Epson Moverio BT-40 Smart Glasses Unboxing

Epson Moverio BT-40 Smart Glasses Unboxing
Slight correction, the headgear is most similar to the BT-30C.
Aside from SDK control, the Moverio Link app also lets you adjust settings from your phone.

Does the box come with the extended nose pads for wearing over glasses?

[@timothystiles3314]

Hi Erik, Have you tried reading with these? I'm considering using the bt-40 as a work monitor but I saw a review elsewhere where the reviewer said they struggled to read anything without experiencing double vision.

[@Servili007]

I mentioned in my other video on them that I was reading my video notes directly on the glasses. Obviously text size is very important and will ultimately decide whether or not you'll be able to focus and read, but I personally haven't had issues at the typical text sizes I deal with. The only exception to this (which may just be due to the fixed IPD and my own IPD being a little wide) is for text in the very corner of the display, but that's not a frequent issue. It is also possible that if you need vision correction, you may need to wear it while using the BT40

Pity it doesn't have camera

[@kevinmccrudden5699]

It's my understanding that it's just a USB-C powered display right? Should be plug and play with a PC?

[@ErikServili]

It's not like USB screens that handle their own graphics processing (and are often kind of slow as a result). It requires a usb C port capable of displayport alt mode, which rules out most PC ports, particularly on desktops. Thunderbolt connections also work since it's a superset of the capabilities needed. It's possible to use adapter cards like the upd2018 or something like the Wacom Link Plus as an input adapter if necessary though.

[@kevinmccrudden5699]

@@ErikServili That would make sense, seeing as there is no onboard video processing. Thanks for the reply, looking forward for the review of it. I will be attempting to purchase one when they happen to be available again.

when they increase the FOV to around 45-53 degrees - i will jump in and order then ! nice video

[@mad9704]

THESE ARE SO COOL

[@michelbisson6645]

I don t know AR that much more used to VR and oculus things, so does this device can run any AR app,can it run VR to? i ordered this from amezon should have july 16th they say

[@ErikServili]

I did develop an opentrack plugin to use this as a VR device on a PC, but I havent made a video about it yet and haven't released the code. Keep in mind that the FOV is much smaller than a typical VR headset and tracking needs to be adjusted occasionally. Also consider that this isn't like a hololens. It doesn't natively do AR unless you develop a solution with some extra hardware yourself. Out of the box, its primarily a personal video viewer that has some sensors to exploit if you download or write applications to talk to it.

[@adriankanis8107]

Nice ! Can I ask where I can buy this moverio? Thank you

[@ErikServili]

You can sign up for an in stock notification on Epson's website. Unfortunately it seems like availability is limited.

[@adriankanis8107]

@@ErikServili thank you!

[@er.nilotpalbiswas2897]

Does it only mirror the device? If I develop an app for object recognition will it simply use the camera from the glasses and simply show the mirror of my phone?

[@ErikServili]

The BT40 doesn't have its own camera, only 3DOF tracking, and primarily runs through mirroring. It's not something that competes with AR glasses, which sounds like what you'd want.

[@er.nilotpalbiswas2897]

@@ErikServili oh I see. I am just wondering about its use cases

[@markosimo76]

Hi Erik thank you for the useful video! Can you confirm that there is no camera? I can't understand that lack :-/

[@Ignotus.]

If you can see through, why would you need a camera?

[@rouder9237]

Hi man, can the trancperancy be adjusted, I would like to use such glasses for Google Maps while riding my Electric Unicycle, also is there an option to reduce the screen size or shift the position ? or even turn off 1 of the displays?

[@ErikServili]

Yes, the brightness directly correlates to the transparency. There are also SDK features to reduce the size but I don't recall anything about shifting it around directly from the SDK. Neither size nor shifting is built directly into the Moverio Link app though. You can't turn off only one display directly but you could enter 3D mode and not render on the side you want turned off (again, this isn't built into Moverio Link, you'd have to make it yourself). Actually, thinking about it for a moment, if your phone supports multi-app/multi-window mode, you can probably set that up to achieve the result you want without writing an app.

[@andrewferguson6901]

There's a guy who made a video about turning this into a one eye device with a chip mod. It's actually a really trivial bypass of the thermal safety circuit and you can just disconnect the other side no problem. Not exactly reversible though, so commit to the monocle I guess

[@farestabs]

Hey Erik, thanks for the video! I was wondering if the device had a microphone built in or how an AR application that would incorporate audio would look like...

[@ErikServili]

Hi, there isn't an inbuilt microphone, and I don't know if the audio jack supports microphones. You'd be using a microphone attached to whatever device you have driving the glasses, that being a phone or laptop or single board computer solution.

[@dennishedrick5308]

Thanks for sharing

[@husky9088]

Usbc??

[@martinkulik9466]

What is the practical usage of this? It would be more useful with ar camera with real time navigation, etc

[@ErikServili]

For most people it is just a 1080p personal viewer. It does have an IMU and Epson provides Unity samples for integration as more of an AR device. Since it has no processing power of its own it relies on the attached device. I'd say that providing an on board camera would've increased the complexity and cost and would've required software support that likely would have fallen short. What you're looking for is more akin to the BT-35E, but really at that point you may want to consider a hololens for proper AR tracking.

[@martinkulik9466]

@@ErikServili ok but are you actually going to use it for which situation ? Lying on bed and as a projector? Resolution is good? Will you make video about it and how you use it?

[@ErikServili]

@@martinkulik9466 I may make a video soon. Yes, the resolution, contrast, and colors are extremely good. Epson has a lot of experience and market share in projectors, and it shows in this device, unlike its competitors. The last few days I have used it mostly for youtube and game emulators in retroarch.

Will the BT-35 /300 sun shield fir the BT-40?

I don't think so, but I'm not certain.
