reported IHADSS symbology not eye level in VR

[Vettecor]

I have to look up to see the symbology, particularly the cross. It causes considerable eye strain. I have tried with 2 different VR headsets, same outcome. The IHADSS needs to be lowered. It is also impossible to correctly perform a boresight alignment.

Hi, 

the team have checked on various devices and found it to be in the correct position. 

I will ask the team about considering a adjustment for user preference. 

thank you

I have now tagged this reported as we do have a task assigned to the team for review. 

thank you 

[BIGNEWY]

please add any screenshots you have as examples. 

Can you confirm the headset is seated correctly and calibrated with the environment?

thank you

Perhaps associated with this, I have found that to see the heading tape, at the top of the IHADDS, I need to either raise my eyes significantly or lower my head, until it feels like I'm going to soon be looking at my RL knees.   The latter solution above does still also require me to raise my eyes, relative to my head position.

Alongside this, particularly when I take the first solution above, I get pretty significant flickering of the heading tape.  This reminds me of the effects of the early implementations of ASW, in the Oculus Rift CV1, where it couldn't cope with the sorts of thin straight lines that appear on HUD-type displays.  I am currently using a Quest 3, via Virtual Desktop, using SSW, and although that might just indicate an issue with the *SW features, the rest of the IHADSS display is rock-steady when you look at it head-on, as it were.

I'll have a tinker around with the SSW settings in Virtual Desktop and see if I can correct this behaviour, but in the meantime, I can at least add my view that the IHADSS does appear to be a little on the high side.

 

Edit:  It would appear that it is looking through the IHADSS, with the spinning main rotor in the background, that is causing the flickering, so not sure whether this can be rectified?  

As for the high heading tape, looking down a little, when resetting the VR view, does appear to lower the IHADSS, as does "lowering one's seat" via RCtrl&RShft&numlock 2,  it may be that a tweak of the VR pilot's initial position might therefore be a more friendly solution, than having to fiddle with it after starting each flight?

Here are 2 screenshots. One is VR, Pimax Crystal. The other is no VR, 2D monitor. I confirmed calibration in the Pimax app settings.  I repeated the VR re-center several times to be sure. I have to tilt my head down quite a bit to match the VR center to the 2D center position. I also tested the HMCS on the F-16 as well, with screenshot. The boresight cross on the HUD is eye level, but the HMCS cross is slightly elevated. Perhaps it is just my VR headset. But there are no other settings parameters to make any adjustments. Any helmet display with the ability to adjust the height would be very beneficial, if that is even possible to implement. Thanks.

I believe that the issue is that the symbology for the HMDs in all aircraft is referenced to the vertical center of the display.

For some players, this will coincide with where their eyes look  when at rest in the center of their travel in the head.

For other players, this may be too low or too high.

it all depends on where the HMD sits.

In my case, VR headsets tend to sit too high, i have pretty high cheek bones and a relatively tall forehead, which move the headset up on my face.  This results in the centerline of the headset being 5-10 degrees above the natural resting position of my eyes.

 

In the AH-64, there are keybindings to shift the symbology up/down and left/right on the display.  HOWEVER, this has two problems

1. Not all symbology gets shifted.  Specifically, the AQC cuing dots do not shift with the rest of the symbology (i will upload screenshots showing this when i get off work, typing on break now)
2. the line of sight computation of the HMD is not adjusted, even after redoing IHADDS alignment (I will supply a track after work)

 

As a result, i end up just having to put up with eyestrain induced by the display not being where it needs to be for my particular face geometry.  sucks, but i can understand why it's not a super high priority for ED to fix.

@BIGNEWY I recall that you like to get an @ when we provide tracks and whatnot for troubleshooting.

As promised, track file: https://drive.google.com/file/d/1cgTwJ07uRa1M5ovqui3qkGcCT9XE_Chv/view?usp=drive_link

Sorry for the Google Drive link, but the track exceeds the 12MB limit for a forum attachment.

In this track, after spawning in, i function check the IHADDS, particularly the ACQ cueing dots, everything is good, but the IHADDS crosshair is significantly above my physical line of sight.  I then bring the crosshair down to my line of sight using the DAP controls.  We can see that after i do this, the ACQ dots are at the same angular position relative to my view as they were before, placing them well above where the crosshair ended up.

I then center the IHADDS and head off to the range to test it.  Opening fire on a tree in the distance, we can see that my shots go FAR beyond the crosshair, but are pretty close to the center between the ACQ dots.  We can even see in a few cases that the ELE LIMIT warning is displayed while the crosshairs are still pointing down towards the ground.

I then center the symbology back in the middle of the ACQ dots, re-boresight the IHADDS, and my shots start going exactly where i place the crosshair.

 

I also recorded video of this, which i am uploading to YT now and will add to this post when complete, for those who do not want to futz around with the trk file.
