JHMCS using track IR

After finally finally finding some footage of the JHMCS in use, I have a request.

In the real aircraft, the JHMCS symbology is only displayed when the pilot is looking a certain number of degrees left/right and presumably up from straight ahead. This makes sense as otherwise it would be conflicting with the HUD.

My current setup is a 95" projected image for the outside world and a helios monitor for panels, but I am working on a full pit. Due to the huge screen I don't use/need TrackIR to pan the view, but what I would really love is the ability to have TrackIR sense my head position and enable/disable the JHMCS display based on where I am looking.

TL;DR: have an option that independently enables:

* TrackIR controlling the external view shift

* TrackIR enabling/disabling the JHMCS display based on where you are looking

My super wish list item is that the JHMCS is exportable as a view for once I figure out how to get a tiny projector mounted in a helmet ;)

Pretty soon, the hobbyist pit systems will be approaching the real thing :D

Let us know what you figure out.

I'm somewhat confused as to what you are asking for? It sounds like you wont be using TrackIR to pan the view so the centre of your view will stay looking forwards (towards the HUD). And you want TrackIR to activate the JHMCS projection and presumably move it around the screen so it stays in the centre of your vision?

This is a complex problem. How will the sim know where your IRL head is looking? You'd have to have some kind calibration system that would make you look at certain points on the screen so the sim could work out the relationship between real head movement and the screen... and thats just thinking about 3DOF.. Add in 3 other axis for 6DOF and it becomes even more complicated! :dontgetit:

OK so now that I think about it's not as simple as I first thought. And that is because the size of the display and the distance from the IR tracker to the display are both variables. So a certain degree of head yaw is going to make a bigger impact on look offset on a 22" monitor than it is on a 95" projector.

However, ED are smart cookies, and I strongly believe that they could implement a fairly simple calibration system that works by getting the user to look at 5 points on their display: centre, top, left, right and bottom of screen.

took me a few times to figure out this is to ensure jhmcs functionality from 3pv?

elaborate on the need to hide jhmcs when looking forward in 3pv when there is no hud element?

No this isn't for the 3rd person view, this is for the cockpit view with the cockpit hidden (shift-F1).

Hi,

Is it possible to use the track IR to move the JHMCS instead of the camera? Or at least moving the

JHMCS exponentially with the track IR curve.

For people how have a large view (3 screens) I think he's a good idea.

Thanks a lot!

[Edit] Screen :

It should work by default once you've switched on the JHMS using the JHMS power knob, it appears in your field of view wherever you are looking.

No special commands to use it other than the power/on/off knob.

Yes but it's not that I Want.

1/ Only move JHMS with the Track IR (not the camera/head + JHMS)

2/ If camera + JHMS, move the JHMS following the curve or the track IR and not staying in the center of the screen : if I move my head to the left, the JHMS should also move to the left more and more to the left too, to "follow" the eyes and not just stay in the center of the monitor

[Edit] I see i'm not alone : https://forums.eagle.ru/showthread.php?t=199495

I must be misunderstanding you? The JHMS is projected onto the helmet visor, it CANNOT move independently of your head/camera view. (that's what the '..HMS' stands for HEAD MOUNTED SIGHT).

I copy a sentence from the link above :

Due to the huge screen I don't use/need TrackIR to pan the view, but what I would really love is the ability to have TrackIR sense my head position and enable/disable the JHMCS display based on where I am looking

there's no way to use a head mounted sight without moving your head, TrackIR or no TrackIR. I understand you're using triple monitors and so don't want "head tracking" persay, but what you're wanting is kind of counter intuitive from the game's perspective. The in-game pilot has to turn his head to use the HMS, which is also your camera.

I also question the value of this even if it were available, as if you weren't turning the camera around, the only directions you could lock would be ahead, and somewhat to the sides. In a dogfight (where you would actually use a HMS), you will normally be needing to look UP as you'll be rolled toward the target and chasing it. In other words, if you're not moving the camera around, the HMS has lost a substantial portion of its value in the first place.

What?

It's not at all what I'm saying.

I say : I want a track IR to track the movement of the JHMCS with my head instead of the mouvement of the camera. Like the IRL!

IRL you don't move the world with your head, but only the JHMCS (helmet).

the track IR IS the helmet, and move the JHMCS on the triple screen like IRL.

the track IR DON'T MOVE the camera/pov/whatever but only the JHMCS

Thanks for making that image, the picture clears up a lot and I’m pretty sure I understand what functionality you’re looking for. As far as I know, the JHMCS is tied to wherever the camera is pointing and I don’t know of any way to change this. Keep in mind I have no experience at all with triple monitor setups, especially not in DCS. As I understand it, the three monitors provide you with a fixed camera view, and you want to move the JHMCS around within that area. Again, I don’t think this is possible, but like Zhukov stated, I don’t understand how useful this would be since your viewpoint is fixed (unless you using a hat switch or something to move your entire field of view up/down or side to side.)

Yeah, I can use a hat switch and/or a on/off camera head tracking using the track IR, where's a lot of possibility and this is the "Wish List" section, not a "why???" section :p

[Edit] And the "best" I think is to have 2 curve. One for the camera view and on for the JHMCS

Up!

I have play with a 270° screen dome and I think this option is really necessary for this kind of case.

IMO, sphere projection is probably one of the best approach that can take advantage of a fully functional sim pit to achieve the ultimate simulation experience. In this case, I believe using Track IR to control JHMCS without moving the view port / camera is a legit request.

If I had the cash to spend, I probably would do something similar, though I currently use VR which is a cost-effective alternative with some trade-offs apparently, for example: interacting with cockpit controls.

as someone who uses an ultrawide display with TrackIR, i feel your pain. 

For those who dont understand the problem

Normal TrackIR usage: Turn head far enough so you can see what you need to at the right side of the display. 

JHMCS is always centered

TrackIR usage with JHMCS: turn head far enough to that what you want to lock centers in the display (for JHMCS)

One of the benifits of multiple monitors or an ultrawide is that you can use a lower angular multiplier. 

Low TrackIR multiplier with JHMCS: turn head so far to the side in order to center target that your eyes cant see the center of the monitor. (ie you cant see the target or JHMCS FOV)

If JHMCS could dynamically offset with head input, it could be made to follow your central vision. (ie if im using TrackIR, and I look right, offset JHMCS to right side of display)

With my triple monitor setup, HMD equipped aircraft are awkward to use the HMD as it only utilizes the center monitor. I have seen a few sim builders not using HMD in jets for this reason if they use multi projector setups etc. TheWarthogProject is famous for not using HMD on his simulator when using it without VR. Iceman's post Here identifies the issue well.

I would like to see a way we could tune the movement of the HMD or at least have it slew over to another monitor.

The setup for reference that I use see the linked post for Iceman555's setup details. I noticed the issue after adding a head tracker also was seen when I used a joystick on the throttle to look around. 

A few more threads talking about this. 

Hello,

I´m facing the same issue...  Have anybody found a solution for this?

Thank you!

@BIGNEWY Is there a way to move HMD with TrackIR while the cockpit view is fixed?

We really need this for us cockpit builders @BIGNEWY
Ist here an official statement from ED to this topic?

Is there a way that can export 2 views that one fixed(for the big real display) and another use trackir as normal(not realy use,only in monitor,or only render the HMD),meantime export the hmd? @BIGNEWY
