Did you guys check this out or already talked about this HRTF device?
I think you're thinking about it wrong. I don't think anyone expects you to be whipping your head around in circles. It's more about small adjustments with your head while you're still looking forward.
Yes, your eyes should always be on the screen, but your head won't always be in the same position. People normally make small adjustments with their head to help pinpoint sound. It's the same thing a dog does when it tilts it's head to the side when it hears something. Humans do that too. An example is when you're looking for a hard to find sound (like a cricket in the house) and you sort of bob your head around to help you find it.
Unless your head is locked in place, you will most likely be making some small movements with your head anyways as you game. If you have a big enough screen, you might even move your head slightly when you look from one side to the other. You might as well make those movements contribute and sharpen the positioning and increase the immersion.
As Tyll says in the article:
I understand why you think it is useless (your in-game avatar will always be looking straight forward no matter what your head is doing), but still I think you need to try it first before you rule it out as being useless.
Recon3D USB should be here tonight when I get home!
AKG K712 Pro ought to arrive Friday (though knowing USPS, probably not till Monday).
Really though, right now... I just want a nap.
There's a really good post here about configuring your Recon3D USB set. I'd really recommend checking it out and following his advice. It's spot on.
As do I, which is why I don't give a whole lot of attention to virtual speaker surround devices that use head-tracking as part of their simulation. Any TrackIR enhanced mode game already does that for me, with the extra perk of a massive boost in situational awareness.
And for those that aren't, a bit of in-game camera movement works in its place for more finely discerning the location of sounds.
Now, if someone could make those ultrasonic head-trackers actually emulate a TrackIR, then I'd be really interested...
Eh, you make it easy to get to it. I have a couple friends who have picked up a Recon3D USB as well, fellow Mac gamers, and I link them your suggested settings to get a starting point. I get to it easily through your signature; "detailed report" at the bottom and then a link in that write-up takes you to the post. I don't have it bookmarked either but I think it's a great starting point for people. So I send them that way. But secretly, I'm actually too lazy to write down my settings for them and make them do their own work.
And forums aren't the best way to convey sarcasm/jokes/break dancing skills. It's pretty easy to get an impression of someone and have it be entirely incorrect. I mean, look at Chicolom. He might actually be a terrible person who punches puppies, though I highly doubt it. So if I may have come off a bit rude or provocative but it certainly wasn't intentional. Unless I was talking to Tus-chan. *shakes fist* (gotta rag on my fellow state-men)
Now that's just showing you haven't tried it... ever. Using headtracking, your eyes will never leave the screen. That would indeed be plain stupid. Small movements of your head are translated into bigger movements in game. It's almost the same as checking out the edges of your screen. Normally you'd do that with eyemovements, but you get used to using your head a bit as well.
For general gaming, RTS, MMORPG, or the run 'n gun shooters? Mwah, don't bother. But as soon as you enter the realm of simulation it offers huge benefits. Racing, flying or an FPS like ARMA are areas where headtracking stands out (or: all games where you need some sort of extra situational awareness). So I guess it depends on the type of games you play. Too bad you don't live around here, I'd let you try it out. If you even slightly like the type of games I've mentioned, you would go the headtracking route. Maybe not TrackIR as those are crazy expensive, but still... :).
