I have a HUD in my car that shows me directions, speed etc and when I'm looking at that the rest of the view out the windscreen is hardly even there to my visual perception even though I'm looking right at it. This seems to be getting largely overlooked but I feel like over time statistics are going to emerge that HUD type displays are increasing accidents rather than preventing them.
Your car might have settings to adjust it somehow, have you tried those?
I recently hired a car where I had to duck under the steering wheel to check my speed!
wahhhh? is this real life.
Here in the future we use our thoughts.
Airplane HUDs occupy center of the vision, literally showing where you're going. Car HUDs don't, and instead stay out of sight, as it's illegal to do in cars what they do in planes. That makes car HUDs just heads down display that happens to be transparent.
But it’s uncomfortable for me because it requires my eyes to refocus from distant to close and back when I glance at it, which isn’t needed with an actual mirror. So I don’t use the feature.
I found myself actually using the incidental reflection on the surface of the screen instead of the actual pixels. I can't believe this arrangement is legal.
There are ways to do stuff like this.
Though I don't feel comfortable having more Meta in my life.
And, yes, surely, one needs to periodically switch attention to mirrors and instruments, and I must imagine that shorter gaze movement distance shouldn't hurt. It's the same as checking the speedometer - you don't see the road, only have a rough idea from the peripheral vision.
Although I can imagine that a HUD can be actively distracting, constantly intercepting attention, e.g., flickering.
It doesn't display notifications or other distractions, nor is it possible to configure it to do so.
It's not flickering when viewed in person, but when filmed with a phone camera they do flicker due to how the display works.
It's a pretty good system, and allows one to keep their eyes on the road without having to look at other screens, and keeping ones eyes focused on far objects.
With a normal car dashboard, you're much more aware you're not seeing the road while checking your speed, and you don't actually see the speedometer moving while you're looking at the road, so it can't accidentally catch your attention.
Of course, none of this will matter in the vast majority of cases. But driving safety is all about the tail end, when you're slightly tired or when someone in front of you does something unexpected and maybe illegal, or someone jumps on the road - these are the times where accidents are avoided, and a HUD might well hurt rather than help for these cases.
In fighter jets, they project onto the visor. Obviously not the most convenient method for an automobile. There have been attemtps to figure out depth of field but it's tough. https://www.sciencedirect.com/science/article/abs/pii/S00304...
Don't, and I mean DON'T decide things for the user.
Extreme example: showing random ads every ten minutes, even if the glasses c/should suspect you’re driving a car. I have my doubts as to whether Meta will make the right choices here.
Your attention reacts differently
As in, are you just concentrating on the speedometer instead of the road, or do your eyeballs have to adjust because the optics aren't set correctly? I believe a HUD is supposed to focus at infinity, same as a road that's many times farther away than the size of your eyeballs.
It's pretty interesting how today's cars come with features like remote braking and monitoring cameras, all designed to make driving less demanding for us. So as these researchers work to make vehicles less distracting, these cool features somehow end up making us even more distracted. It's an ironic cycle that leaves you more distracted, and maybe more unsafe.
