Head Tracking with Cliffs of Dover

[Royraiden]

EDIT****If you want info about the questions I asked dont read this thread because it is full of useless off-topic posts mostly by two sad fellas.

Having already ordered a HOTAS+Rudder pedals for this sim(thanks to all the kind members for sharing your thoughts and experience on my other thread),now its time for me to consider upgrading my head tracking setup.I've been using Freetrack for the past year with almost no complaints regarding the software.On the other hand, due to my poor craftsmanship, my 3 point clip started failing on me,something I was expecting because that thing was held on by layers and layers of duct tape(yes it was a pretty cheap build).So I've read several times that I could use the Natural Point Track Clip Pro with Freetrack, and went to their website to order one.I can get it shipped for $60.00.If I would have know these from the start I would have saved the money I spent on the webcam+ tools and parts and go all out for a TrackIR solution.My main concern is,how can I be sure that Freetrack is going to be supported when the game comes out?If I could choose I would stay with freetrack because its a great piece of software,and the fact that it is free.Though there are a few advantages to owning Track Ir.The most important for me is the reflective Clip.Having the 3 point clip with Freetrack means that I need to have my headphones on in addition to another cable hanging around my face.I guess I could build a reflective clip for Freetrack but I honestly dont want to fiddle more with parts.



Freetrack
Pros:
-FREE software
-Easy to set up and use once you got the setup built correctly
-Easy to replace(if the camera fails)

Cons:
-Support(not all games supporting track ir support freetrack, correct me)
-Bothersome to make clip(at least to me)
-Requires a dark room to work properly most of the time

TrackIR
Pros:
-No need to build
-More complex software(im assuming)
-Comes with reflective clip(does not need a dark room to work properly)
-Better support on games

Cons:
-Expensive!

I guess there are more cons but since I dont own a TIR setup I dont know which ones.

If I decided to go for the TrackIR I would try to get the TIR4 but it isnt available on amazon and theres just a few on ebay.Where is the cheapest place I could get one?Feel free to correct my mistakes, if there's any.Give me some advice/suggestions/experience.And most importantly,is Freetrack going to be supported at release?Im fairly new to the forum so maybe this was discussed earlier.

Would be good to know the position of OM. Have they blocked access to needed information as Eagle Dynamics did with DCS:Black Shark(because Natural Point payed it)?

Well, Ilya has been shown using TrackIR in 2 videos.In one of them he was actually talking about it.

Instead of making a setup that tracks three infrared lights, just mount a few to shine towards you (high output LED's if possible) and just make your own reflective clip instead. That way you don't have to have a bunch of wires hanging from your head, and the LED setup could run off of a power source other than batteries. (think replacing one of those USB LED lamps with an IR one).

-Support(not all games supporting track ir support freetrack, correct me)

Could be, never found one that doesn't support Freetrack though (Black Shark needs a fix though).

-Bothersome to make clip(at least to me)

You can buy the TrackClipPro (yes, pretty expensive, but still less expensive then TrackIR). This might be a problem if you don't wear a headphone/headset.

-Requires a dark room to work properly most of the time

Not if you use IR LED's (or bought the TrackClipPro).

I'm using Freetrack with a VX3000 webcam and the TrackclipPro and it works perfectly, no reason for me to get TrackIR.


If CloD won't support Freetrack, i'll be very disappointed.

Thanks for your replies.Indeed a lot of people will be dissapointed if there's no Freetrack support.That is why I havent bought anything yet.

does FT still hack from TIR software?

No Im not using IR led's though I thought they were when I bought them.How's the build quality?I read somewhere that it broke fairly easy.

It seems very fragile indeed. I have it for 15 months or so and it's still in good shape, it won't fall apart by looking at it, but it's definately not sturdy, especially not for the price, if it would cost 10 € or so, it would be a fair price imo.

I had some problems with power outages and surges recently that resulted in my power supply getting fried. Thankfully, the rest of my PC survived and the PSU was replaced for free thanks to a 3-year warranty, but the whole thing ended with my TrackIR 4 camera going dead.

I was of course considerably annoyed (to put it mildly ) because i didn't want to buy a new set, but on the other hand head tracking is one of those things that once you get used to you can't go back.

So i installed freetrack and after some tweaking i can use it with a cheap microsoft lifecam vx-5000 and my battered trackclip Pro (that thing is so notoriously flimsy that i've had to use duct-tape a mere 2 months after i bought my TrackIR+trackclip Pro set).

I use my webcam to place skype videocalls to relatives abroad, so i change the camera's configuration back and forth whenever i want to use freetrack.

Also for the same reason i haven't modified it (didn't remove the IR filter), but the IR leds from the trackcklip still register if the room is dark.

Granted, my initial observations are a bit tinted by the fact that i haven't tweaked freetrack to my taste just yet, but truth be told if i could spare the money right now i'd buy a new TrackIR set.

Don't get me wrong, Freetrack is a very good solution and i hope it's supported in CoD. However, coming from 2-3 years of TrackIR use it seems to me that TrackIR is definitely better (or just something i'm used to).

My comparison will focus mainly on the things that i think trackIR does better, not because i want to diss freetrack but because if it was equally good i'd be just saying "omg, it's as good as trackIR and free, definitely prefer it!" and be done with it

For me, the points i personally disliked were:
1) There's a noticeable delay between moving my head and freetrack doing its job. I guess this is not an issue for someone who's new to head tracking or only used freetrack in the past, but for someone who's used TrackIR and got spoiled by its near instantaneous response the delay is noticeable.

2) The freetrack software is definitely more complicated than TrackIR version 5 software, but it's more or less on par with the older trackIR version 4 versions. I guess that's the price one pays for the ability to customize, more parameters and so on.

3) The keys i use to control freetrack sometimes have trouble registering. I use F9 to pause it and F12 to recenter. Sometimes i have to keep pressing 2-4 times before it does what it's supposed to do. The biggest drawback in this is that if you pause it, it seems to also deactivate the camera so when you resume it you have to wait for the webcam to also do its own "start-up". It's not a century of delay of course, but it's a noticeable and often crucial few seconds.
With trackIR, i could point my head into a weird angle, pause the device at that spot and turn my head straight on the screen to keep looking that way without straining my neck, then i would press F9 again and it would instantly start following my movement again.
With freetrack, i find that it will probably take 2-3 attempts to do it and then i'll also have to wait a few seconds for the webcam to come back to life.

4) Trying to set a proper curve for one axis in Freetrack is driving me nuts. The trackIR method (especially in the version 5 software) is definitely superior by leaps and bounds.

5) Accuracy is not the same, even when using 640x480 webcam video resolution. I also have a steady 30FPS with 0 jitter and the freetrack software clearly shows 3 dots being tracked. I won't hold this last one against it however, because i think it could be improved with some tweaking on my part.
I get a lot of "blind" angles, so for example if i want to look to my 5 o'clock the movement is smooth until a certain point, i get a blind spot where it loses contact and then it picks it up again. I think this could be solved by making my own custom IR leds and sanding them down a bit so they are easier to pick up, plus taping some photo film in front of my webcam to act as a visible light filter.

6) I get motion in an extra axis during certain movements. If i'm looking straight up the in-game view also rotates to clockwise some, if i'm looking down into the cockpit it rotates counter-clockwise. TrackIR had a bit of this too in the version4 software but definitely not so pronounced and it was totally eradicated for me with the version 5 drivers.
I think this is also a point that can be solved with some tweaking, as i think it has to do with setting the distances of the reference point in the freetrack interface.


Finally, my thoughts on a few improvements that could make freetrack even better.

1) Don't turn off the webcam when pause key is pressed, leave it running, keep tracking it but just stop the data stream towards the game. This would solve the wasted seconds between pause and resume.

2) A revamped interface for setting up the sensitivity curves. Keep the old one for those that might prefer it, plus copy the trackIR method as an alternative way to do it.

3) Have a way to automatically calibrate the reference point so we don't have to take a measuring tape to our heads
A 3-step calibration could be used, where the player needs to look straight ahead, all the way up and all the way down. The software could then extrapolate the reference point datum by measuring the rotational offset that's caused when looking up/down, because it knows it shouldn't be there.

My final assesment is that freetrack is not as good as trackIR in an absolute comparison, but it's better on a cost-effectiveness basis. If you want to get head tracking on the cheap definitely try it out, just be prepared to spend time configuring it and having to deal with a few frustrating aspects.
