Available in the US from 2013, Google Glass Explorer Edition arrived in the UK in late June 2014 – still in beta, so buyers are ‘Explorers’,[1] and Glass’s software is continually being updated.[2] Glass will not be available for consumers generally for some time yet.
I tried a demo unit (linked to dummy Google account) in Google’s London showroom,[3] assisted by a ‘Glass Guide’. Offers to pawn[4] my immortal soul[5] couldn’t garner me a loan. I didn’t get to wear it outside, so couldn’t experience others’ reactions to Glass.
1. What’s Glass?
A £1000 (incl. VAT), Android 4.4 KitKat wearable computer inside a 43g ‘headband’, worn like glasses: 5MP panoramic camera (720p video), 12 GB usable storage, 670 mAh lithium-ion battery, accelerometer/gyroscope (not stated in the specs but there must be one given how it works), wi-fi and Bluetooth.[6] Processor and RAM are not mentioned in the official specs, but a public Google+ post stated that new units will have 2GB RAM.[7]
The titanium frame and nosepads are adjustable (press and hold). 5 colours are available (but no left-handed/eyed version).[8]
2. Components[9]
1. Bone conductor transducer (‘speaker’) – press it to your skull to hear more clearly. I had trouble although the volume was maxed, so the supplied earbud is indispensable in noisy settings. (The CPU and battery are inside the arm bulge – can get hot!)
2. On/off button power – inner side of headband. Press once to deactive/sleep Glass, press and hold to power up/down.
3. Touchpad – outer side of the headband’s right arm; a horizontal touchstrip rather than ‘pad’, stretching between components 2 and 4 in the diagram above.
4. Camera (the ‘shutter’ button’s on top) and microphone (black vertical strip, inner side)
5. Display (monitor substitute[10]) – a small transparent cuboid on a hinged arm. Look up to the right to view the ‘screen’; Google analogises it to looking in a rear view mirror (at least for US drivers). Once adjusted properly via the hinge, it’s like viewing a 25′ HD display from 8 feet away. Only a few lines of text are displayable.
Micro-USB port – beneath 2(ish), for micro-USB cable or earbud:
There’s no hard volume control buttons – although you can change the volume in Settings, while listening to music, or during a phone call.
Here’s another view:
3. Basics
You can only buy one Glass per Google Account. If you need prescription lenses, you can get a special frame free with your Glass purchase, which Glass screws onto (see photo above). Or free shades instead, if you prefer.
In the box: Glass, pouch, micro-USB to USB cable (for charging, or connection to computer to access photos/videos), mono earbud (+£60 for stereo ones), 2 pairs of spare nosepads.
Warranty: 1 year.
Battery life: meant to be a day; intensive use eg video recording obviously affects that. Charges overnight. Sleeps (screen fades etc) some seconds after you stop interacting with it, to save battery life; tap touchpad or tilt head up to wake it. You can’t change the sleep time.
Accessories (pay extra): eg shield, stereo earbuds, case, spare frame.[11]
MyGlass app (iPhone/Android):[12] effectively required, as some functions aren’t possible without it. Accessing the MyGlass web site[13] through a computer works, but that’s obviously less portable.
The automated setup process makes you accept Google’s Glass terms of use,[14] links Glass to your Google account, sorts out wifi/Bluetooth pairing, lets you add your top 10 contacts, etc.
4. Buy?
You need a Google account and credit card. Lasiked? Best check with your doctor first.
1. Google’s King’s Cross Glass showroom (locked, with beefy security guard).[15] By appointment only. But if you wander by and press buzzer looking pleading and winsome, they might just let you in.
2. (Better bet) buy online[16] – there are standard terms of sale.[17]
5. Play, not buy?
1. Get a demo – you can now book one via
https://glass.google.com/getglass/visit/GB
2. Buy, try, return within 30 calendar days for full refund (NB wipe it first!).
6. Controlling Glass
On wakeup you’ll see the home screen (strictly, home ‘card’) showing the time and ‘OK Glass’.
Voice commands: while viewing the home card, say ‘OK Glass’ to call up menu (nod up/down to scroll vertically); say menu option name.
Speak clearly and slowly, voice recognition isn’t perfect! When composing a message etc, it transcribes voice to text, but you can’t correct just the last word – you’ll have to start over.
Touchpad: used for many functions, eg tap to activate/OK/wake from sleep. Recognises tap and swipe forward/back/down (not up). Down means back/’escape’/home. For many menus you need to keep swiping for the next option.
Bluetooth keyboards may work, with tinkering.[18] Someone’s produced a touchpad-controlled on-screen keyboard.[19] People are working on remote controllers for Glass via Bluetooth,[20] maybe even full-size virtual keyboards (via bracelets).[21]
7. Functions/features
Glass is integrated with Google’s services, unsurprisingly. So, Google services will ‘push’ e-mails/notifications etc on-screen. Functions include:
· Search – say ‘OK Glass. Google[22] [search term]’.
· Browsing – you can view web sites found through searching, but not by spelling URLs.
· Watch/listen to YouTube videos (again, search for them).
· Make/take calls – works as a Bluetooth headset, if paired. Android/iPhone recommended.
· Gmail – get notifications of newly-arrived e-mails to read, reply, star, archive, delete.
· Send messages, photos etc – not just via Gmail but also Hangouts, SMS (Android only, not iOS). You need MyGlass to select email as a method. Talk, and text appears!
· Google Calendar – see events for next 2 days, edit events, etc. I’m told events can be added too.
· Google+ – view notifications, +1 or comment on posts, start or join video calls, share photos/videos with contacts/circles
· Take photos ‘with some software improvements, like HDR’ – 3 options (preview via a ‘viewfinder’):
1. voice command
2. ‘shutter’ button
3. (when that setting is enabled) wink. Warning: blinking may result in inadvertent snaps…
You can even take photos with mind control (by adding a biosensor EEG headset[23])! You can also snap’vignettes’: photos with the Glass display overlaid. There’s no optical zoom but developers have created some apps enabling digital zoom.[24] Filesize varies, could be 700KB->1MB
· Record video – stops after 10 seconds unless you continue it (no audio recording’s available, unless someone writes an app).
· Share photos etc – via Hangouts, Google+ etc; post videos direct to YouTube.
· Navigation/directions – see 10.
· Google Now – ‘in-the-moment information based on your Google Now Settings’, including Weather, Stocks, Sports, and Flights. Includes notification of Now reminders, supposedly even finding where you’ve parked your car. This function seems potentially the most useful, but there’s obvious privacy implications – no room to discuss them here.
· Translate foreign signs (Word Lens – amazing).
· Google Play Music – listen to your Play library music.
· Screencast to Android tablet/phone – mirrors Glass display via Bluetooth.
· Transfer photos/videos to computer – Glass behaves like a camera, when connected via cable. Only photos/videos are accessible in this way, but Google may change that if people would like access to other files. You can copy, rename, or delete photo and video files. However, renaming them will make them no longer available in the timeline (covered later). You can’t manage the files on Glass through your computer beyond that.
· Backups – when Glass is charging and connected to wifi, an auto-backup feature (enabled by default) will automatically sync photos/videos to a (supposedly private) folder or ‘album’ on your Google+ account (without deleting them from Glass), and also auto-update itself. I’m told that no other items are synced to Google+, currently. You can force initiation of backup manually. Stopping Glass auto-backup from automatically copying your ‘private pictures’ to Google+ seems much trickier[25] – a setting to disable auto-backup would benefit privacy-conscious users. Another issue seems to be that deleting media from Glass, to free up space, deletes it from G+ as well (ie it syncs rather than backs up), which may defeat the object of backups.[26] I’m told that
– an autobackup ‘clear’ function removes items from Glass that are already backed up, but leaves backups intact.
– deleting photos via a timeline card – deletes from both Glass and online
– deleting from Glass via connected computer – deletes only from Glass.
· Read e-mails etc aloud. It can also describe aloud what you touch, select etc.
8. Use
A ‘card’ fills the screen, eg home card, settings, calendar event notification, e-mail/SMS notification, photo snapped, news event pop-up. (Experimental) ‘notification glance’ opens the e-mail etc on glancing up after receiving the notification. When notifications arrive, Glass also chimes.
Texts and e-mails are copied to internal memory and the timeline. As stuff happens or you do things, cards get saved to a ‘timeline’. New cards ‘push’ older cards to the right. Scroll through cards in the timeline by swiping back/forwards. Related cards can be grouped in a ‘bundle’, eg Settings, upcoming calendar events. Cards are removed from the timeline in 7 days/after 200 cards. Check the timeline to view any notifications arriving during sleep.
9. Apps (‘Glassware’)
Unlike Google Play/iTunes apps, the Glassware Gallery of (Google-tested/approved) third-party apps[27] is accessible only through Glass + MyGlass. Glassware includes Shazam music recognition, Twitter, Evernote, Guardian and other news apps, etc. There are no apps yet for speech to text notes (although you could e-mail or text yourself a note), or PDF/e-book reading, and porn apps were banned![28] There’s help/info for developers, including a downloadable SDK (software development kit),[29] and current development seems particularly focused on medical applications.
Perfect vision or contacts is best. Myopic me couldn’t see anything without holding it over my regular glasses.
But, it’s not designed to fit over specs. So you need a special frame[30] (currently free if buying Glass, +£175 per extra frame); then go buy prescription lenses, pay specialist opticians,[31] pay again if your prescription changes.[32] Again there’s a range, including shades. MyGlass seems essential for some basic functions eg Gmail contacts, selecting how to send stuff (email, SMS etc – no SMS option with iOS). In my view Glass alone isn’t enough; ideally you need an iPhone or (better still) Android smartphone, to use Glass to its fullest with MyGlass.
It’s uncomfortable (even painful[33]) to keep looking up/right continuously. Google recommends trying it for 30 mins the first day, then building up. However it’s not meant for prolonged continuous use,[34] but for short ‘micro-interactions’, so as not to distract you too much while hot air ballooning (as you do). That’s why the display is small, Google says.
Even during my demo, a ‘Glass must cool down to run smoothly’ message appeared; it downed tools, needing at least a minute’s rest before working again. I didn’t time it, but my continuous use couldn’t have been for more than 20-30 minutes when that message appeared, probably less. Can’t see how you could video a full-length movie, despite cinemas’ fears!
Environment – with ambient noise, eg someone speaking loudly at the other end of the room, it’s hard to hear without the mono earbud. In bright sunlight, the display may be hard to see.
Navigation/getting directions requires a Bluetooth-paired GPS-enabled phone. Most other functions/apps need connectivity. For Glass to join secured wifi networks, use MyGlass on your linked phone or the Glass web site on a computer. Otherwise, Glass can only join open wifi networks (as there is no keyboard to enter passwords). But you can tether Glass to your phone via Bluetooth or wifi to use your mobile data plan, if your network allows it. A few apps don’t need connectivity, like Star Chart.
You have to trawl through the timeline to find things. There’s no timeline search, no structured way to access saved data eg ‘all photos’, ‘all emails’, etc. There’s no file manager eg to delete photos in bulk, even via MyGlass, though you can ‘clear’ all media stored on Glass in one go.
11. Security
The screen is transparent. People can see what you’re seeing – if they peer closely and can read reverse text. You’d notice! Similarly, they’d have to be uncomfortably close to hear anything, or to issue voice commands that would be recognised (voice recognition is not tied to the individual user).
To secure Glass better and deter Glass-snatchers:
1. Set a screenlock code:[35] a sequence of 4 steps, each comprising 1 of 10 different options: tap, swipe forward, swipe back, hook swipe forward, hook swipe back, each of which can be done with 1 or 2 fingers, giving 10,000 possible screen lock (or, strictly, unlock) patterns. Glass automatically locks after about 5 seconds’ inactivity, or on touching the power button, and if you’ve set a lock code then you’ll have to enter the correct pattern to unlock it on waking it after sleep.[36]
2. Set ‘On head detection’, so that Glass automatically deactivates on removal, whether by you or a would-be Glass thief (and it wakes on putting it on).
After 10 failed attempts to enter the correct pattern, Glass locks itself out for a short period of time, during which you can’t attempt any pattern. Each successive failure locks it out for a longer period. After 15 attempts, you’re locked out permanently. When locked out, you can go to the MyGlass site or app and unlock it from there – it will generate a barcode that Glass will scan to unlock.
However, be warned that photos/videos stored on Glass are easily accessible just by connecting it to a computer, even if you’ve set a screen lock code. Also, texts and emails etc are stored in internal memory. If someone stole your Glass, I don’t know how easy it would be to retrieve your emails etc too. If Glass offered full disk encryption (FDE) and you enabled it, that would scupper snoops or at least make their life much harder.
Google wouldn’t tell me if Glass has FDE or not, but given the accessibility of photos/videos through USB, I imagine not. As Android tablets/phones offer FDE,[37] I hope Google will start supporting this for Glass.
The good news is that apparently people using Glass in sensitive settings (financial, government etc) can program Glass to their requirements. For example, Google said developers could change the voice command from ‘OK Glass’.
Google may deactivate your device if you tell them it is lost/stolen, but that doesn’t delete data. However, Google says you can erase your device remotely via MyGlass or the Glass web site, which wipes the device as soon as it connects to a network thereafter. A factory reset is possible through the Settings also. I don’t know how thorough the wipe is – Google didn’t tell me if that zeros all (or indeed any) data, how many passes are used etc, and how easily retrievable data may be after the erasure. But reportedly a reset doesn’t fully wipe some other Android tablets or smartphones,[38] and no overwriting app for Glass appears to be available yet.
12. (Other people’s) privacy
People can see when the screen’s active (lit up) even from a distance. Though you could just be viewing a notification. They can’t tell if you’re taking a photo or recording a video unless you press the shutter button or wink. But any extra ‘mind control’ headset’s pretty obvious, and extending a video recording beyond 10 seconds requires tapping (though again you might be tapping to do something else). Glass can even be used to read other people’s phone/tablet passwords![39]
As for Glass users’ privacy (eg metadata saved with photos) and developer issues, that’s for another article (for space reasons), but I’ll say for now that I was told no GPS location metadata is automatically saved with photos – though date/time data are saved.[40]
13. Other questions[41]
Would you feel comfortable driving wearing them? Once used to it, and if it was in overglasses form (see below), I’d feel comfortable driving with it on, though I’d probably keep it in sleep unless I needed nav help. I’m not sure if you can disable everything except nav to minimise distraction (especially notifications), but that feature would be useful. For navigation while driving I’d prefer the screen to be top left or at the bottom, where checking it occasionally feels more natural than top right Top right might be fine for Americans or others where the driver’s seat is on the left; less so for UK drivers. Google’s terms of use has a disclaimer regarding using nav while driving; if I acted for Google I’d extend that to using Glass generally (not just nav) while driving, as notifications may be as distracting.
Does it make you feel constantly connected, or just connected whenever you wish to be? Is it intrusive / disruptive to your life having them always there, or is it just convenient? As it goes to sleep quite quickly, it’s only connected intermittently. Subject to the overglasses point below,[42] they wouldn’t feel intrusive or disruptive to me. If notifications would be disturbing during a meeting, you could just put it to sleep until you’re ready to receive them. Whether others might find it intrusive is a different matter! Anecdotally I’ve heard of someone removing them and putting them round his neck, clearly inactive, before entering the men’s room. That might be part of evolving etiquette.
I will cover some other questions, mainly on data and content rights, in a separate future article.
14. If only…
No frame is available that is designed to fit over one’s regular glasses. A Googler suggested that perhaps overglasses were thought unfashionable. True, some overglasses are functional,[43] but others can be quite blingy.[44] And some people can’t or don’t want to wear contacts or buy another frame just to use Glass.[45] I think more people would buy Glass if an overglasses version were made available, at least for the general consumer release.
Personally, what I crave is a sub-500g laptop replacement for working on the move.[46] To me, Glass’s key innovation is that it obviates the need for a large (and heavy) physical screen, producing similar results for users through projection. I hope that eventually, as batteries become lighter, Google will release an overglasses model with:
· much bigger screen (as seen by users) – particularly for those of us with ageing eyes
· different design, hinged so that the screen can be moved into the middle of the user’s vision (much easier viewing than up/right) when desired, and moved back to the side when not.[47] That would enable users to read War and Peace comfortably on Glass – some would want to!
· support for fast input via a full-size (but light) keyboard – whether portable Bluetooth or virtual keyboard using (not heavy) bracelets/rings
· apps for reading and annotating PDFs, ebooks and other documents – and ideally writing/editing them too, eg Office for Glass? (in combination with full keyboard support, of course)
· much longer battery life, and a processor/apps suited to extended continuous use, and
· full disk encryption enabled by default, at least when you set a lock pattern.
Easier searching and file management would also be good, perhaps via another ‘remote control’ device such as smartphone or computer (but with adequate security).
The above represents my own wish-list, but those of others will differ. A friend who’s a keen bird-ringer would love to have a voice-activated, voice-output, wearable computer with the BTO app,[48] so that while your hands are occupied handling a bird you could say ‘Fieldfare’ and the computer would say and display ‘Fieldfare: Full grown ring C, Pulli ring C’, giving you the info hands-free – and ideally you should be able to scroll via voice alone too.
In terms of possible ‘legal’ uses for Glass, Neil Brown has suggested a few:
· simultaneous translation of foreign language documents: as you are looking at a document, Google Glass converts the particular paragraph to your preferred language — perhaps enough for getting a gist of something, if tuned with a legal dictionary.
· But this isn’t possible yet – Word Lens is excellent, however it only works on quite large text, ie on signs. Hopefully in future the camera and app will both improve enough to make this possible.
· as you read through a document, it captures the text, OCRs it, and turns it into a file for you to edit — perhaps even ‘dictating’ notes as you read, which are then appended to that digital file for subsequent incorporation.
· Again, if only! This expands in more detail on my own document reading/annotation wish-list item. OCR seems dependent on camera quality and app availability, especially as they would have to cater for any unsteady hands holding a document and, as previously mentioned, an audio note transcription app is not yet available (which would need more fine-grained error correction than ‘start all over again’ if one word is transcribed wrongly).
· advocates in court, so that others can ‘pass notes’ to them without having to shove pieces of paper around.
· Yes, this is possible by sending an email or text to the advocate. It would be great if you could quickly put Glass into ‘restricted mode’ in court, a kind of filter that lets through only important messages from (pre-defined, editable) contacts or groups of contacts, to prevent too many distractions in court or indeed meetings – then disable restricted mode again when you’re out. It would be interesting to see if courts ban Glass, even for open sessions.
· a presenter’s notes available to them on a per-slide basis, just a quick glance away; no more need for shuffling papers in the hand, or looking down to a screen on the floor, tying you to one place on the stage. Or even just the ‘next build’ for the current slide — moving the presenter view right into the presenter’s view.
· Again, not possible yet, see my wishlist item on ‘Office for Glass’ – but hopefully one day!

16. Verdict
As Google makes very clear, Glass is still in beta. Developers with an eye to the future of computing will certainly want, indeed need, one. As for everyone else, those earning below partner/professor/’head of’ levels might understandably balk at paying £1,000 for a beta product, unless of a pioneering bent or won over by the cool factor.
Personally, I’d happily buy one even at that price – but only if and when my wish-list features are incorporated, because a laptop replacement is my own ideal use case for Glass, and yes I’d don bracelets and not care how it looked! Until then, I’d consider Glass should the price be significantly reduced, but it’s probably of most benefit to Now and Plus users, and I’m not big on either.[49] So, for the features Glass currently offers, my smartphone is good enough for me, for now.

[42] Glass wouldn’t stay in place without my holding it over my specs. I can’t see without prescription lenses, and multiple prescription frames would be too expensive for me!

[45] Personally I’d have to buy another 2 frames just to use Glass. Were an overglasses version available, one unit would be all I would need.
[46] Yes, I meant sub-500g. Sub-1 kg is still too heavy if you’re short, feeble, unfit – and/or have back problems. Teenagers, kids and some women would relish full computers weighing under 500g; even some men have bad backs.
[47] And even further in the future, get the screen to move into the centre automatically with a voice command, and out again with another!

[49] Now for privacy reasons – I’m still unclear exactly which parts of Google’s privacy policy apply to Now. I want to know details of what info it collects, who gets it, and exactly what they do with it, not vague/general purposes, so I don’t use Now on my Android tablet.

If it had allowed pseudonyms from the outset I would have tried it and maybe even moved on to using it with my real name, but currently I don’t have the time/energy/braincells to make the effort.
