Epson Moverio BT-40 Smart Glasses Review + Future VR support?
Вставка
- Опубліковано 13 кві 2021
- A brief overview of my experience with the Moverio BT-40 Smart Glasses.
Some additional notes:
Unity - A unity plugin exists for the glasses, though it targets Android.
Sensors - In addition to the ambience and compass/accelerometer/etc, the SDK indicates that there's an API to detect when the user taps on the side of the glasses. This could act like a button press much like it was done on Gear VR.
3D Mode - Enabling it on a PC or phone splits the incoming video in half and sends each half to a different projector. This is compatible with any side by side video content.
PC Control - A Moverio SDK is available online and comes with compiled binaries for the sample apps within that allow you to control the glasses.
USB C Displayport Adapter - Dell / SUNXI make the UPD2018 PCI-e add-in card for converting a displayport signal into a usb-c DP alt mode signal. If you can't find the card with a full-height bracket, a 3D printable bracket is available here - www.thingiverse.com/thing:480... - Наука та технологія
Thanks for such an informative video, I usually don't comment unless it is worth my time to, you have really earned it!!
Nice informative video, thank you. Wish you made more 🙂
Great, thanks for the info!
Thanks for the video. Can you give more information on how to side load apps and root the BT-300 smart glasses.
I've tested a Dell WD19 dock to charge my device and use the BT-40 simultaneously. While it works with the BT-40 on my PC, my Galaxy S8 doesn't appear to work. I don't have a newer phone to test on at the moment, but will update if I do in the future.
I have SteamVR mode working (and have had it working for some time) but have not yet made a showcase video and am not quite ready to release the code for it. Hold tight.
Hi Erik,
Great video!
Has there been a specific HDMI to USB- C adapter that has been determined to work with BT-40?
Wacom Link Plus?
Wacom Link?
Other?
Thanks!
Mark
Good review.
Question - I've been looking for something like this as a golf app that I could pair with my phone camera on a tripod. Many avid golfers will take videos of their swing and then analyze it after. What would be much better in my mind is to be able to work on your swing in real time without having to stop and see if you are doing whatever it is you are working on correctly. Your thoughts on this would be appreciated Erik.
This sounds fantastic for drone flying! I have BT300 glasses, but they don't support the latest dji drone apps. These bypass that issue!
@@Servili007 one catch...the dji controller also needs to plug into the USB c on the phone...so a splitter is required. I have put an inquiry into Epson support. They tend to be quite good.
@@DonJoyce This is one place here I'm still waiting for adapter manufacturers to catch up. I've heard of some wacky solutions for certain devices, but I'd like a really simple USB c hub that still passes through video on one port. One would handle your use case, for example.
Mine came in today and I would give them a 6/10
Definitely not a perfect device quite yet. What were your pros and cons?
@@ErikServili ok after some time it turns out I love the device when comparing it to some others! It's super small, and easy to use. The other brands get super hot, load, heavy and bulky. Epson is now my preferred headset.
Hey Erik. Have you played with the "Pixcell shift amount" values in the Moverio SDK? I'm using the BT40, and I'm finding text a bit too blurry. As there isn't any way to physically adjust the angles of the projection or lenses on the device, I was hoping that there might be a way in software.
I haven't really played with those values, but I could check them out. Are you finding text blurry across the whole FOV or just at the edges? Is your feeling that you need to manually adjust it due to having an IPD far away from the average?
Thanks for the explanation!
Do the Epson Moverio models BT300, BT-35E or BT40 allow for use with Xbox or Playstation consoles.
The BT-35E do out of the box using the control box. The bt40 would need a wacom link plus for that. The bt300 would need an otg cable and USB HDMI tuner for that.
Hi.
Do you know if there is an adaptater that enable use the bt-40 with a hdmi cable in Input ?
You'd need a Wacom Link Plus
Thanks for the follow up video. About how big would you say the screen is, and what distance does that apply to?
it's just under half the diagonal of that monitor in front of me in normal use. (so just under a quarter of the total screen area) Though since it's in both eyes it feels a bit bigger. To put it another way, it's about as big as a 65" TV at 8 feet
Eric, im interested in getting these for drone FPV [I mean for normal drones that dont have dedicated FPV display liek say Air 2 or any drone that has android app].
I have old ASUS ROG2 phone and it has two USB-C ports, one on the bottom USB 2.0, and one in the middle of the device its USB 10Gbps [also this is the one for the video out], they both can charge the phone and transfer data.
Do you think ill be able to both connect the glasses to the video port and connect the drone controller to the USB 2.0 USB-C port?
This is a hard one to answer, but I think it would work. Is the usb connection for the drone handling the video stream or does that happen over wifi? If it's over USB, I would look online to see if it's running at USB 2.0 speeds or 3.0 speeds. If it's only using 2.0 speeds, then I don't see why it shouldn't work.
Hi Eric, thanks for the great video! Looking to get a pair, my usage will be coding and general computer work on an external screen while traveling. Have you been able to make any progress with the head tracking? I do have a pair of Tap system's wearable keyboards with a poor optical sensor for the pointer but would very much prefer tracking head motion instead...
I did have something basic working by tying it in to opentrack, but it wasn't really shippable in its current state, and for your use would require you to run something like steamVR+virtual desktop and a dummy plug to use the desktop view how you're describing it.
@@ErikServili I see, thank you for the response. I'm not sure how this works but imagine there are some 3D coordinates that need to be sent over from the glasses and translated onto a 2D plane like the desktop but not sure how the "dummy plug" and "steamVR" are involved and why this would require a virtual desktop instead of interacting with the real one by translating the coordinates to cursor movement directly, something like what the Precision Gaze Mouse and similar software is doing. Would sure appreciate any further thoughts on this...
@@ErikServili On another note, I've found that the glasses work fine for general imagery. But while reading smaller text on the screen there seem to be random patches of areas where the text is blurred compared to other areas which are clear and well readable. I've done lots of testing and comparison to rule out eyesight problems and the issue does indeed seem to be in the device itself. Have you experienced something similar while reading small text through the device? The blurred areas will move and shift around the image as the glasses are shifted around my face or text is scrolled but there are always these patches where text is much less clear to read than in other areas where it is crystal clear. This makes the product itself look like not such a great choice for other than multi-media usage. Blurred text is not great for a desktop monitor replacement for regular work. I am wondering whether it could be just a faulty product or it's a general limitation of the technology.
Did you get anywhere with the steam plugin?
Nice review. Kind of pissed I bought my BT-35C last year for them to have the 40 with the 1080P display. I am also glad they killed off that Moverio market and going for more of a display headset rather than an all in one solution. That Intel android module was meh. Have you tried the 40S Controller? They said its android 9 so I assume it has the Play store? Does it support Google AR? Still an extra $500 up charge for what is an android phone seems a bit high
Well that took some digging but it uses the Snapdragon XR1? Holly crap why aren't they advertising that.
@@warlockd Hi warlock, I hadn't really looked at the android unit for the 40s, and honestly you're absolutely right, I don't think they put much advertising effort into it using a high end chipset. I've just been using my phone to drive the unit, and that has been a fairly good experience.
@@ErikServili Funny update, but my BT-35C port stopped working and I got a BT-35E as a replacement. There is a noticeable quality difference (better that is) too though it feels like they took the older BT-300 and just slaped on an HDMI adaptor to it. Still with the BT-45 comming out, still on the fence about swaping out.
Hey, thanks for the information. Do you know if the BT-40 works in a moving vehicle like a car?
Sure, there's nothing preventing that.
@@ErikServili Well, I tried it with the HoloLens 2 but because it's using 3D and room detection stuff it always thought, that me as a person was moving. So the holograms floated away.
That's why I am looking at more or less 2D glasses.
Thanks for the info!
can you put an usb hub between your phone and the bt 40 ?
wil it stil take things like a secondary webcam ? or annything ?
You could do something like that by using the wacom link, but no, as it stands nobody makes a cheap USB hub that can pass through DP to use it as-is. You could try a thunderbolt 4 dock by those are quite expensive.
@@ErikServili i mean when i read expensive and realized the glasses r expensive already i kinda realized nothings wrong with flying on your laptop screen
How does image quality compare with the BT-300? I am debating what to get for drone usage. Thanks!
The increased resolution is very noticeable and the image quality overall seems like a nice step up.
That said, keep in mind that all existing HD FPV transmission systems are at 720p, and camera colors are good but not amazing, so it's hard to say how pronounced the difference would be for your use case.
@@ErikServili hmm, thank you very much for your insight. Both very useful and conflicting, haha!
get a Dreamglass 4k!!!! Im so glad i got one.
Does the OLED on these have any issue of burn-in?
No idea. I haven't experienced any yet and generally I'm using it for active content so I don't expect burn in regardless.
hi erik , do u feel any eye strain after long hours of use like fatigue and stress on eyelids as the reflection is very near to eyes? pls reply.😊
Not really, but I could see it being a little straining if you had them pegged at max brightness for several hours. Generally I manually set a reasonable brightness, otherwise the auto brightness should also find a comfortable level for most lighting situations.
Thanks for the video. I tried to connect the BT-40 to my PC via a Wacom Link Plus but it does not work.
Hi, thanks for trying it out. Can you tell me if your computer detects anything at all when you plug the moverio into the link?
@@ErikServili Nothing is happening in the device manager
@@MrNillang Trying to get a hold of a Wacom Link unit to test, will report back once I do.
@@MrNillang There is a 1.0.1 firmware update available online. You can find update instructions online on epson's website. I would try that and test the link again.
@@ErikServili unfortunately there is no change. Maybe there is an issue with the link...
So I got these and I tried plugging them into my Thunderbolt 4 port (surface laptop studio i7) and it detects a second display but I can't get anything to show on them. Also on the epson website their screenshot shows "Epson HMD" while mines doesn't, any advice?
Do the glasses themselves display the Epson logo when plugged in? First step would be to download the firmware update for them and apply it, it improved compatibility with some PCs. Hopefully despite video not working, the updater will work fine, otherwise you may need to try another port or PC (might not need to be a display capable port, I don't recall).
@@Servili007 No they don't display the Epson logo when they're plugged in, and yes the updater works and I updated it to the latest version (1.0.1 to be exact).
@@Servili007 UPDATE: I just ran the updater again and apparently last time I ran it it only updated the MCU version, so I had to run it again and now it works!! THANK YOU SO MUCH!! :D
Hi thank you a lot for your videos. Can you confirm that any camera is present?
No, there's no camera. Its primarily a 'budget' personal media viewer that you could incorporate into other projects by adding additonal hardware like cameras. The built in cameras in previous models were low quality to the point of not being practical.
@@ErikServili thank you a lot
Hello, I was curious if you find it possible to write or edit documents using the glasses? I'm trying to find an option to write code lying down because I can't stay upright all day. Additionally, my disability makes it hard to turn my head so it would be awesome if the video was locked to my field of view which it looks like this item does. It seems like most cinema glasses have motion tracking built in and look kind of heavy which would be a problem, so this might be the best option if the display is clear enough. But you weren't kidding about the availability issue, all I could find was this for about $1,500 on eBay! Maybe you have an answer to this question; do you know of any other products that just displays hdmi/dp/pc output to set of glasses/goggles instead of a monitor? Thanks!
It's certainly doable on these, though I haven't tried to do it for hours at a time so I can't comment on strain. These are, as far as I'm aware, the highest quality units currently available. Others have lower resolution or odd form factors.
@@ErikServili Thanks for the response!
Hi Erik, new subscriber here! Was wondering if you knew why I get this annoying flashing White line at the top of the image in my BT-40 glasses when I use an HDMI to USB-C converter/adapter.
Hi f13dfx, glad I can finally see one of your comments, I got several notifications but they were always gone. Unfortunately, I don't have any insight into the white line issue. I'm looking to pick up a wacom link (which I believe you didn't have any success with?) and some other adapters to test, though converters are notoriously troublesome when converting to displayport. I'll update once I've had a chance to test them. Thanks.
@@ErikServili Yes, my comments kept getting deleted. Maybe you can pickup one of those rare HDMI to USB-C converter/adapters to see what’s creating that white line issue. I’ve tried Siig, Club3D & Goovis branded ones, all with the same issue :(
@@f13dfx There is a 1.0.1 firmware update available online. You can find update instructions online on epson's website. I would try that and test for the white line again.
Can I fly aa drone with this
Is there a google play store on these? If I create an app for glasses, can i just download it from google play?
Also, have you tried bt-300 or any other BT? I'm thinkng between bt-300 (quite old) and bt-40 to develop some apps however I can't find google play icon on any video recorder about those two.
For sure i need a camera for smart glasses to make hand gestures but I still am little scared that bt-300 might be overpriced and well outdated for today's standards. What are your thoughts?
These are displays for any usb c dp video device, they have no CPU or OS of their own. You'd publish to the play store and download it on your phone after integrating Epson's API. Owned the bt 300 and think this new approach is preferable as the bt300 hardware aged sooner and worse than the displays.
@@ErikServili Ooo okay, thanks a lot. That actually answers my question quite good.
@@ErikServili Oh Erik, do you think I could connect bluetooth camera to my android or PC and then see that camera by bt-40? So I can put camera on top of bt, connect it to phone and then it would be recognized by the phone. That means I can actually use external camera with bt-40, am I right? Or there are some limitations?
@@Drymarti the only limitation is your phone's capabilities, this device is just a display. You could technically do it over USB as well, but hubs that support usb c + dp input and also have a usb c dp output are not very common or cheap yet.
@@ErikServili Right, so it is just a display device. Okay, thanks a lot again!
Work with iPhones?
the concept of the product is quite innovative, and practical, yet it makes the user struggle alot to have a proper actual use for it.... But I'm very glad there was someone who takes more deep look in this device,
in spite of its broad possible usage, I think the device is used by only minor group. possibly due to its pricy entrance to have one of their model....
and compared to the technology they actually achieved, They do lack just one or two simple tricks which could actually have been critical element to drag in many demands.
ONE BIG heavy technology achieved, yet one or two bad spot ruining the whole picture.
That feels really, amazingly ridiculous. and extremely annoyingly silly !
and I don't know if Epson really knows how they do their work, but It feels even worse from the point of view of someone who purchasing their goods..
This is what I've experienced.... but still I am trying to find the proper usage for this with patience.
It's been about months for me using this device, my most recent interest was.... "possible methods to use this SmartGlass device as HDMI receiver?"
I've been trying to use this Epson Moverio Smartglass BT-30C device for multiple beneficial ways,
especially as it was advertised originally,
as its output connect is C type USB, and as connected to android phone,
it could successfully recognize Moverio glass as HDMI device, so enabling to mirror the screen of my phone.
major usage from this product seems to be related with ... streaming the vision of Drone flying.
in my personal usage from this product (Moverio BT-30C) is to firstly mirror my android phone's screen and then remote connect to my PC.
So eventually, as if using my PC, yet being free from the duty carrying around heavy and bothering big sized monitor screen. as I could use my Moverio glass as if monitor already ! which is Fantastic.
The method though, requires strong internet connection as it will do remote connect to my pc.
But then, here is my question in a bit different usage, perhaps more advanced.
So here I have STICK PC, which is a product maximizing portability, having a complete PC concept in a size of pocket, as simple STICK form.
and most of times it is meant to be used with a monitor that receives HDMI signal, as these STICK PC, have this male HDMI output connector. (and encoutering monitor device would have female HDMI port, which needs insertion of male output connector)
So here at this point,
I do personally think the most powerful benefit of BT-30C Moverio Smartglass is how it could be absolutely portable, pocket sized 'monitor' that you could literally wear !
and if only I can use this Moverio SmartGlass with my STICK PC,
both will be portable pocket sized, light weighted, pleasurably carriable anywhere.
Imagine a situation taking a flight from somewhere Tokyo, and to Lisbon, Portugal,
which will consume more than 12 hours in fixed seat during the flight.
only if Moverio Glass was something that was designed to be able to use even with HDMI port, maybe purchasing some of more supplementary tools,
I can really convert all those very boring and time wasting hours into sheer work-hours.
as I could do my work, even in environment that is offline non-internet connection.
and not even needing a desk in front of me to place a monitor. as I could simply wear this Moverio Glass on my eyes.
and maybe I can place my keyboard on my lap, therefore I can do my job as much as I want just freely. It sounds really fantastic,
It becomes really the moment in any physical environment or transportation you take such as BUS AIRPLANE TRAIN SUBWAY
or even sitting in the middle of park , in a street bench,
you can do your work. ANYWHERE.
and I'm keep trying to advance its usage to reach that point, which could really maximize the product (moverio glass) 's usage.
(This is the STICK PC I have btw. just for information let me tag the link so maybe you can acquire the information if needed...)
www.amazon.ca/Twingle-Stick-MDS-2300W10AC432-Compact-MicroSD/dp/B06XFXW2YX
after some of repeating words,
My eventual question is .... IF Moverio SmartGlass BT-30C was designed to be able to use with HDMI output male connector having device. (Just as the STICK PC product which I showed above.. )
even if originally it wasn't aiming that purpose,
if there could be any breakthrough method with supplementaries. ex) convertors etc.
I already have tried some of plausible methods by myself, yet it didn't really work unfortunately.
the method I tried was, purchasing these few supplementaries below.
(1). HDMI receiver (female) to C type (male) convertor.
(2). Female (C type) to Female (C type) connector.
So then, receive this hdmi output connector by (1) , and then connect it to (2), then receive C type connector from the both sides (STICK PC and Moverio Glass)
for some reason, it didn't work.
and for now, I am really lost which solution I can find in this situation.
Pret?
Does looking through the lenses optically distort what you are seeing? How about peripheral vision, is it noticeably reduced? I do a fair amount of biking and I don't mind looking like a geek. ;-) I'm thinking about investing in these, but I'm wondering how safe the experience might end up being? I'm less worried about road riding, but more concerned about riding singletrack trail.
I'm guessing I could not only get used to but eventually enjoy having a transparent heads up display of Google Maps or a rear view camera or texting (read and respond to short text messages by voice). I believe I could also get used to reduced peripheral vision and not having a glasses-free 100% undistorted field of view.
So maybe you can't speak directly to biking, but have you done things like gone for a short drive or going out for a hike with the BT-40 on while you were using it? For lack of a better phrase, do you feel the BT-40 "got in the way?"
If you had to take a guess, do you think it would be suitable for my intended uses?
Thanks for putting up your informative review, subscribed!
Bonus questions: would you guess using them outside in bright sunlight would wash out the image too much to be worth using? Would using them on an overcast day potentially increase visibility to the point of being usable? I'm not sure if those magnetic sunglasses Epson makes for these would be practical for how I envision using them, but if I found a large enough pair of regular sunglasses to modify, do you think that using those might increase the screen visibility especially on a bright sunny day?
You're only losing a little bit of the middle of your periphery due to the sides of the glasses being there. The area where the images project is slightly darker than the rest of the glasses and your vision, and there's a very amount of distortion right at the transition to that darker region, but nowhere else.
The glasses don't get in the way while walking/hiking and I have had maps operating, but no, I've never tried them while driving. There's a big warning not to use them with moving objects since the potential technically exists for whatever you have hooked up to them glitching out and projecting a solid color right in the middle of your vision. Realistically, since you can still see above and below the glasses, it's probably fine.
I think for your intended use case, you'd need a something holding the two arms together so the glasses can't slip off your head. I'm not certain how well they'd hold up to the repeated shocks of mountain biking, and the "sweet spot" of the screen may be a little hard to maintain while bumping around. At least that's my suspicion while using the standard nose rest. I'd say you may be able to make it work, but it's not an ideal use case.
Regarding bright sunlight, I think anything mimicking sunglasses in front of the screen would achieve the same effect as the magnetic ones and should allow you to use them. Otherwise, it can be a little hard to make out the screens while looking towards the sun (especially if the brightness isn't at max, which itself will drain more battery/make them run hotter)
@@ErikServili Awesome answer, thanks for taking the time to reply. There is a product called croakies that looks like it might serve well for keeping these glasses in place.
Maybe you haven't had them long enough or have used them enough to have enough material for a follow-up video, but I'd definitely like to see it if it happens.
Potential topics to discuss:
A) how often do they actually get used during a typical day?
B) what use cases (and/or apps, programs) did they actually get used for, as compared to what you expected you would use them for
C) are there things you use them for that surprised you?
D) are they used most often with a phone or a computer or something else?
E) I've heard someone talking about a competitor's product and saying that they were tiring on the eyes to use after an hour or two... I suspect you'd have needed to start using a wireless power bank to use it with a phone more than an hour or two... it would be interesting to hear if they are tiring on the eyes or feel too heavy to wear after X amount of time.
F) I'm thinking one of the coolest use cases would be watching immersive 360 degree video, especially the highest definition videos available on UA-cam. I think the glasses themselves have the right sensors to make that work, but I wonder if there are any moverio-friendly video viewing apps out there that even allow that? My guess is using some croakies with a horizontal phone pouch would allow a workable work-around for immersive 360 degree videos.
G) if you have worn them going to the store other places where people have seen you wearing them, what has been the reaction? I remember the word everyone used for Google Glass users back in the day, glassholes, lol. It's probably too bad that most people who might see you wearing this could assume there's a built-in camera when there isn't.
H) anyting you'd like to do with them in the future but haven't tried yet? For me, fpv flying would look like it'd be worth picking up if I end up with a pair of these. Watching at least one sbs 3D movie? I could think of at least a dozen other things, I hope I can fit these in my budget a lot sooner rather than later.
Well anyway there's another stupidly long post of mine, perhaps these are just mostly gathering dust for you by now and you are wondering what all my fuss is about, lol.
Given that it looks like hopping on a bike and taking a ride to the beach and getting outside in general looks to be a good idea with these, I think more people would be willing to give them a chance if they knew the capabilities.
I'm not sure how much work I could get done walking around the beach with these, but I know I would definitely want to make it work given how much I like the sound of that scenario.
@@ErikServili Sorry for the billion questions by the way (again, lol), but if you still have your BT-40 and maybe my last post inspires you in any way to make a follow-up video, all the better. It really looks like some promising tech, even though I've read recently it does tend to get pretty hot if it's used too long.
@@MichaelSTaylor Thanks for the questions, and no worries. I don't know if I'll do a video response, but I'll at least put together a reply soon. They do get a bit hot in extended use at high brightness, but I'm usually below half brightness since I'm indoors in areas that aren't overly bright.
I've had a plan to demonstrate my VR solution for them for months, but still haven't gotten around to it unfortunately.
@@ErikServili Yeah whenever you find the time to cobble together any kind of response to that inquisition of a post, that would be fantastic. I'm not sure what you have in mind VR-wise, but I think that would definitely be something to look forward to as well.
I wonder why they dont make a whole all in one pc in glasses setup with these. Just put smartphone internals on one side, battery on other, gesture controls on bottom and you have a pc in your glasses.
because there’s not enough space and also hard to cool down with such a compact setup
whats the battery life like?
It's powered by whatever you connect it to
@@ErikServili Which was really poor in my case. I returned my glasses a week ago because of how much of a power hog the glasses can be. I would only get about 1 - 1.5 hours of use from 95% to 5% battery on my Note20 Ultra. What also sucks is that you can't connect an external battery to the device (as far as I'm aware, the controller board has an unused push connector that is close to the USB PD chip.)
Hopefully the next generation of this device allows the ability to do PD charging to a battery pack, with that I'd be able to wear and use it all day.
@@AidanNaut0 I've been using a 15w (edit: actually it's a 10w) wireless samsung fast charging puck to make it more manageable while using my phone, but my phone has an odd behavior where the charging speed drops dramatically when USB is in use. I've been using it with an extension cord on my PC as well where draw is inconsequential, but I agree that a USB C input for power injection on the cable seems like it should've been a strong consideration given the power requirements.
I'm tempted to also try one of those phone sized battery banks that have wireless charging on board, but I don't know of an affordable one that does 15w charging.
Edit: I am surprised that you got similar run times to my S8 with an aged battery. Also, could you elaborate on what unused connector you're referring to?
@@ErikServili if you pop open the chassis that houses the audio jack, youll find that a whole board is in there, with a usb hub chip, pd chip, and mipi chip. There are two push connectors that connect to this board from both headset and usb end.
@@AidanNaut0 There are Phone cases with integrated batteries on the back which can do Wireless charging, search for them you could extend the usage by another hour
They are very cheap and discreet compared to Apple vision ,,pro” ,Aplle joke is apple playing on us for 3499$.. only downside of them not having iOS app they work only with flagship android w. Usb c display alt mode .you explained connectivity perfectly…

I was always under the assumption that the glasses would need to be close to my eyes for me to experience a large frame of content with readable text. But the doctor in this video wears the glasses a good distance from his eyes and appears to still be able to read text and utilize whatever content he is viewing.
ua-cam.com/video/QYoBmPOfZ8Q/v-deo.html
I was also planning on wearing these on top of my glasses. I think the bt40 would end up roughly the distance away from my face as the doctor has in the video.
You've had these glasses for a while but if you don't already know, could you take a second to just confirm whether or not the BT40 is usable if it is placed further from your eyes like in the doctor video?
Any additional commentary you might have as to the usability of the bt40 when it is normally closer to your eyes, or further away could be really useful, thanks.
The glasses are made to be worn at a distance that allows you to still wear corrective eyewear underneath while seeing the full screen. That said, if you take that to the extreme and wear them too far away, you start to lose the edges of the screen and clarity outside of the center starts to get worse. The video you linked doesn't really have the user reading text, just observing graphics, so they can get away with moving the glasses further from their face. Text font size and position would be a big factor in how far away the glasses can be while still being legible.
Bought them after seeing this video since Epson decided not to market these at all and nobody else is properly reviewing them. I wanted a decent 1080p display as a second (or primary) screen on the go for my GPD Win 3 and maybe my phone.
Sad to say not only do they not work with my Android device (Pixel 4a), but they don't work with the primary device I purchased them for. A friend came across an Intel post alleging they don't work AT ALL on ANY Intel Xe device, which seems insane to me because that means all recent Intel devices just don't function with these.
After contacting Epson, they took a few days to get back to me just to offer me a return & refund. They have no intention of properly supporting this device. 🤦
Sorry they didn't work out for you. Google decided to push their cast ecosystem and not include USB video output on any pixel devices, so that part is on them. As far as the Intel support issue, can you link to the post your friend found? If it affects the entire Tiger Lake series (which I agree sounds crazy), I'd be interested to find out if it's on Epson or Intel trying to wiggle around the USB C DP spec, though info will probably be limited if I can't get my hands on one of their engineers.
@@ErikServili I went back and tried something I should have tried on day 1, assuming it just wouldn't work... I was able to just dump the configuration from a working machine using CRU, and then importing it on an Intel Xe machine... that was all it took! Working flawlessly now.
Thinking of putting pinhole spy cam in shoe and connect it to the camera.

They feel CLOSE ENOUGH to sci-fi visors but not entirely I am up to debate on buying them in 2023 to watch streaming and they're available on the market compared to discontinued products like the Royole Moon and Sony HMD they look more futuristic is why I want to try. Yeah definitely doesn't get the Google Glass type feeling to them at all this is technology probably being adopted by the military as well or the government the screen is kind of small but certain tasks like translating might be a kind of sci-fi type feeling. The screen is very debatable and probably not worth the money these people are asking for I'd be kind of cautious about it it's not bad but if you're expecting to look futuristic find something else that screen display is kind of small.
