Late yesterday, some of us were able to try once again Microsoft's HoloLens here at Build 2015. This experience was my second time with the wearable holographic device, and 99 days since its announcement, Microsoft has made some significant strides. You can read about my January experience here.
For one, the HoloLens device we were able to use this time was the near-finalized prototype. The version we wore in January was a computer around your neck and a mishmash of hardware used for testing purposes.
Personally, I find it remarkable that this thing even exists. It truly has no wires or tether. In terms of weight, it is not light but it is far from heavy. Since it is well balanced in terms of weight distribution, wearing it on your head feels fine. My motorcycle helmet is much more cumbersome, by comparison.
The big feature Microsoft was demonstrating this time were the Unity and Visual Studio coding tools. Since HoloLens runs off of Windows 10, it takes Windows 10 apps. These tools mean any developer can now make an app that runs on Xbox, PC, phone, or even turn it into a hologram.
The developer tools were only finished last week, and as such were a little rough. However, we were able to implement audio, gestures, speech commands, initiate spatial mapping, and then we compiled and deployed apps to our HoloLens. While many of us in the press did not of course write our own programs, earlier in the day, real developers did in a longer four-hour session.
This stuff is all real, folks.
Some early complaints
Watch the video above to see my immediate reaction to wearing and using HoloLens, including some criticisms.
In short, many of us in the media thought that many aspects were exceptionally well done e.g. gestures, voice commands, spatial mapping and spatial audio effects. However, the one things that bothered many was the limited view of the holograms.
By comparison, in the demonstration and promo videos for HoloLens, users appear to be walking in a world where holograms are surrounding us. Technically, this is true. The real experience though is you only see holograms in your direct line of sight. It's akin to having a tablet in front of you with media on it, but sometimes you cannot even see the whole hologram without moving your head to 'scan' for it.
The lack of holograms in your peripheral vision is just an odd experience. Someone of told me it is similar to wearing transition lenses, which also have a similar, limiting effect. In fairness to Microsoft, this is likely just a limitation of the technology and size constraints of the lenses used in the device. Paul Thurrott had heard but was unable to confirm that the hologram field-of-view was purposefully kept smaller to reduce motion sickness (something common with VR headsets like Oculus).
This complaint is more of a contrast between expectation and reality though. Once you get used to this direct line-of-sight view and moving your head to see things, it's not bad. It is just not how we normally see things in the world: objects stay in our peripheral, even if we cannot 100% "see" them in full detail.
Either way, 1.0 version of such technology will have limitations. The fact that this stuff exists, it is coming to market (when and for how much is unknown), and the developer tools for regular developers are almost here is quite remarkable.
I do not quite think this is a straight consumer device like an Xbox One just yet, however. Instead, I envision Microsoft releasing it to industry, artists, engineers, schools, and hospitals first. After a few iterations and as the price comes down, it will trickle to the mass consumer market. Microsoft, however, has not yet defined their plans for HoloLens, so we will have to wait and see.
Special Edition - Windows Weekly today
Want more of my reactions to Build 2015? Join me later today as I'll be live, in the TWiT studio to do a special Build edition of Windows Weekly with Paul Thurrott and Mary Jo Foley. You will not want to miss this show! We'll post more info later on where to watch and what time (2pm PT).

I tried the near-finalized version of HoloLens, this is what I think
Daniel, a question, if i may. I noticed that in a few of the demos, there was a mixture of translucent and opaque objects. e.g. Some controls seem to be semi-transparent while things like videos creens and the robot thing that was half-built seem completely opaque. DId you experience anything like that or did everything have that semi-transparent look to it (like using the "Add" blending mode in Photoshop)?
I was thinking it would be the latter, but that doesn't make sense in the context of the demo material, and after some thought it occured to me you could use an LCD substrate like an alpha channel, to partially or completely block out the background, just as a normal LCD display blocks the backlight to make black. If they are doing something like that, HoloLens could function perfectly anywhere, even while staring at a white exterior wall in full sunlight.
@Daniel is it like this http://www.wired.com/wp-content/uploads/2015/05/hololens-mockup.jpg
I Think Magic Leap has somewhat less of this Restricted Field of Vision found in Hololens v1. You can check that out here:
https://www.youtube.com/watch?v=kPMHcanq0xM
That's not even a demo, it's a promotional video and you can't take much from it at all. Magic Leap probably don't even know themselves what their FoV is going to be because i doubt they even have working prototypes of anythign even close to production ready.
Actually they would have known about its FOV, but yes as its just an promotional video we cant judge about their product or it's features right know. And as uptil now they hasn't shown anything about their product, they r mostly a hype until know. But as they show it in promotional video, (u can't hv that gameplay with limited FOV therefore they might not be sticking with limited FOV to make that work) if it is anything similar to that it would seems good
So then what was the demo we saw at build? It didn't have that problem.
I'm wondering if people might get sick of using the HoloLens after prolonged use. Had the uncanny valley in mind ..
Can you make a demo pointing your camera in front on the perspective of the wearer so we can imagine how would it feels and looks to be using the Hololens?? Is it possible?
So was it worse than previous iteration? That's what others are saying.
Seems the second time around has most who tried the prototype in January somewhat less impressed, in particular about the FOV.
Oh well, early days yet.
Thanks for sharing your experience with us, that was great to know how exactly this holo lens work, still beta, but Microsoft needs to deliver the final build as it should!!
Is it just me, or is anyone else not seeing the difference between this and augmented reality?
any news about the price ?
also the battery (how long it will stand)?
And for this problem you talked about,,small screen,I saw a video in the verge Chanel they explained more about it and I didn't like it. It's not like what we saw in the demo is it somthing that can be solved in final version? Maybe extend the screen project in full of the glass or make the glass bigger
It's still a long-way from being market-ready. I'd doubt anyone's going to commit to a price or battery life yet.
And to be fair, neither of those things are important - it's a freaking Hololens - take my money!
I can't wait for the military to get their hands on this
Military have had similar things for over a decade. Pilots especially.
These things still make me think of Firefox (not the browser, the book/film).
Dan your to picky. I want one. I'm a consumer. I wear glasses. Will I need contacts? I'm sure I'll get use to moving my head. I do now fi want to see ;)
Daniel, how wide was the field of view in terms of degrees? Was FOV wider in January's demo?
once they finalized it and tweek the software i believe the peripheral view can be adjusted to the user. if not in the first version but in the later version
Still remarkable, I think too many tech jur-NOs are quick to dismiss this as bluster without considering that there are going to be trial and error concepts, seeing how this affects people using it for extended periods, and the smaller field of view is the HL's team playing it safe, I suspect. I also guess that this will be a very limited production run, when they decide to go ahead.
Also wonder, if there will be a full resolution 180 degrees screen.
Will or brain adapt to physically see full resumption 180 degrees in the real world?
Or another question, evolution chose not to give us full resolution for obvious reason.
Now that the evolution pressure is off, Will we be able to see fill resolution 180 degrees and if so how long will that take naturally or with some generic help?
Let us know how cool the BSOD is on this thing.
Oh yes!
I agree
I wonder, can't you stick a low resolution 180 degrees screen on the unit?
I hope they improve the depth of field before releasing it, that's a real deal breaker for me, I would rather settle for a VR helmet if that were the case
I can't look at VR anymore :( AR is all I ever wanted.
HoloLens is still in development stage. The final product may be just like the one they demoed it. Don't come to the conclusion yet.
Look off-axis, and the holograms disappear? Did somebody watch The Last Starfighter one too many times?
I totally agree with Daniel. I was also first disappointed in the limited field of view at first. But soon I got accustomed to "scan around" with the head to se the whole picture. This limitation had me thinking twice about getting the first generation device. The FOV issue must be on the drawing boards for Generation 2. Maybee Gen 1 will be fine for professional use but a gen 2 with better FOV will be the next home gaming appliance?
Anyway, just realiszing that this thing really works is kind of a shocker! Good Work Microsoft, and big cogratulations to Alex Kipman and his team whos delivering this marvel of technology!
Se you in Petaluma Daniel in a couple of hours!
I am not going to watch Windows CrappyWeekly. but thaks for the small review Daniel. your complaint doesn't seem something that can't be fixed someday (you can blame it on weak people using VR headset like Oculus).
But even Autodesk seems like it's integrating Hololens in their products so it's a good thing big companies are seeing good things about hololens. it only needs to be released and time to see what developers do with it.
"Some HAVE told me..."
Besides that, I can't wait to try out the HoloLens.
I'm _SO_ excited about the possibilities for this. I work in a media studio, and just the ability to put multiple virtual monitors and displays around you in the control room during a production would be so helpful - especially since you could (with the right programming) tailor them to the particular production type.
I'm sure future iterations will have a wider field of view, starting with multiple 'flat' sections off-axis to the center, follwed by a single curved panel that gives a more full ~180 degree field of view, but I'm excited enough about getting my hands on v1.0.
So, it's not a portable HOLODECK? GET OUT OF HERE!!!
Seriously, this is remarkably impressive stuff. I suspect the reason we "saw" all of the holograms everywhere in the demos was because the camera guy's equipment was sufficiently back far enough to see it in it's field of vision. I'm certainly glad someone is pushing us into new tech. A/R and V/R are neat but have obviously different practical uses and as a result potentially different initial customer base. Can't wait to see how this all pans out. This looks like it should be expensive (no matter how much we hope it isn't) unlike other A/R devices. So excited!
What i understood from kipman's interview tht they kept hololense as eye for camera used in rig to show audience what user who is wearing is seeing. If thats true than how can field of view is small
Tvs week be extinct in 10 years tops!
Daniel the lenses you were being told it was similar to would have been varifocal lenses.
so can i run photoshop on this ?
battery life?
brain cancer if it receives internet via wifi, or in the future cellular wifi?
can mirror my XBOX ONE on this?
It should be able to run the Xbox app, so I'd imagine so
Not to diminish the importance of your questions, but you do realize that radio waves and EM fields are every where as a result of the ubiquity of wireless, cellular and pretty much every electronic device made? :)
On a serious note, they've shown applications that can project on this such as Netflix, and what not. It would be neat if regular 2D Win32 applications could also be projected even if its just like a flat window (like the Netflix demo) and you could interact with it by zooming in and select pen controls using motion/mouse gestures.
If HoloLens "is" Windows 10, and Windows 10 devices can receive streaming games via XBOX One, I would hope its can be a receiver, too. I would wonder about battery life at that point though.
Can't wait to learn more.
i am aware of them being everywhere, but a huge concentration of cellular signal going to a single area can potentially harm you. here's a video of a girl who kept her cellphone in her cleavage and at a young age she developed breast cancer.
https://www.youtube.com/watch?v=rSpCB1f4oQk
lets not forget exploding. cellphones. they happen, and theyre reported at least once a year from both apple and smasung phones. now imagine hololens exploding on ur head.
There is no scientific proof. If that video example were even close to the truth, you would see a lot of people with cancer. After all my sister has put her phone there for over 10 years. Exploding devices might be a concern with cheap ass manufacturers, but I don't see MS doing that. Can you imagine the lawsuit they would face... Yeah, not gonna happen.
Daniel, you certainly have the right haircut to wear tis device. :P
Nice video thoughts on the product, I hope they fix the view before release, it would make it more relistic. The concept is cool but, if you look a little off axis, it would be a big disapointment to lose that view...
With that issue alone, it would make me want to wait on the 2nd version that comes out a year or 2 later...
I wonder if they have plans to adjust for it and fix it...I'm sure it's a clear display of some time they use for it, so just getting a bigger one that kind of wraps around the whole glass lens would fix that, no ?
Still, looks awesome and I am looking forward to trying it but, when I actually go out to buy one, I want to to be a true final tweaked version, not a beta version that it's looking like your getting in those demos.
Have they said anything about the price point they are trying to hit on it ? If part of it's sale is going to be a addon to the Xbox one, then under $300 would be the magic price point (I picture the $199.99-$299.99 price for Xbox one) and they would sell a ton of them but, up over $600, it wont sell as many. And even less if it's over $1k, at that price, I would really have to think about it, there would need to be a TON of apps and games available for it. This would also limit the software avalabity of it, as devs are not going to create games that will only apply for the wealthy people.
So far looks good but, still a long way from release...
The price of the HoloLens will not have anything to do with games for it. It runs Universal Apps. Any app for Windows 10 will run on HoloLens. Apps that run on HoloLens will run on your phone or your laptop or your tablet. Software availability should not be an issue here.
You are looking at the price wrong by associating this to XBO. They made that mistake once with Kinect. No need to repeat it.
As mentioned before, this is an independent device that doesn't rely on anything else. So if you're thinking about $300, you are very mistaken. The future doesn't come cheap. If "toy" phones can be over $700, why would you expect this amazing device to be cheaper? For the record, cheaper would almost guarantee it to be a hit. However, let's not set ourselves for disappointment with unreasonable expectations :)
shoulda ran n took it home
Great summary Dan, thanks!
Šejtanska posla, very interesting. Thanks for the info.
Connect this thing to cockpit avionics to give me a heads up display of instruments/terrain/obstacles/waypoints wherever I look when I'm flying.....one day.
The Eurofighter Typhoon and pretty much all modern fighter jets have had HUD's projected on the visors for well over a decade. If you play the jet mission on Battlefield 3 they have it in there. You can lock missiles oto aircraft behind you. They even have cameras looking at your eyes to track the relative positions of your pupils.
To be honest all this Hololens is just an upgrade from that. Though the untetheredness and mobility is a bit more of a break through than the actual "Hologram" bit.
Did they announce how much it will cost?
Apparently more than a games console.
Which could still be less than a flagship phone. Though I doubt it. I'm seeing this being released for around the same price Google wanted to sell the Google Glass if not more.
No
I confess I'm a bit disappointed it's not an emersive at least 180º experience BUT I can't say I'm surprised. It's new technology, it'll take time but I believe we'll get there.
And I'll probably seriously consider getting a HoloLens once it's released. It'll depend on what exactly we'll be able to do with it. But it's promissing. Very promissing.
Now if Microsoft could start working on holographic tech Star Wars-style, THAT'd be awesome.
Unfortunately, none of the current VR is fully 180 degrees, our eyes aren't even 180 degrees, we're not fish.
Well, first, this isn't VR. These are holographic projections. You still see the World around you unlike VR where you're just seeing a screen.
Because this isn't VR, it means you keep your field of vision. And your field of vision, although not reaching 180º, is wider than just looking straigh forward as it happens with VR where you need to be looking at that specific screen.
That's why I thing the path forward will be to expand the field of vision of the HoloLens to somewhat closer to 180º so that you can keep being aware of the virtual objects surrounding you.
Agreed, over the the product looks interesting but, as I said below, The display tech is prob one of the OLED clear displays, if they can find a reasonable cost option to make these a little bigger to cover 95% of the viewable area (where your eyes can see from a fixed product like that), It would solve the issue.
I'm a little disapointed to hear that too, wondering if I should wait for the HoloeLens v2 as it might fix that...
>Now if Microsoft could start working on holographic tech Star Wars-style, THAT'd be awesome.
Not sure it would be just awesome, it would be freaking EPIC...(epic trumps awesome) :)
I'm conserving "Epic" to use when it actually happens ;D
That stuff they were showing on stage was pretty amazing. Are you saying it is not like that?
What you need to understand is that what we saw was via a secondary camera rig, basically in the third person. As the holograms exist but they wouldn't be visible in your peripheral vision (first person).
Edit: Simply put, its like looking at the street through a Window. Where you need to turn your head to see in either direction. For instance there is a lamp post further down, but You cant see the lamp post without directly looking at it.
Lots of head movement... It could be weird for the first time but we'll get use to it
Can the limited field of vision be because ou didnt wear the device correctly? I rememebr someone saying that microsoft says that its not different from what you tried in january.
That was a big complaint in January too. I think once people realize that they need to think about overlays, and not objects waiting for them it should help.
Is it as good as virtual boy?
I see what you did there
Posted via the Windows Central App for Android
I hope they make a spartan helmet edition. I just want to wear that with an augmentud HUD for Halo 5 and I will be the happiest person on earth.
Do the holograms just disappear as they move put your FOV or do they fade or a similar animation. If not the latter maybe that'd make sense?
If you look at the service, you will see the screens, similar to glasses. I would assume the holograms display to the edge of these screens, and drop off when they leave the screen.
can you wear glasses and this at the same time?
That's what I want to know! Us glasses-wearers need this info! Maybe they'll release a version with no nose pieces so we can wear our glasses underneath?
If you watch the video above, there is something to adjust for glasses.
Yes, watch the hololens demo nearer to the end of the first keynote.
You can wear glasses with it, yup. It adjusts (pulls forward) for that.
Yes, and Its fully adjustable.
So basically its like pixelsense(surface) not yet ready or cost-effective for home use
Can't wait till it's finalized. I hope they give a wider viewing angle.
My wife agrees I need this :). Seriously the value will be software driven. Bring it on. Oh and eat that Apple watch.
I analyzed your face when you said "Microsoft is definitely getting ready to sell this sometime, hopefully this year". I bet you know more... Oh, and nice sweater. ;)
And that what makes this a blog and not a news site. A shame there isn't really a tech news site that digs for answers, I guess Gizmodo does that sometimes, but they are also super opinionated.
What defines a "real" news site in your opinion? Not all information is free to reveal to the public you know.
Reporting is getting the truth, not just accepting it and then repeating it. Basically, investigation, not invitation, or more like science, not religion. Any site can reprint press releases, give opinions of them, and also do reviews.
I get that is hard in tech because many things are trade secrets, people don't want to lose their jobs, etc. That's just what it is.
If you have information you can't revel you might as well be getting paid by the people stopping you from reveling it otherwise you know just to know, and what's the point of information if you can't use it?
Except this whole thread is bullshit.
Give me a freaking break. We signed no NDAs, we can say whatever we want. I have no idea on what their plans are for this device, pricing, timeframes, etc. I'm not holding back on that because no one in the media knows this.
My hunch is the holiday season, because, duh. My other hunch is Microsoft is still feeling it out on how to sell and market this thing.
The rest of your post is just verbal masturbation. Although I do love it when people not involved in this "business" pretend to know how it works and then to go further to tell us how we should be operating.
Nothing condescending or ignorant about that, no sir.
You admitted as much when talking about updates and devices in the past. I'm not trying to be disrespectful, I love this site, I just know the difference and wish there was more money in sharing the truth rather than hiding it. That's true in business and politics. The op was teasing, I was venting.
So do you think I should buy it and will be satisfied?
Posted via Windows Phone Central App
Yes, there is clearly enough information available to say you should buy and will be 100% satisfied. /s obviously. I hope that the wasn't a serious question.
Not 100%, the "small rectangular vision"thing is a letdown
It is a serious question. It has great features but flaws that could be a deal breaker.
Posted via Windows Phone Central App
If it was availble today, I would wait, the product is only as good as the software is, if it takes a while for a library of software to be availabe, then I would wait...
If you got one today and there was only 3 programs for it, it would be cool for a week or 2, then it will sit on your shelf collecting dust...
I don't think so. remember you have Windows 10, and Skype on it, along with outlook and few other software. So even if it comes with 3 or 4 software(which i beleive it will come with a lot more), you can still do many things with it, till more software/apps will come to it. remember its a full computer. You can even watch videos, Office, Skype, play games like minecraft and more................and alot more on it. the things Hololens can do will be limitless, as soon as you buy it. it will NOT sit on a shelf, i can assure you that. This is NOT an overrtaed,...... TOY that CrApple sells, with an stupid EVIL fruity logo on it.
Dude it runs Windows 10 Apps ! So pretty lot of Store Apps will run in a standard presentation, as well as basic Video.
For us Developers this is an awesome new field to develop against. Just dive in and create new experiences.
Everyone in my living room got wet when they saw that medical demo of the guy with the huge package
Dan, can you answer a question that no one seems to be answering: do the images exist in focus with where they are in space or are they just overlays? In other words, are they using light field technology or just a simple video overlay?
Not too sure how to answer you but it's closer to the video overlay, objects get further away but are always in focus if that helps?
So jealous, I'll be a little disappointed if this isn't brought to the consumer level fast! However on the other hand perhaps a v2 consumer level will have a better field of view!
Hopefully, and it might even get fixed before the first release. Not likely tho...
Really looking forward to today's Windows Weekly! Screen Savers returns on TWiT.tv too!!!
Me two always watch the ones with windows central crew.
The most important takeway of this article: Dan drives a motorcycle.
Also, that a HoloLens would make a great integrated tech for a motorcycle helmet. HUD anyone?
yes, Yes, YES!
Dude! I'd want to buy a motorcycle just to get that HUD! Awesome idea! GPS Navigation by hologram HUD? Awesome. Skype phone call on the road inside your helmet? Awesome! Too many uses for that. Someone has got to do it.
Racecar driver helmets? Yeah! Identifies other cars on the track, locates stray debris, etc. How about a hololens for a driver at night that helps spot deer on the side of the road and alerts the driver? That kind of stuff would be great for safety.
Skype Video while driving? Who asked how you could die waering a Hololens? This is it!
HUDs for driving, eigther for motocycles or cars, have to be very limited so that they realy support instead of distract you. They should help you to keep your attention on the road. Therefore holographic navigation could be a good idear and so is augmented reality with nightvision or infrared sight. But that already exists build in into the front window of some cars. But for shure this could be improved. I'm just not shure if I'd like to wear a Hololens while driving for hours on Autobahn.
Already done with Android. Check out Skully helmets. HUD with rear view and GPS nav.
http://www.skully.com
They run about $1500, so careful what you wish for.
IKR?
+10 sexy points, Daniel.
Journalistic approach is starting to remind me of Jason Mick at DailyTech. It's not to the point that I can tell the author just by reading the article title yet though.
So if you die in the HoloLens do you die in the real world?
No... You just wake up.. Holoception!
Yes you will die.
Only if you take the blue pill.
Hahahahhahahahahahahaha
*Attaches the "I understood that reference" Captain America gif*
How would it be if one dies in real world playing Minecraft wearing Hololens? What a terrible thought XD
It's just the Universe defragging itself.
You will die then fade away.
Yes, The body cannot exist without the mind...
Lol you will die in mine craft .
Well, since there's no "Akihiko Kayaba" working at Microsoft, methinks you're safe.
(Though this thing looks more like the amusphere if you ask me...)
If you wear it in front of a moving bus
I'm with Saras112. Daniel. I thought we were friends. :)
What does it basically do?
Displays holograms
How. Does it have a memory in which objects are stored or by simply thinking or what.
It's a wearable computer. It responds to eye movement, voice commands and hand gestures. It's mapping your surroundings and understands them as 3D forms, and can then seat virtual objects on them. Any ordinary app can become a 3D object in this world, either as a complex form or as a flat rectangle of whatever you'd see on a normal screen except you can turn it, stretch it and click it with your finger as a pointer.
Nice explanation
This was a GREAT explanation. Its a computer on your head, with some unbelievable sensors and parts. When i saw it few months ago, i was in WOW, and I'm still in WOW. This futuristic device has lots of potential, for MANY different type of uses, all over the world. Now this a game changer device, NOT a garage MacCrap book, wanta be Killer PC.
I wonder how long before CrApple COPIES this AWESOME device AGAIN and tell the world they invented iHololense? Remember when Mr. Bill gates introduced the 1st tablet PC in 2000? Now if you ask any iSHEEP, they will tell you CrApple was the 1st to have tablet in 2010 and Microsoft surface was a copy(at least 1 in 10000 or so may know, CrApple did NOT invent ANYTHING whatsoever, and everything they have is a COPY from someone else).
Hahaha nice lecture
its the truth. CrApple=Copy, then lie about it.
Apple doesn't invent anything. They take existing technology and design it better. They don't cut corners either. If I could thank them for one thing, it would be moving the industry to refined metal chassis instead of the same cost cutting sheet metal and plastic.
How about Cortana as a hologram
That's a given, although her attire may be a bit more modest.
Maybe it'll be user "configurable".
LOL! If you are the one, how do you 'configure' her?
Soo jealous
Right?! I'll only be able to do this months from now.
Awesome wish I were you.. I'll buy it in India here
Just to be first, just to be first...
I'm really disappointed with the "rectangular vision" thing
It's required to direct the light to ur eyes. This is not like 2d pixels its way beyond that
Lol no that's not true. In January, it was in your peripherals but this past week it wasn't.
Likely many factors. Cost is a big consideration. Keeping the cost low enough is huge as to whether the adoption rate will be high enough. Safety, nausia, etc. likely also came into play. There may be other gaming only versions down the road with better side vision.
If this version of the HoloLens was $500, I would rather pay $1500 for the version described back in January. I hope the team goes back to the drawing board and at least expands the field of view to something that the press isn't going to bash upon release.
I wonder if safety is a considering factor with the limited hologram peripheral vision. I was wondering watching the videos of them walking around in a construction zone with holograms overlayed in it how they know not to walk into walls or into holes. Seemed kind of dangerous.
You can still see the real world around you.
Posted via the Windows Central App for Android
That would be self defeating as well. If it doesn't 100% opaque the real world behind the hologram, that's a bad experience. If it does, you risk walking into something.
