4.1.029

[Mace2004]

OK, something seems real strange here. I've been using TIR4 since August with software 4.1.028 and usually play Aces High. I'd seen posts both here and the Aces High forum about people complaining in the way translation is implemented.

Specifically, people were complaining that when they looked to the rear they felt they needed to move their head in the wrong direction to see around the headrest. Again, this was with 4.1.028. Since I first started using TIR translation has always worked for me exactly as it should. In other words, if I'm looking behind over my left shoulder and my view was blocked by the headrest all I had to do was slide slightly to the right, exactly what I should have to do based on what I'm seeing on the screen. If I was too close to the headrest I moved my head back and my virtual head moved away from the headrest (obviously this was obviously moring my virtual head toward the front of the plane. Everything worked great.

However, there have been some complaints about translation dating back at least to 2005 before .029 alpha came out so they must have been using .028. Some complained that when you looked at 90 degrees and leaned forward to move your virtual head closer to the canopy the virtual head actually slid sideways (toward the nose or tail) instead of closer to the side canopy. My system with 4.1.028 always gave me forward movement when I moved my head forward, again, as it should.

I didn't have any of the problems people were complaining about with 4.1.028. Also, I have always had AH's TrackIR Object Relative Move set to off. I base my head movements on what I see on the screen which is the logical and natural way to do this. If I'm looking over my left shoulder and I want to look around the headrest I simply slide to the right and my view slides to the right on the screen even though technically my virtual head actually moves to the left side of the cockpit. When looking to the side, I move my head forward and my virtual head moves forward in the direction it's looking.

BUT then I tried out 4.1.029 Alpha and guess what. All the problems people were complaining about with 4.1.028 are there in .029. Look behind and you have to move your head in the wrong direction (to the left for the virtual head to move right relative to the screen). Look out the side and your virtual head moves toward the nose or tail when you move toward the screen. If you're looking forward and lean forward the virtual head moves forward BUT if you're looking aft and then lean back away from the screen to move away from the headrest the virtual head moves toward the tail, in other words its exactly the opposite of what it should do based on what you're seeing. Basically, it appears that for translation purposes the TIR is always assuming you're looking forward while the viewing angle is accurately represented.

What's going on? Why am I all of a sudden seeing the incorrect translations with 4.1.029 that others were complaining about with .028? (See the previous post started in 2005 about "leaning while looking behind") Am I missing some hidden control that would switch this back to the correct translations? If not, you've got a very serious problem here, TIR is unworkable with AH this way and I'd assume it's the same with other programs. Is this a software bug or is this the way it's designed to operate?I've switched back to 4.1.028 and everything works correctly again but 4.1.029 needs to be looked at very hard.

One thing to look at is in the individual profiles on the system. Under the Motion tab is a setting for TrueView, which enables and disables the natural head movements of the user within our software.

See if this is enabled, and switch to the "other" position to alleviate the difficulties you are having.

Roger that and thanks for the response. I'll check but will first have to reload the .029 software. I'll get back with you on the results. BTW, what exactly is "trueview" supposed to accomplish?

[VincentG]

- one of our other users described TrueView the following way

Picture it this way. I'll use a flight simulator as an example, because that's what I use, and it makes it easier to assign an arbitrary forwards and backwards direction for the explanation. In normal, non true view mode if you turn your head the translation axis doesn't rotate with it.. meaning if you look 90 degrees to the right (that is so in game your view rotates 90 degrees), then in game it would make sense that sliding your head to the left (relative to your head) would move it towards the front of the cockpit, in game. Instead it moves you to the left side of the plane. The translation axis hasn't rotated to follow the orientation of your head.

Where as in trueview, somehow they make it all work. I can look almost behind me, out a side window, and then if I move my head to the side (proper in game direction) I peek out over the edge of the window.

OK Vincent, I just tried it out and trueview is defaulted to "on", by turning trueview off it restores the correct translations. I've read your description and something is very strange as I'm seeing exactly the opposite of what you're describing. With trueview "off" the translation axis does rotate so when looking 90deg as you describe, moving my head to the left results in my virtual head moving toward the front of the airplane vice to the left side. Exactly the opposite happens with trueview on. With it on my translation axis doesn't rotate so the virtual head slides back (or too the left side of the plane).

As I said, this is very strange since I've heard others complain about the non-rotating translation axis (if I can call it that) with the .028 while I never had a problem.

Is there anything else that trueview does that I'm missing if I leave it off?

[VincentG]

Nope true view, in and of itself, does nothing extra than what I've described before.

OK, thanks Vincent. I was afraid there was a major problem. Appreciate the help.

No issues.
