TrackrIR

[Vinkman]

Randy, check here for a write up on TrackIR http://bbs.hitechcreations.com/smf/index.php/topic,329017.0.html

Also a tip from me. don't shut off the X,Y,Z as Bino said, those axis are invaluable, BUT note that the vertical axis can cause significant problems as a side effect of moving your head fore and aft. This is due to the geometry of the camera being higher than your TrackIR LEDs. So as you move closer to the screen, the camera has to look "down" to see the LEDs. This is interpreted as your head moving down, and makes it very difficult in planes like the F4U, where you need to move your head forward and up to look behind you.

The cure is a simple one. Reviewing Fugitive's write up, you will see the plot showing the "scaling" of the track IR sensitivity. Notice that the plot is V-shaped, meaning mostly "Symetric".  If this was the Vertical axis, it would mean your view moves Up and Down from the off center position with similar amplitude to similar inputs. But the plot does not have to be v-shaped. Uncheck the "Mirror" box and then up and down can be set seperately. Turn the sensitivity for the part of the motion LOWER than the center position to a very flat slope (I believe that is the left side of the plot.). Then turn the sensitivity for the motion ABOVE center position parabolically (as shown in Fugative's example). Now your head can bob up and down to see over the nose, and behind you, but will never go below the "centered" position when you move forward or backward, or any other direction.

Hope that helps.

Vinkman, I had turned back on the XYZ but the plots are the presets.  I will set it as you suggested and give that a go.  That sure sounds like a good idea and another place for a fine tune

I can look back without any problem on the La7  since there is no headrest.  I can look back on the P51 or the P47M around the head rest by leaning to right then looking back left but that does not always work.  Is that the way everyone looks back or should I push the xyz plots to get it to read a look right and back?

If I get a chance today I will set up a new file and push the setting to take advantage of the power of the TrackIR.  Until now I really had not grasp all the ways the system can be modified.

I have use the speed slider to slow it down and smooth slider to smooth it out.  I try to be able scan read the degrees as they slide by in the setup window.

Randy, you should be able to look lean right, turn right, to look behind you to the right. There is a box to select in the AH View menu of the Clipboard that says TrackIR move relative. That needs to be sected along with a matching check box (it has a similar name) in the track IR software. The reason this is important is that you always wnat the direction your virtual head is facing to be "forward". For example if you are sitting in the plan looking forward and you move your head towards to the monitor, your virtual head (or view) moves towards the instrument panel of the plane. But when you turn your head enough that you view is looking over the seat at the tail of the aircraft, you want to move your head away from the monitor to get your view to pull back from the seat so you get a bigger view of the tail section. So the software has to reverse all the inputs when your "virtual head" is looking behind you. Checking these boxes will do that, and the Track  will work intuitively just like moving in real life would. Many don't understand this about TrackIR and end up learning to use their head like a joystick, instead of like...well...your natural head movements.

Hope that helps.
