Gravity HUD Position and Clarity Questions

The HUD has its flaws, for sure, but I found out I’d rather have it than not after driving a loaner without it.
 
As a 5'6" driver I find the HUD to be clear, focused, level and useful. However, at slow speeds around town, turning corners etc, I find the HUD to be distracting while I'm trying to see around the extra wide A pillar blocking whole cars and pedestrians. The only way to guarantee seeing around the A pillar is to slide your head right and forward, then left and back to see around it.(like a lizard) This causes the HUD to disappear and then suddenly reappear just as you're accelerating forward. Numerous times this has caused me to slam on the brakes thinking a fresh victim has appeared.

As mentioned before, the HUD is great while navigating and I wish there was a setting to allow activating only while navigating. Ideally while navigating it would stay on as you come to a stop and stay on while stopped, until the car first moves and then, not come on until your fast enough that head waving is no longer required, maybe 4-5 mph.

I have my vehicle at the service center and asked them to check the HUD display alignment/tilt, while the performed some other service. This is their response and they told me verbally they need to get a test tool and have engineering present while performing the recalibration:

I had to have the vehicle flat bedded back, because I couldn't get a ride to Scottsdale (wife out of the country). So I got the vehicle back today.

The first thing I noticed was that the HUD image was was larger than the one I had before. It was also brighter, although I couldn't lower the brightness any (in bright sunlight). It appeared that if I lowered my head the image looked better. Couldn't lower the screen any more, so I lowered my seat. This was for a short drive from the entrance of my neighbor to home. Later when I went for a more lengthy drive, I raised my seat back up and the image continued to look good. The image was well centered and aligned to the horizon correctly. The only thing I noticed initially, which I either got used to or it corrected itself was that the image looked larger on the right than the left. I took a picture of the projected HUD image, but it didn't come out good with my iPhone. I'll try later with a real DSLR with electronic and manual shutter.
 
Huh; thanks for the report. I'm surprised they replaced the HUD, given the limited functionality today. Nice of them to try...

My HUD is clearly Not Right -- the yellow triangle indicator of right-side traffic is only half visible regardless of adjustments or movement. The info display, however, is all visible, so I'm not going to bother asking for service on this until there's a software update that actually enables AR functionality (which will surely not work).

I'm honestly surprised that they're continuing to sell and deliver units with the HUD. I have to imagine that when the AR functionality lands, it's going to require a recall and service on every single vehicle sold. I guess that's a future CEO's problem, and they get to recognize the revenue now?

From what I remember, they “hired” a company that specializes In HUDs and the software for them— can’t remember the name, but it’s in some thread somewhere here. I would hope they would just be able to update the software. I’m sure in some of their testing, Lucid was able to at least display static images and see how they looked, so I don’t think they would have to replace the display. And hopefully their display engine, which renders the pixels, is fast enough to do that correctly.

It is Basemark. However I think the general expectation is the HW design is probably going to be very limited viewing angle/seating position unfortunately. Hope we are wrong.

I have tried moving my head around, my body around, and what I did notice is that the position of the display relative to the road never changes. This is a good sign so that when they overlay Graphics , they stay in the correct position and are not dependent on the driver position.

This was a software partnership. I don't think that it involves the HUD's optical design.
 
I hope that HUD replacements are coming because it’s completely useless to me. I’m tall at 6’6” and even with the seat lowered to its lowest setting I can’t see the HUD at all while sitting naturally.

I actually thought our HUD was broken because I had it turned on and didn’t see anything. It wasn’t until I crouched way down that I could see that it was in fact on but just completely invisible from my natural sightline.

Hopefully, a new unit and adjustment can rectify this. My Gravity is in service for a while, so I’ll ask them what can be done.

I do not think the problem is a hardware problem, so I agree with you. But I do not know that for sure.

Maybe you can find somebody that lives in your area that has a HUD replacement. I’m in the Tucson Phoenix area if that would be helpful to you. Like I mentioned in my previous post, I had to lower my seat the first time to be able to see the display clearly – although it was visible. And later I was able to raise my seat back up and it was still clear. Maybe it has a self-leveling function now.
 
I wish the HUD offered a demonstration mode so you could preview its appearance without needing to drive. The screen adjustment feature is moderately helpful by outlining the display area, yet it fails to clarify how visuals will appear.

Yeah, here's the PR:
https://www.basemark.com/news/basem...ted-reality-head-up-display-to-lucid-gravity/

The challenge here is that Basemark provides the software for development and data presentation -- what should be displayed, where, and when. It still depends on the hardware to work correctly. Right now, I don't have any evidence that the HUD hardware can do the eye tracking and registration necessary for the software to display properly. I hope I'm wrong, but the fact that it can't properly render the existing data is worrisome.

Any indication as to whether the replacement HUD is a different iteration of the hardware, or just a functioning version of the initial hardware module?

That sounds great and gives me slight glimmer of hope. The two we have look terrible unless nearly in lowest chair setting and head tilted slightly downwards.

I probably won't trouble our SC until there is some big software update for it though.

My new (and old HUD) would always display the data in the same spot relative to the road regardless of how I moved around. I think that's just optics, no hardware/software eye tracking involved. When they actually have overlay data for the road, you will need to adjust the up/down to have it track properly. There will not be a need to adjust left/right, since this is taken care of by the built in optics. In the future, when the road curvature is overlayed on the HUD, there may be a poor up/down registration and hopefully you'll be able to adjust that and still have a clear view.

The part has a "-02" suffix so it's not the original rev, but it's not on the 6th(?) like the center console. We need more data to know what was originally shipping.
 
I was about to start a separate thread, but this discussion and everyone’s responses have been extremely helpful.

We’ve had our Gravity GT for about three weeks and still haven’t been able to use the HUD effectively. The image is unclear, the brightness and position adjustments appear nonfunctional, and it sits too low for an average-height driver.

Mobile Service advised that they weren’t authorized to investigate HUD concerns and recommended a visit to a service center. We live near the SC/NC border, so Roswell appears to be our closest service center.

Has anyone had their HUD successfully diagnosed or repaired there? Is there a particular service advisor or technician you’d recommend?

On the forum there are I guess two cases I have read that HUD got fixed.

Thank you!
Do you recall whether either of those repairs was performed at the Roswell Service Center? Also, my understanding is that the successful fixes required replacing the HUD hardware. Is that what you gathered as well?
