Monocular head mounted display. I've got my beady eye on you.............................................................................................................

In 2009 I posted an Instructable on how to make a pair of glasses with a head up display to one eye, using a pair of Olympus Eye-Trek video glasses.
http://www.instructables.com/id/Glasses-mounted-v...

My reason for these projects is that I believe wearable displays will become very useful in hospital medicine, particularly anesthesiology.

UPDATE June 2014: Updated much smaller more compact version due very soon with 3D printed shell.

Since then there has been a lot of interest recently due to the current Google Glass project, which puts a head up display in front of one eye in a very neat package resembling a pair of glasses with nose-piece, top frame across over eyes, but no lenses or lens-frames.

Funnily enough monocular displays are much more expensive than binocular ones despite only having the one display as they are perceived as semi-professional devices. The military use rugged versions and also there is a big push to bring them into medical applications.

This is my attempt to make a much better version than last time, somewhat inspired by the Steve Mann Eye-Tap project and also inspired by Martin Magni who has previously hacked the video glasses I intended to use. Specifically the aims this time are:

a) Not built into a pair of glasses. Instead we have a nose-bridge to locate one end, then a springy strap runs around the back of the head to a small pad under the ear on opposite side. This arrangement is inspired by a recent concept version of the Eye-Tap (which also originally used a glasses type frame).
b) Several DIY projects out there hack a display from one side of a pair of video glasses then mount it in an arm on a glasses frame in some way, often with a lot of experimentation required to get the correct alignment with the eye. In this project, I simply keep the factory alignment of one side of the video glasses I have used.
c) As small as possible: Most video glasses blot out all forward view and light entering from above and below. I want the exact opposite, I want to wear these while doing other things, so I want to see with one eye, and with the "video" eye also be able to see in stereo if I look up or down.

Although the display looks very close to my eye, I can easily see what I am doing in stereo if I look down normally (not all the way down, just glance downwards is enough). This is the advantage of the very slim display.

Many video glasses because they are wide and block out light, can tend to have a flat circuit board running the full width of the part in front of the face. This makes hacking them to make a one-eye display not impossible but tricky.
The Myvu-Crystal glasses are great as they are essentially two displays, with a separate cable to each side, linked in centre over the nose. The quality is pretty good and yet each display is physically very small.

I have a 3D printer and original plan was to remove the electronics of the display units and embed one in a printed structure over my eye. However the more I thought about it, the more I realised that the Myvu-Crystal eyepieces look pretty good anyway, and certainly better than anything I could design and print.

The springy band around the back of the head is actually from a gaming headset which comes with a springy band with a pad on the end, a single headphone, and a small boom microphone.

With some hacking I joined the two together and made a really neat very comfortable minimalist monocular head mounted display.

Also, it comes with an i-Phone / i-Pad / i-PodTouch connector so I can download movies or TV programmes from for example BBC iPlayer, onto an i-PodTouch in my pocket and watch them on the move. If they come out with any decent augmented reality apps in the future, I can use them. Otherwise I will stick to watching films and TV.

Obviously this also might interest the wearable computing community too. Took about 3 hours to do which is vastly less than my first attempt in 2009.

What you need:

Myvu Crystal video glasses or something similar ideally with an iPodTouch / iPad type connection option:
http://www.engadget.com/2009/04/24/myvu-crystal-r...

A basic gaming headset, the sort with only one headphone on one side and a pad on the other side.
http://www.amazon.co.uk/dp/B000GET9P2/?tag=hydra0...

Dremel with a cutting disk or something similar.

Epoxy glue or a glue gun.

Optionally a very small nut and bolt

Step 1: Google glasses and Steve Mann Eye-Tap

Picture of Google glasses and Steve Mann Eye-Tap
I have to credit Steve Mann here of the eye-tap project, see upper part of the image:

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

Also, Google are working on the Google-Glass project (lower part of the image).

I did not really want to use a spectacles frame or pair of safety glasses this time around to mount the display. I found inspiration for a way to do this from an image linked to the eye-tap project..........see next page...............

Step 2: Inspiration for this project

Picture of Inspiration for this project
This is a lot more like it. These images are concepts for the eye-tap.

We use the nose bridge to keep one end stable, then have a springy band arrangement around back of the head to secure other end. The outer side of the display mount runs over the ear on that side, giving another fixed anchor point.

It just might work, so now I needed a really small pair of video glasses, ideally a pair with separate cable to each display, and one that does NOT have a circuit board that runs across in front of the face of the user.

There is a pair of video glasses that fit this description: The Myvu Crystal.
Note, they make other models but this is the one I wanted.


Step 3: Step 1: Find a pair of, ideally, Myvu Crystal video glasses

Picture of Step 1: Find a pair of, ideally, Myvu Crystal video glasses
Here are the Myvu Crystals. You have to search around for them. Mine were from the US.

They also come in black but I quite like the amber look.

See how slim they are. See how no electronics crosses over the nose-bridge. Ideal for what I want to do.

Step 4: Step 2: Obtain a gaming headset / microphone with just one earphone.

Picture of Step 2: Obtain a gaming headset / microphone with just one earphone.
Any cheapo gaming headset of similar design will do. Try to get one where the shape of the side with the headphone on is wide and flattish (or could be made flat) as we are going to embed the arm of one side of the video glasses into it. Black is also best colour so matches side arm of the video glasses.


Step 5: Step 3: Cut off the ear rest

Picture of Step 3: Cut off the ear rest
I use an abrasive cutting disc in a Dremel for all these sorts of jobs.

Cut off the arm of the video glasses on the side you want to use, about 1cm BEHIND where all the cables come in bringing the video (too far forward and you cut all the cables and ruin it).

Step 6: Step 4: Remove mic and earphone from gaming headset

Picture of Step 4: Remove mic and earphone from gaming headset
Again, using gentle force, dremel etc, remove the earpiece from the gaming headset and also remove the little boom microphone. Remove all wires. We only want to keep the springy band which will go behind the head.

Step 7: Step 5: Hollow out end of the gaming headset to take eyepiece

Picture of Step 5: Hollow out end of the gaming headset to take eyepiece
We now want to make a groove or socket into which we will glue/bolt the shortened end of the side arm of the video glasses.

Carve away gently and try to get the shapes to match so one will neatly fit the other.

Step 8: Step 6: Hollow out end of gaming headset

Picture of Step 6: Hollow out end of gaming headset
Looks neat from a distance, messier close up.

Step 9: Step 7: Test fit the two main parts, tape together.

Picture of Step 7: Test fit the two main parts, tape together.
Here I have temporarily taped the two parts together so can measure it up on my head and see if it fits or not, whether too tight, too loose and so on.

Step 10: Step 8: Test fitting of two main parts

Picture of Step 8: Test fitting of two main parts
Test fitting the cut end of the arm of the video glasses into recess I have carved in side of the gaming headset springy headband.

Step 11: Step 9: Side view of two parts taped together

Picture of Step 9: Side view of two parts taped together
Looks OK. Note how headband will not go over my head but actually around behind it. The pad I want to end up below and just behind my other ear.

Note how from the side everything is in same horizontal plane. This is not quite how you need it.

Step 12: Step 10: Get correct angle before gluing everything together

Picture of Step 10: Get correct angle before gluing everything together
Here I have rotated the two parts at the point where the end of the arm of the video glasses and the recess I carved in the end of the headband meet, until I obtained the correct angle. See now how when the display is level and horizontal in front of my face, the pad on end of the springy headband will be under and behind my ear on opposite side. 

For me this seemed to work best. Probably depends to some extent on shape of your own head so experiment using tape first before you glue anything together!

Step 13: Step 11: Cut the nose bridge

Picture of Step 11: Cut the nose bridge
Cut the nose bridge.

Be careful to cut the correct side!
We want to keep the nose support.

If you cut it in centre the metal clip that holds the nose support to the amber frame will disintegrate so cut just to the far side of this metal structure.

Step 14: Step 12: Cut nose bridge at an angle

Picture of Step 12: Cut nose bridge at an angle
I tried to make the angle of my cut match the angle of the metal clip that the nose supports are mounted to.

The amber plastic is actually really tough so be careful cutting it. Take it slowly.

Step 15: Step 13: Cut off the ear bud

Picture of Step 13: Cut off the ear bud
Cut off the ear bud.

The sound through the ear buds on the Myvu is not great. If you put even a really cheap pair of earbuds directly into the headphone socket of the iPodTouch, the sound will still be miles better. We do not have the earbud on other side anyway. I want to keep stereo sound so I opted to use separate earbuds in the headphone socket of the iPodTouch.

Step 16: Step 14: Inside connection plug

Picture of Step 14: Inside connection plug
Martin Magni hacked some Myvu Crystals for his wearable computing project here:

http://www.martinmagni.com/blog/cyborg/

He cut all the wires to the unused video display inside the plug that goes into the little control box that comes with the Myvu Crystals.

I chickened out as was worried some of the cut ends might short out against each other and damage the whole thing.

Step 17: Step 15: Cut wires to eyepiece you do not want to use.

Picture of Step 15: Cut wires to eyepiece you do not want to use.
So, I decided to leave some cable hang out and cut it there.

I cut all the ends as far as I could to different lengths so less likely to touch each other. Also used v sharp scissors so no wire fragments hanging out of the ends of each cut wire.

Carefully taped them up.

Also means if the left display breaks one day, I could resurrect the cut right hand display, although the soldering would be a bit of nightmare on all these tiny wires, probably just about possible though.

Step 18: Step 16: All ready for final glue

Picture of Step 16: All ready for final glue
Here we are. When happy with the fit to your head, check the screen is in the right place for your eye. If sure you have everything right then glue two parts together.

Note, if you push the display right up close to your eye, you can still see it and focus "long range" on it just fine. Problem then is your eyelashes hit it when you blink! Need to get it just right for you.

Also put a very small bolt through where the 2 parts of the frame are joined, BEHIND the point where the cable comes in carrying the video etc. You do not want to drill through this cable during a momentary lapse of concentration.

Step 19: Step 17: All connected up and working

Picture of Step 17: All connected up and working
This is the general setup with an iPodTouch.

The iPod goes in left hand trouser pocket.
The small box for the Myvu is actually very light but hangs at level of my waist. Does not quite reach my pocket so needs a belt clip made for it ideally.

Step 20: Attempt to show view into lens

Picture of Attempt to show view into lens
Here is an attempt to show the display, almost impossible to get it into focus however.

Step 21: More on the gaming headset I used

Picture of More on the gaming headset I used
This is the gaming headset I used. Only chose this one as was low price, the side of it was vaguely flat and could be cut/dremelled to make a kind of socket to take the shortened side arm of the Myvu display.

Step 22: Rear view on my head

Picture of Rear view on my head
You can see here how cable runs over left ear and down. The springy band runs across back of my head and the pad sits just under and behind my right ear.

Later on I found some black ear buds with a longer than usual cable and very carefully and neatly ran each side across the frame and headband, then wrapped the cable around the cable of the myvu so still just one single cable down to left jeans pocket.

This may be completely out of your area of knowledge, but I can see that you clearly are very interested in these things. I'm trying to create a HUD for delivering a very small amount data. To be exact, a 4 digit number. Therefore, deconstructing a commercial device is a bit silly for me. I have my 4 digits of data being displayed on a 7 segment bubble display powered by 3.3v Arduino. The problem I have is that I cannot focus on this display any closer than 300mm from my eye. I need to mount it at about 85mm. I'm trying to decide what kind of lens or prism to use and where to source it. Any ideas?

I want to fly FPV model using "Dynamic Video Glasses" that are powered from a 30 pin Apple plug. Unfortunately I have an IPad min that uses a lightning connector.

Is there any way to drive these glasses (Mini USB) from RCA phono plug jacks so I can switch inputs between my IPad and a composite video downlink?

Right now the only way the glasses work is when I plug the 30 pin connector into an old IPad. I have bought every connector and adapter I could find, but nothing works.

I am guessing it is the power lead that is missing.

im not sure if anyone has mentioned but, couldnt you use the spy gear camera glasses for the camera feature. Dissasemble the video glasses and place it on the camera glasses?
donfrench1 year ago
This is nice but I want something a bit different and maybe someone reading this knows if it already exists. I watch streaming movies while I use the treadmill and stationary bike at the gym and would like a way to mount my cell phone so that it is about 12 inches in front of my eyes. It would be nice if the phone could flip up but if it is mounted a couple inches off-center that might work too. Does this exist or do I have to design one of my own?

I knew I had seen a baseball cap with a mega-brim. The Thompson Twins from the 80's.!

Nearly 12 inches in front of your face.

I think there is an Apple patent filed for a baseball cap with a clip for your iphone on the brim, although the brim does not stick out as far as you require!

Isn't this bad for your eyes? (Really, how can it NOT be?)
XenonJohn (author)  acuchetto1 year ago
Your brain adapts after a while and you start to see everything normally around you with the video image overlaid on one part of your left eye view. The brain is an amazing thing that adapts to the world around it, think of that experiment where volunteers wore glasses all the time for 2 weeks that inverted the image to both eyes. After a while they could walk around and do things normally as before.....until they took them off at the end of the experiment.
The eyepiece is set to "far" focus so you do not have to keeping looking close up and then far away, just far away all the time. Therefore probably not as bad for your eyes as you might think.

I noticed in your last hmd you said you had a camera hooked up to this I was wondering if this mod had a camera also and can would it be able to work with a smaller camera like the kind you find in those spy pen? I want to make one of these for soldering for some reason and I want to put a zooming camera on it..
XenonJohn (author)  CD_tatro1 year ago
The Myvu comes with several input leads including the white/red/yellow ones where the yellow plug is the video in and the white/red are R/L audio. This works with security cameras. I used a really cheap wireless security camera last time, a modern wired one that has a cable with a yellow plug on the end should work. I like the idea of a "solder-cam" it might be better than one of those magnifying glass-lamps I currently use.

Hi XenonJohn

By plugin wrongly the polarity into the pendant of Myvu, i burnt a regilator on the motherboard.
here are the photos showing the burnt regulator :

http://soktha.free.fr/tmp/_MG_7069.TIF

And according to what you see, do you think it is fixable?
If so, in order to remplace it, could tell me which is the value of this component.

Thanks very much in advance.

Soktha
XenonJohn (author)  confi1 year ago
This looks difficult to fix, though maybe not impossible. Other components may also be damaged. Sorry to be rather pessimistic.

techno guy1 year ago
that's cool, do you think this could be incorporated into a daft punk helmet so that it could also be a really cool looking heads up display? Also would it be possible to use this on a laptop instead of an ipod or iphone?
XenonJohn (author)  techno guy1 year ago
Yes probably.

They come with lots of leads including a simple RCA set with the yellow (video) red(R audio) and white(L audio) plugs for DVD players etc. If your laptop has yellow video out socket (some older laptops did have them) you could do it, else might have to buy an adapter. If you surf the web there are people who have connected video glasses to the raspberry Pi for example. The wearable computing community also have lots of knowledge of what works and does not work.
Where can one find this "wearable computing community?"
XenonJohn (author)  vader4061 year ago
I tend to use Google myself:

http://www.meetup.com/wearable/
Raspberry Pi supports output from hdmi, and I think input from usb as well, just disassemble a webcam and mount it to the helmet somewhere to get a realtime viewfeed, run it into the Pi, write a simple code to make your hud (people have done projects like this already, so you could edit their work) and then output to the video glasses. You may be able to get cool things like rotating minimap or live music visualizer that responds to the music around you, since the Pi can run debian!
I think arduino can output to hdmi, but to get input from the webcam and then output to the glasses would require stacking multiple shields or assembling your own, and that would be difficult.

Very cool, now you need to design a voice controlled app that does what google glass can, or at least close.
I would use Siri.
Dr. dB1 year ago
Nice!

Did you ever see the 1994 TV series "Earth 2"? (...GREAT show, somewhat-short-lived - only 21 or 22 episodes ...starred Deb Farentino, Clancy Brown and the ever-stunning Rebecca Gayheart...) This 'ible and others is/are getting very close to that show's audio/visual communications props (...simply referred to as "Gear" in the script...).

About as close to telepathy as (externally-mounted) technology is likely to get!
donfrench1 year ago
A baseball hat is a nice solution. I was thinking about something more like glasses. I wanted the longer distance because that is where my eyes focus without glasses but I might manage if I wear my glasses while I work out. I might just try making something.
XenonJohn (author)  donfrench1 year ago
Here is a clip to hold an iPhone to your baeball cap. Of course with this sort of thing you have to focus your eyes to "near" whereas all the video glasses have an optical trick that means although right next to your eyes, you use "far" focus to view them which is a lot less stressful on your eyes.

Nice job congratulations I wish you to innovate more project like this
Jailbreak and you can have video out for all iOS apps, not just ones that support video playback: http://planet-iphones.com/cydia/id/com.tvout2.tvout2tuner

would you sell a pair? i dont have the resources and equipment to do it myself :(
Would it really be a "pair"?

I'll just check my junk drawer for a pair of Myvu Crystal Video Glasses. Wait a minute, here they are. Check!
XenonJohn (author)  godsdog1 year ago
Well, a pair of Google Glasses will set you back $1500, you need to live in the US, you will have to explain what development work you will be doing with them in order for them to bestow a pair upon you.
So, for me, easier to spend $200 on -bay. Cheaper video glasses are available for about $80.

I did say you will have to work to get hold of a pair. Not all Instructables are built from junk.
great project
lolaser1 year ago
hi, really nice idea i have been wanting to make one of these for a while but cannot find the MYVU crystal eyewear unit, that you are using in this Instructable where did you get yours from, and do you know any online sites which still sell these and at a low price of anything from $0-80

thanks :)
Lolaser - Avoid the MyVu if you can... I used one for my instructable...
http://www.instructables.com/id/Raspberry-Pi-wearable-computer/
... and found the optics to be horrible.
XenonJohn - Nice job :) I like the method you've used to support the monocle.
XenonJohn (author)  Beenay251 year ago
I am biased as I only have the experience of the old Olympus Eye-Treks I used before in 2009 to judge the MyVu's by. Seem fine to me for watching video. If trying to view text as a wearable computer then I agree the resolution might not be good enough though.

Resolution certainly much better than the much cheaper myvu solos.

Has anyone ever taken apart a cheap Chinese pair of $80 video glasses, the type that look like wearing a headband in front of your eyes? Lots of these on the web. That would be the cheaper way to do it, so long as the contents of the enclosure allow easy removal of one of the displays.

Hadn't thought of calling it a monocle but suppose you are right, it is.

Just wondering if would be possible print a Borg style enclosure shaped to fit your face exactly (maybe use 123d program and photos of your own face to create a 3D CAD of your face) and make it self-adhesive around your eye, no support frame at all! That would be cool.
XenonJohn (author)  lolaser1 year ago
I really had to search hard to find a pair. The radio controlled aircraft community seem to buy up all second hand decent video glasses so they can fly their planes by webcam in the cockpit.
There are a pair of crystals on ebay right now but 15 people watching already. Probably all RC enthusiasts!

If you search under "myvu" as keyword you can see they still sell the solo-plus which is cheaper but also in extremely slim frame. However they have lower resolution than crystals have the "headband" style and I am not sure how the internals are laid out. However the controller box looks exactly the same as on my crystals so it may well be that there are just 2 displays and little else in the head display, which means you could modify them quite easily................anyone out there know for sure?

There is also this one by myvu on ebay which seems to have 2 cables to it, one for each side. Although frame design shields the eyes from stray light I bet if you took them apart the two displays might well be the same as in the myvu crystals, one on the end of each cable. Would be a lot of money to spend if I was wrong about that though.
