This is a project which will literally pull your mind out from your head. 

The whole idea is to view ourselves live in 3rd person. A camera will be mounted to ourselves looking at us from behind. A video goggle setup will then allow us to only see ourselves in 3rd person.

We will explore how to make a setup like this for relatively cheap. We'll look at other permutations, such as transmitting the data, using the setup in paintball with a marker mounted camera, and so on.

[edit: check out step 10 for the 3rd person view]

Step 1: The Camera's

As the setup goes, really any camera with a video output will do. I have a small video CCD camera with the component video and audio output. That ran me about $60. You can get cheaper ones if you'd like. If you really want to play with this, I would suggest getting a good camera. After having done it, I would prefer a higher quality camera. 

Some digital cameras or camcorders can do video out as well. That will work, as long as it is live.

Step 2: The Video Goggles

This is the more expensive part. There are a few options out there when looking for video goggles. I have a headplay setup. It gives me a 800x600 resolution, which is one of the better ones I have seen. These run around $350. You can get some 520x480 res googles for $250 if you look. I have other projects in mind for these goggles, so I wanted something better, but it is expensive.

We did look at other options, but to really immerse yourself into the video, a goggle setup is best. Further more, in the future, if I can get some 3d cameras, the goggles I have will support that.

It is possible to get a small LCD and stick it in front of your face, but that just doesn't seem that it will work as well. And when you consider that a nice sized screen will run you $100 to $200 bucks, plus you need a way to mount it, it just doesn't add up.

Step 3: Radio Transmisson

This part is entirely optional. We placed a video splitter on the camera and ran it to a 800mW 900Mhz radio transmitter. Now, a word of caution. You do need an Amateur Radio License to legally operate something of this power. It is true that you can buy them anyways, but it is good to stay legal. The nice thing is, it is easy to get your license. 

The information needed to get your license is located here:



Step 4: Recording the Video Stream

We have the radio setup transmitting the video and audio. At the other end we have the receiver which is connected to the video -> USB converter. This allows a remote viewer to watch what the camera is seeing. It also allowed us to easily record the video stream.

I am using a KWorld converter. They are cheap, it seems to work well. There are a ton of other options.

Step 5: Constructing the Camera Mount

The camera mount system is made of 1/2" PVC. A frame is constructed and attached to a vest. If you don't have a vest, no worries. I just had one around. You can easily strap the frame to your chest with some straps. This may actually be better as it will hold the frame more closely to your back, whereas the vest had some play.

Extending from the frame is a T junction with the boom. The boom need more support so initially we added some string, and then some wire, but finally we decided we needed some more rigid support and added more PVC pipe.

Only the T-junction at the base of the boom was glued in. All the rest of the pieces are hand tightened.

It is important that the whole frame is rigid and well attached to your body. As we will see later, the motion of the camera relative to your body can make or break the experience.

The camera itself was attached by screwing the mount that the camera came in into a PVC cap. This work very well and it allowed us to adjust the camera angle which was very important.

Later we used some digital cameras to record the action at a higher res. Because the cap was just fit on, with no gluing, we were able to switch it out for a cap with a 1/4-20" bolt which screws into the standard camera mount. We cut a slot into the cap so that the camera viewing angle was adjustable. With the boom fixed it is important to be change the camera angle so that you can see yourself. Also, with different people wearing the suit, we needed to sometimes change that angle based on their height and preference.

Step 6: Gimbals Mount & Other Failings

Initially we were dead set on building a gimbals system in order to stabilize the camera. There are a ton of instructables on gimbals, and we more or less followed their ideas. 

We found in the end, that the gimbals did not reduce the motion. We wanted to dampen out the jostling motion of walking or running. However, the wobble of the camera in the setup was far too disorienting. Finally, after testing a camera fixed to the boom we decided that it was really not all that bad and we stuck with it. 

After walking and jogging we soon learned the value of having a rigid frame and made adjustments there as well. Any wobbling or jostling of the camera was very disorienting.

Step 7: System

So, now as we have discussed all the parts, we need to put it all together. Really, it is simple. The camera output goes to the goggles and the radio transmitter. The radio receiver is connected to the USB converter.

The goggles have their own battery, the camera and transmitter work of 12V. We tried two different power sources. The simple, yet more expensive in the long run, method was to use to lantern batteries in series. This provided the 12 volts needed. The second option was to use a 11.1 V lithium battery. The equipment worked fine at this voltage and the battery was substantially smaller, lighter, and rechargeable.

Step 8: In Practice: Testing

After getting the whole setup working we did some tests just standing. We didn't yet have the batteries hooked up, so we were tethered in a sense. This allowed us to test the camera and goggles and gimbel to get our initial reactions.

First reactions: It worked well. It felt very odd and I can already sense the effect of a moving point of consciousness (we'll talk more about that later) the gimbel is working, but needs some adjustment.

Step 9: In Practice: Walking & Running

Second Tests:
After getting the battery connected we were able to walk up and down the hallway. Right away the gimbel was a problem. It was swaying far too much. Were able to make it better by changing the mass and adding some damping, but in the end we settled on a fixed camera. It was hard enough to walk around in this thing. With the camera moving, it made you feel sea sick.

Depth perception is an issue. It is also hard to remember that you have this thing strapped to your back, so no quick turns indoors and everyone else needs to watch out.

Step 10: In Practice: Depth Perception

Outside Tests:
Now we took the setup outside where we had some room to run. Objects look farther away than they really are. This is due to the wide angle lens on the camera. 

We were able to cautiously run, but after 5 minutes in the suit you started to feel comfortable. Because you only have one camera, you lose a lot of your depth perception. But that is not the only way we sense depth, and soon my senses we adapting. It is amazing what the brain can do. 

Looking back upon the tests I remember being 'sucked' into the camera. I felt like "I" was the camera. It was odd. I felt taller. In fact, because you were at a different level than the camera, it was easy to get your dynamics messed up, and sometimes we almost fell over.

After wearing the setup for a while and removing the goggles there is an odd feeling of your point of reference being adjusted. As if your consciousness were being sucked back into your head. Wild stuff.

Step 11: Advanced Setups: Multiple Cameras & Gun Mount

After ripping our minds out, we decided to play around with some other options. There are a bunch of ideas here, but we decided to stick with the video game type views. We added a camera mount over the shoulder, to give that 1st person iron sight look. And a gun (paintball marker) mounted camera.

We recorded the video separately on the two cameras on the back. We transmitted the marker mounted camera signal to the laptop where it was recorded. The goggles viewed the marker camera. In the future we will add a switch so that you can quickly switch between views. I am sure that will mess with our heads even further.

The paintball mounted camera worked very well. It was very natural and a nice break from the 3rd person view. Being able to control the camera position manually helped a lot. The basic idea here is that using a setup like this, you are able to stick your gun out and scout out an area and possible fire at a target without putting yourself in danger.

Of course, running around with video goggles on is sure to get yourself killed, but heck, this is just a test.

In practice you are more likely going to use a separate video screen or heads up display for the gun camera. This allows you to see naturally, with the option of viewing the gun camera. This is in the works.

Either way, it was a neat experience to use the marker mounted camera. It was a little dark out, and with the resolution of the camera it was hard to see the target (a cardboard box) and the paintballs clearly. However, I was certainly able to scout around safely and make decent shots at the target.

Given daylight and a larger target, it would have worked better. Either way, it was an worthwhile experiment.


Step 12: Future Work & Ideas

3D Cameras
We'd really like the use a 3d camera. This will either require a 3d camera setup, or an additional camera and a way to interlace the two views as this is the format most 3d capable googles read the video in. Otherwise, if we can find some video goggles that can take in two video sources, that would be easiest.

Remote Control People
The original purpose of the radio transmitter was for another idea which hasn't been implemented yet. A human subject would wear the 3rd person camera and no goggles with their eyes covered. The video signal is transmitted to the controller. Using remote controls or some other signal, the subject would move according to the controllers wishes, much like a video game. 

Move the 3rd person camera back
The 3rd person view we used was pretty close. It was challenging not being able to see your feet. Also, in a lot of 3rd person video games, you can see the entire character. This is difficult to do using our method as it will require a long extension rod. Also, you will be able to see the camera mount in the camera. We are experimenting with some ideas around this such as using a balloon.

Camera Movement
It would be interesting to be able to match up the camera movements with the motion of your head. this was one odd part in using the pure 3rd person view. In order to look around you had to move your whole body. this felt unnatural. Using a gyro and a camera pan-tilt servo mount would allow us to have the 3rd person view which would move with your body and head. This would most likely increase the immersion as it is closer to reality.

Live video switching
And as I mentioned before. We are in the process of adding a video switch for the multi-view case allowing us to switch between views on the fly.

Upgrade our workshop
While we can make do with what we have, we could definitely get some new tools. Some things we have in mind are the following:

Craftsman 10'' Bench Drill Press with Laser Trac
Drilling through PVC with a hand drill and a vice isn't the most ideal...

Craftsman PVC Cutter
Well, with all the PVC cutting this would have helped just a bit. 

If you have any other ideas, We'd love to hear them!
This instructable is amazing! After I figure out how to stabilize the camera I'm going to build this!! Great job!
What would make an ideal presentation of the whole experience IMO would be the<br>video of you walking around and a P in P of what you yourself are seeing at<br>the same time.<br><br>Meanwhile, congrats for a thoroughly entertaining instructable. <br><br>Love this website.
For outdoor use only it is HMMM<br><br>YODA!!!!
just a thought but would a higher view with a wide angle camera give a better perspective for the 3rd person view?
That is really cool i had an idea for something just like that, but the camera had a wireless feed because it was placed somewhere not atached to you<br>
The first line of this instructable is inaccurate:<br><br>&quot;This is a project which will literally pull your mind out from your head.&quot;<br><br>You don't mean literally. That sentence works if you delete &quot;literally.&quot; You mean the opposite of literally: figuratively. But we get that as long as you don't say literally.<br><br>In current popular usage, the word &quot;literally&quot; is not used literally or correctly 96 percent of the time.<br><br>My work here is done.
Hi. Positive and constructive comment here. While you are perfectly right about your previous statement, I would think that you would at least comment on his instructable. Spelling, punctuation, grammar, etc. are not the main focus of this website. It doesn't look good when you criticize someone about the correct way to use a word and totally ignore their hard work. If you haven't already, I think you should apologize to BigRedRocket for starting this catastrophe and distracting people from his work, even if you didn't mean to, and give him his due respect. <br><br>With that being said, great instructable BigRedRocket!
The instructable was okay, if you mean everything but the words which comprised its presentation. (Hard to separate an 'ible' from the words that comprise the text, since it's mostly text.) But I can't apologize sincerely to BigRedRocket, because I was sincerely interested in helping him. If he can't see that, he didn't read my comments very carefully. I would like to see his ability to process words become equal to his ability for innovation.<br><br>He might have been influenced in his (incorrect) choice of words by the epidemic of people currently misusing the word &quot;literally.&quot; If some of those other people had learned from someone that literally losing your head is always fatal, then maybe Red wouldn't have made that mistake. But maybe some of those people reacted immaturely and emotionally to a helpful suggestion, and the lesson didn't take.<br><br>I'm just saying people are responsible not only for their words but also for how they respond to lessons presented with good intentions in a friendly manner.<br><br>Boss, it seems you might be one of those people who feel that even helpful criticism must always be balanced equally with praise, or the recipient should reasonably be offended. But I don't think that expectation reflects much faith in the maturity of the person being helped, and it makes no sense to me. My education wasn't presented that way, nor did I need it to be. This might well be also a lesson in not infering or inventing insults that just aren't there.<br><br>Let alone a &quot;catastrophe.&quot; That reads to me like just more hyperbole. Words mean things, and it's good to use the right word for what one means--especially when trying to be clear in a teaching mode.<br><br>I wish you and Red well. If I didn't have a glad heart I wouldn't have bothered with my first comment.
How old are you? Because you are acting like a rude 10 year old who just learned how to use words in a sentence and went on a correcting spree.
You didn't have any work here... be gone
Who gives a literal how he used literally we got his meaning.
We got his meaning because we decided he didn't mean what he said.<br>
We got what his meaning was because we didn't take his meaning, of literally, literally... did you get what I mean by that or is my meaning to literal for you to understand my meaning of understanding the meaning of his literal meaning?
Do you know the difference between to, two, and too? You may not be ready for more complicated concepts like &quot;literally.&quot;
You're literally being a tool.<br><br>On a more constructive note, the &quot;position&quot; of the mind is highly linked with our visual reference point - thus if our vantage point is outside our body, as it is here, after some adjustment time we will feel like we are living outside our body. So your mind is literally pulled outside your head.<br><br>Your work here was awful, you are fired.
hughperman, again, you're using the term &quot;literally&quot; in a superfluous and non-literal way. Take your last meaningful sentence:<br><br>&quot;So your mind is literally pulled outside your head.&quot;<br><br>It works if you delete the word &quot;literally.&quot; Otherwise it creates an odd and meaningless image. A mind cannot be literally pulled anywhere. Only figuratively.<br><br>A lot of people have the idea that adding the word &quot;literally&quot; to an otherwise perfectly good sentence somehow increases the intensity of meaning. It doesn't.
Absolutely an awesome idea. There's many camera rigs out there, but this one is unique because I'm not quite sure if I've seen it used in videos before now. Anyways, I can see tons of potential in it. You could make videos of what a &quot;real life&quot; third person game would look like!
Thanks, you inspired me to make a similar rig for filming.&nbsp;It's on a very long boom with a 0.45x lens. Wobbles a lot, but seems to recover fast. I'll see how it fares with MTB trails :)<br> <br> <div class="media_embed"> <iframe frameborder="0" height="349" src="http://www.youtube.com/embed/63wSisnONk8" width="425"></iframe></div> <br> <div class="media_embed"> <iframe frameborder="0" height="349" src="http://www.youtube.com/embed/-yCgZ7EB80k" width="560"></iframe></div>
would it be possible to do this with only one eye instead of both? (kinda retarted, bear with me) I'd like to know what it'd be like looking both in front and in back of me at the same time.<br>firoblackfire@yahoo.com
Sure, although I would imagine that it would mess with your head. It would be a neat experiment. <br><br>The goggles I have can take a 3D video source input. That requires a interlaced video signal which is difficult to generate. If you can find goggles that take in two separate video sources it would be a lot easier.
That is awesome. If I had that on, I'd keep thinking I was in a video game. Which isn't really a bad thing :)
Reply from Qu&eacute;bec :P <br>Nice project. It remember me a project I made. I used a small circuit from a broken IR remote controled car (+- 30grams) with a TIP4*** for drive the camera righ/left with a 9-12v geerbox from a BBq chicken turning rod... U Know... It turn veeeeerrrrrryyyyyyy slow. And used the front/reverse for the zoom <br> <br>I don't what imagine the feeling with as wiimote attached to your head/neck!!! Remember ROBOCOP <br>
Ingenius idea :) 5/5 instructable<br><br>You might want to really tuck away them AV leads though, so a cop doesn't shoot you thinking you have a bomb.
Indeed a good observation
Thanks, yeah it does look a little nefarious. We were in the middle of nowhere behind our school, so there were no issues.
I might do this with a GoPro camera then it would be crystal clear video and a 170 degree view.
you don't need 3d cameras just a bit of math, another camera and some more pvc pipe. more work but a couple thousand dollars cheaper.
The goggles only have a 3d video input. I can't hook up two cameras and then 'use some math' and attach it to the goggles. It requires interlaced video. <br><br>Most of these off the shelf goggles have a single video input, and they typically have a single LCD inside with optics to split it up. Ideally I would have goggles with two independent screens with separate inputs, then it would be easy.
the 'math&quot; i spoke of was for the placement of the cameras. there are several stereoscopic image splicers (or whatever the hell there called, they had a spiffy name) on the market that will take the dual input of two separate cameras (weather it supports component or not, i have no idea) and output in various formats, interlaced being one of them (some support shutter glasses). while i haven't heard of anyone using these to view themselves in 3rd person i have seen them used for other portable projects (ie. on top of a rc car) so look around maybe that will work for you. or find glasses with separate inputs...
Have you seen any of these multiplexers for a reasonable price?
would be nice if they redesigned the camera mount and made a sensor so that when the user looked up, down, or side to side the camera would move to with his head movements.
Yeah, we had thought about this. It would be pretty easy to do, but we didn't have the time to get that working as well.
That is awesome :D
awesome! i'm going to try to build one of these from my birthday money
nvm looks like a 98 custom, u just mounted that scope on it, in the video it looks different.
what paintball marker is that? it looks like some aug... and if i were u i wouldn't actually try paintballing wit that
ur weird.<br><br>too much video games
press button on shoulder, so when you look down sight it switches camera's. run of arduni or something.
this also could be useful in creating some non-human halloween costume
Great Idea. I can just see it being implemented into a game environment and used for such. If you guys have any experience with game making you should look in to it.
great instructable. <br>recently saw one of these at an airport and it seems to fit nicely with what you want to do <br>http://ardrone.parrot.com<br><br>its software is open source (GNU)<br>head tracking was accomplished here<br>http://www.youtube.com/watch?v=JyX8WnO2ml8<br>with a little coding perhaps some extra cameras and some http://www.vuzix.com goggles <br>you could have the third person view of your dreams<br><br>maby you could try using galvanic vestibular stimulation to control the person.<br>http://www.youtube.com/watch?v=Kf0E9llkZIU
I wonder how what it would be like to reverse the camera and show the image only to one side of the goggle. Then you would really have an eye on the back of your head. One eye would see in front and the other would see behind. I wonder how long it would take for your eyes to adjust, if ever.
cool proyect! In this picture, what are those wings hiding in the roof? seems intresting
Dude Are You Trying to get some one killed?!! You look like a terrorist with that bag and wires hanging out some one might think they are doing good by killing you. Anyways I'll hear it on the new lol. J/k I don't think its that serious. The head band lol makes you look more like one..
So awesome! Very very trippy project! I'd suggest just one mod though; is there any way to make it so that the camera doesn't move so much in sync with the wearer's body? I mean if the wearer bends his torso to the right, the axis of the camera should be the same! Basically how would one go about making this as close to 3rd person view in a game GTA, for example! Would be an extremely insightful way to experience the world for a few hours.<br>In any case, i'm very taken with this project; you're allowed a change of perspective for a little while! Awesome! :)
Yeah. I would love to see that. We tried to isolate the camera as much as we could from normal movements, but large motions show up. It is challenging to get it to move with you most of the time, but not with you other times. <br><br>The one idea I have had is to take a small balloon and attach it to ourselves. Being clever about it, you could treat it like a kite and possibly keep it in line with you. That would isolate movements, yet keep it attached to you.<br><br>And as other have mentioned, using a servo system to move the camera along with your head motions would help as well. <br><br>This is in the works :)
Interesting Instructable for sure,&nbsp;at least i find it as such,&nbsp;as i built a tethered version a couple years back as a AV experiment&nbsp;using three people each allowed to view the others perspective... I got the idea from some movie i watched - ( the one in the movie was wireless as well and actually tapped into the brain of the first party wearer and recorded it so when viewed by another you got the smells etc etc with the experience. but there was a sceen where two shared this thing and it gave me an idea to try and build it. - It works great though much less advanced than the percieved one in the movie and not wireless like yours)<br> <br> This does have me thinking on it again though and may try to build it wirless - though not as powerfull - maybe using a 5 ghz connecttion and a HD web cam...<br> <br> thanks for the insight you your model. Looks like fun!
Sorry if someone has already had this idea. <br><br>A person who has no obstruction of their own vision has a camera mounted on their head, maybe even in those camera glasses. The image from this camera is sent to the second person, who has the video goggles on. So person 2 sees themselves from the view of person 1. Provided the other person always walked behind you, you would have a very, very interesting view of the world.
what is next? <br>a thermal visor, a gun mounted camera...? <br>the technology is the same and if you play paintball can be great
