I need some help with this. Been annoying me since can't seem to get to work and every thing I look up shows my camera works and tutorials from youtube are use less in this sense even though using same camera as me. Sorry this seems a little mean I am upset due to spending over 6 hours trying to play with the settings.

I am in the exact same boat. One round I was using it was perfect. The next round the camera kept losing my face. Was driving me crazy.


I am going to build an IR LED set up. A friend is going to send me his plans for his LED build, and I'll forward them along.

Alright. I got the camera now working. Now a new task on hand is to get the camera past 15 fps. The hard coding of the input of the camera was none which I had to change. I love when drivers don't install right.

And I been noticing designs like that would like to put one together.

Thanks for reply.

i was looking around about that and i found this guide:

This build also looks promising(not tested yet):

I built it, tweaked it, and finally got it up and working. Still need to get used to it, though. Apparently when I'm on the tail of a bandit, I shake my head around in excitement. This is normally fine, until your head is in the tracker and you're trying to look down the god damned gunsight.




It's a simple circuit. 3X 1.28 volt, 100 mA IR LED's wired in parellel to a 100 ohm resistor attached to an AA battery holder. I squared off the tips.


Now here's the tough part. You gotta play with the Point Tracker API settings so that the IR light "gain" is down, and that it only picks up the IR LED's. Then you gotta play with your "Curves" like crazy to get to what you want. Your "Curves" define your Input to Output setup. I.E. If I move my head an inch to the right, it equals a foot in game. If I turn my head 10 degrees to the right, it equals 90 degrees in game.


One thing I have noticed is that my build is too big. I may build the structure again and make it 75% of the size.

[spanakis]

sweet , what are you using as a receiver ?

To reduce the size i would suggest some smaller cables try using the cables from a LAN cable (CAT 5 or something) and you can power up the LEDs from your usb port , use black and red for +- and tape tape the rest (data cables).
The usb port will give you 5v, IR LEDs use 1.5v and 50mA so with a 80-100 ohm you will be fine

I use a Sony psEye Webcam with the IR Filter removed. I may yet put another IR filter like developed film over it because it sometimes picks up extra inputs.


I considered using cables as the frame of the support, but it wasn't rigid enough in my opinion. If you bent one while you were using it, you'd be screwed. So I used a hacksaw and cut out some sections from an H frame political sign steel support.


The IR setup cost $20, including the wire I had to buy since I lost mine somewhere. The PsEYE cost about $15 IIRC.

You can try getting a cheap hat and mount the LEDs in the front it will be stable enough (i think).

[AOD_Danneskjold]

Two things.


1.) That would mean that I'd have to wear a hat while playing...


2.) The brim of the hat can partially obscure my view.


My current set up works well, just have to tweak it.

and you are ready for simulator battles lol

I've been playing with this a couple days, and I'm enjoying the hell out of it! It is so damned useful to use your head and just look all around you at will.

[Tetsuo]

This looks interesting. Will have to try to build one most likely. Thank you for the links Spanakis.

I was using FreeTrack / Facetrack software (even with the IR LED set up), but it was cutting out on me, for whatever reason. Couldn't figure out what the problem was, so I switched to "OpenTrack" and it's working beautifully.


It is so awesome and useful. For example, the other day I was testing an FM, and decided to leave the tracker off. And even though I've only been using it a couple days, I found myself twisting my head trying to look around.

[Tetsuo]

Try playing with curves if don't want to twist your head so much. I played with it for my face cam and got it to a point I like not to much twist in my head for a full look but makes moving the head more tricky.

[spanakis]

i finished my headtracker ~10euro total cost using accelerometer and an arduino pro micro , it works perfect i will make a separate post tomorrow with details and photos.

If you don't like the idea of a hat use a visor. I didn't like wearing a hat because it felt weird with my headset and the visor works great, stiff bill and I don't pull it down far so i does not block any of the screen.

Head trackers are awesome to fly with, until you try it with mouse aim in third person. I found that hard to deal with.

Nice work on the build
