _Halting State_ were the first things that went through my mind when I saw this headline. :) I personally find a lot of inspiration for my work in such stories.

Golden age trilogy is bar none the best hard sci-fi far future trans human sci-fi there is. Highly recommended.

gojomo2• 14 years ago

Season 1 episode 3 of BBC4's 'Black Mirror' anthology series, titled "The Entire History Of You", is also a great look at at the implications of in-eye, always-on recording/playback devices.

aGHz• 14 years ago

Absolutely loved that miniseries and recommended it to everyone I know. The second episode also deals with a high-tech future, while the first one explores a more social angle of our current connected world.

bwarp• 14 years ago

It's books like that (I've read all three) which bring the luddite in me out.

I'm all for computers helping us perform tasks but sometimes things go a little too far.

dan_yall• 14 years ago

I'd add Daniel Suarez's Daemon and FreedomTM to that list, at least if you're interested in this technology's ability to mobilize an army of nerd-assassins to remake society.

wavephorm• 14 years ago

Yeah so everything I look at is going to go through Google's servers, and be processed and display Google ads constantly no matter where I'm looking. Yeah right. Google is flat-out lunatic if they think consumers want this level of invasion into their lives. They're taking the Orwellian computing idea, big brother always on everywhere, to the absolute extreme here.

shalmanese2• 14 years ago

Have Google figured out a way to solve the accomodation/vergence problems inherent in screen based 3D displays (http://research.microsoft.com/apps/pubs/default.aspx?id=6402...)? Because if not, these things are going to suffer from the same dismal failure that every other 3D display product has over the last 30 years.

jfoutz4• 14 years ago

It's not clear they're going for a 3d experience. My guess is it's just a hud without eye tracking. A camera for labeling the world a'la virtual light would be cool, but still laggy. Does not matter. I would insert the picture of a kitten with the text "want" but this is not reddit.

shalmanese2• 14 years ago

It needs to be 3D to pitch text. Hold a piece of text 3 inches away from your eyeball and try reading it. Then imagine how painful it would be to have that there 8 hours a day.

iamgilesbowkett• 14 years ago

Upvoted for the 'Virtual Light' reference. Like basically everything else online, William Gibson described this years ago.

jfoutz4• 14 years ago

I can't imagine them not looking hideous, but i want them. i've wanted them for pretty much two decades now. I'm sure they will suck. I will happily give google a pile of money for the few weeks of usage i'm guaranteed to get out of them. It's just a bonus if they're actually useful.

orofino• 14 years ago

I've been waiting for this for a long time. I wear glasses currently and have always felt that some kind of overlay could provide tremendous value.

From simple reminders, augmenting my environment with meta data, or giving access to real time updates about almost anything the possibilities are almost endless.

Batteries are going to truly be the limiting factor IMO. Forget plastics, the future is batteries. I assume version 1 of the product will require some kind of external battery pack, I'd think it was certainly worth it if the tech is what it should be.

downx3• 14 years ago

I was thinking as a glasses wearer - that I'd be excluded from the product.

Have you tried to wear 3D glasses over your existing pair?

I wonder how lightweight they'll be, especially if you factor in batteries.

yew2• 14 years ago

If they're lightweight enough you could have the lenses replaced and just wear the digital pair. That's what I'm planning on looking into, once the technology matures a little.

mbeswetherick• 14 years ago

Google is pretty ballsy.

After their Safari tracking system fiasco they announce this: the ultimate form of tracking. It shouldn't come as a surprise that Google would make this considering the rest of their products.

I love Google and their products, but I feel this takes it over the line. At what point will Google be satisfied with the amount of information they're able to collect? Maybe the world will become some strange Utopia where products like these glasses are acceptable and Google made the right call, but Google should take a step back and realize they're making technology for humans, not robots.

If this trend continues I bet we'll see Google Children roaming our street. Ok, that's pretty hyperbolic but you get my point.

coopdog• 14 years ago

Opt out?

They're just giving you more choice, not less ala apple

sopooneo• 14 years ago

Is this article implying the glasses will work like a HUD, with the image displayed on a transparent surface that you can also see through? Or is it an opaque screen off to the side? Or it couldn't possibly be an opaque screen over your eyes that redisplays what you would have seen behind it?

tehdanish• 14 years ago

The article implies they are a completely separate Android device. Why not just interface with Android / iOS devices?

staringispolite4• 14 years ago

And Google Goggles is already taken. WHY?!

hesdeadjim• 14 years ago

All I have to say is: please, please, please let this actually happen and work even 50% as well as my imagination wants it to.

derrida2• 14 years ago

How do I opt out of all face recognition? I have a right that my personal life not be exploited for advertising by a large company.

staringispolite4• 14 years ago

I think Google is usually pretty forward about their privacy policies and letting you customize what data they store. (See those recent "this stuff is important" popups on virtually every Google property)

Here's hoping they thought of issues like: Guy wears his new "Google Goggles" to a racy late-night sales meeting, and Gmail serves how wife ads for divorce papers.

dredmorbius2• 14 years ago

There's always the paper bag solution.

Most scanners to date have been moderately vulnerable to blocking devices. Say, a backscatter laser of some sort. And if personal identifiers are based on you carrying a broadcast device (e.g.: an info-leaking phone), one simple solution is ... don't do that.

I suspect that both the technology and its countermeasures will first be utilized by government (and corporate) "security forces".

Hrm ... related query: is it possible to build a simple device which would short out RFID scanners? If it becomes trivial enough to destroy the readers, then ubiquitous, obnoxious uses might at least become more expensive.

derrida2• 14 years ago

I don't think you are getting rid of RFID, they are too cheap and low-tech to get rid of. I hear Aluminium foil does the trick.

SquareWheel• 14 years ago

Well hey, just create a Google Plus account and update your settings...

But really, the privacy implications are significant. I think Google knows this, and will take the necessary steps. At least, I sure hope so.

yew2• 14 years ago

I think the real issue is how to respond to my wearing a camera that records everything I do and, incidentally, everything that everyone around me does. Even if the data's never sent to a third party, there are still privacy concerns. They're just a lot harder to address, unless "ban lifelogging" strikes you as a reasonable response. (It doesn't me.)

moocow01• 14 years ago

In all honesty probably wear a pair of those glasses - If we are all wearing e-glasses, facial recognition may not be so plausible.

mattstreet2• 14 years ago

Makeup?

rkaplan• 14 years ago

Does anyone see this actually catching on in the next five years and becoming something more than a gimmick?

I'm as excited about the prospect of viewing the world through a HUD as the next guy, but I can't imagine these glasses looking sleek in the slightest, and they will likely be rather bulky.

But beyond ugliness, it seems to me that someone would rather pull out their smartphone than put on a pair of HUD glasses for any given use case for this product. Augmented reality is "cool" but I've never used an AR app more than two days after I downloaded it.

I think for it to catch on, this technology would have to be baked into glasses that are designed to be worn all the time, not just put on when needed. People aren't going to carry around AR glasses in their back pocket with their phones and wallets. So a place to start might be enhancing the glasses used by people with vision trouble, rather than creating a whole new glasses product.

city41• 14 years ago

I can think of two markets that this may do well in: motorcyclists and runners.

Motorcycle HUDs have existed for quite some time now, but more competition especially from someone as big as Google will inject some much needed innovation.

I can also see this being popular with running enthusiasts. During my races I wear a paper band around my wrist with my ideal times for each mile, and then have my GPS watch set to show instantaneous pace. A race involves constantly looking between watch, paper printout and your surroundings. If I had a HUD, I might even enjoy the race a bit :) (that was slightly sarcastic)

joshontheweb• 14 years ago

But can they look good? Those oakleys linked to are awful. If they look stupid then I doubt they will work... Until apple steps in and does it right, that is ;)

jobu• 14 years ago

If anyone hasn't read Daemon & FreedomTM by Daniel Suarez I highly suggest it. His use of tech like this in the novels was pretty well thought out. Can't wait until Google uses these to integrate a MMORPG with RL.

mrbill• 14 years ago

The first thing that came to mind is Manfred Macx in _Accelerando_, and how hopelessly lost he is without his AR goggles.

"... One Google employee said the glasses would tap into a number of Google software products that are currently available and in use today, but will display the information in an augmented reality view ..."

wonder how many Steve Mann patents they are using? ~ http://www.eecg.toronto.edu/~mann/

notatoad• 14 years ago

i find this very hard to believe. it seems obvious to me that smartphones and tablets have completely filled the niche invented by the HUD glasses of yesteryear's science fiction. they will never be popular, because they are too invasive. people like to be able to put the internet in their pocket and take it out again when they need it.

i wouldn't be surprised if google has a bunch of engineers working on the technology that could be used in HUD glasses, but i would be very, very surprised to see anything ever come to market. google will not enter the hardware market with such a risky product.

sebastianavina• 14 years ago

i thought the same of hands free cell phones... and I found people all day long with headphones, sometimes listening music, sometimes just in case the phione rings.

On a second thought. Some people already use glasses all day long. It would be great for most of them to have a little display with the current time, mail status, incoming calls, and along... At least, for me sounds nice.

jhickner• 14 years ago

They'll never be popular? I think the main impediment to wearable computing has been how socially awkward it is. If someone actually came up with a discrete, well-designed glasses-based computer, I think it would be immensely popular.

AR won't really come into it's own until such a platform exists. Holding a phone in front of your face is just too awkward.

- read any language

- never forget names

- navigational aids (obviously)

- identify any bird, plant, etc.

- a whole raft of products just geared around augmenting the museum experience

- look at a printed equation and see it solved

- look at a printed question and see it answered (within certain constraints obviously)

- look at binary, hexidecimal, etc. and see it converted to decimal

- look at a color and see pantone and hex color codes

- read existing printed books, but with access to immediate dictionary lookup, references, etc.

I could go on and on... if this ever hits, the ramifications will be extraordinary.

Your second-to-last point seems like a wonderfully simple, life-changing application- you can negate many of the problems of colorblindness by textually identifying the colors of objects and selectively enhancing the contrast between objects. (Perhaps overlaying textures or something?)

reader5000• 14 years ago

This is potentially awesome for two reasons:

1. I can lay in bed and read an ebook without having to hold a device.

2. Google can parse any situation I may be in and recommend the optimal action based on its data of every single other human on earth.

robin_reala• 14 years ago

I”m really surprised that no-one’s talking up the accessibility benefits of something like this. Imagine a version for blind users that dumped the screen in favour of a headset and mic. A little voice recognition and your glasses could tell you where you are, what you’re facing, and even do basic hazard avoidance. That sounds invaluable.

Actually, it sounds like the 90s kids show Knightmare :) http://www.youtube.com/watch?v=ciIfcYwI6Ps

libraryatnight• 14 years ago

I wonder if this will eventually intersect with the gamification trends. This article had me imagining a crude augmented reality MMO, routine tasks are assigned point values and so are items for purchase. Walking through the store you could see that Sara Lee white bread nets you 100xp, paying your mortgage on time, Bank of America has awarded you 1000xp. A look at someone and the HUD displays their level and point value along with their various badges. Of course check-ins will be automatic.

I doubt this iteration will be very advanced, but the article definitely made me think.

radarsat1• 14 years ago
