He just lists two failed smart helmet startups, then talks about a successful smart helmet that doesn't use a full HUD but uses an LED light bar. The only actual point he makes is that it's hard to make a display that's visible in the sun.
It's also a motor cycle channel so he makes points like "why not use your mirrors or built in dash" which is not really applicable to cyclists, eskaters, EUC users, etc.
Fair reasoning but I still think Ryan is in the right path.
He is right that shoving a holographic display and the computer bits in the helmet either makes it bulky, heavy, and useless or you'd be paying up the wazoo for what is an engineering exercise.
A simpler interface that solves current problems in my opinion would be much better than trying to make an Ironman helmet.
It’s very dangerous to focus your vision four inches in front of your face while driving. It also takes a second to switch from distance vision to being focused so close, which undermines the whole “at a glance” value of a HUD. Race cars have instrument panels pushed as far away from the driver’s face as possible to make the focal length changes inside your eye easier and faster to switch between. A helmet HUD is the extreme opposite of that.
That is not an issue with anything that is supposed to act as a HUD, as they project the image in such a way that it looks to be further away. They have to, because humans are terrible at looking at something that close to their eyes anyway.
Google Glass for example projected it so that the image looked like it was 2.5 meters away from your face.
I'm really curious what the Google Glass concept would be like with modern technology. I feel like the form factor was poisoned from the backlash at the time, but it seems so much more viable than the stupid bulky headsets.
Lensing. BMW HUDs bounce off a few curved mirrors before reflecting off the windshield so some key details appear 30ft in front of the car. Meanwhile, VR goggles have the screen unfocusably close but due to lenses inside, objects can appear any distance away (and it's not just parallax, there's near and far focus)
My Cadillac has a video display as a rear view mirror and it has that issue. With a traditional rear view mirror your focal length doesn't change much, but in my car your focus has to shift to the mirror 2 feet away.
It has upsides though, as passengers or objects in the rear seat don't affect your mirror view.
Whenever I change vehicles it takes a few minutes to readjust.
What if the helmet had a camera that projected it's view along with the hud? You might lose some depth perception but at least you could see the road while looking at the HUD.
I'm pretty sure there are a couple motorcycle helmets out there with a built in HUD. There are after market ones that you can add to your existing helmet that seem pretty cool to.
There's also the Cross Helmet but I'm super skeptical. Not only are helmets limited-time use, so after a few years it's trash anyway. But that seems like it would be super distracting for something that requires your utmost attention.
If I start seeing racers (or some other riding professional) wear them, I might consider it.
That's cool as hell but $500 is about what I'm willing to spend on an entire helmet not just an attachment. I suppose I'll keep dreaming. Thank you for showing me that though.
a HUD would be more in your field of vision in terms of the X and Y dimensions, but in the Z dimension, depth, in the worst place of all.
Focusing your eyes an inch away from your face is, unfortunately, taking your eyes off the road. The closer something is to you, the greater and greater focal length change is required. Switching between road vision and 1-inch off your face is much much harder than switching between road vision and 24-inches away from your face (where conventional speed dials are, on the handlebars).
It’s not just about the time and effort it takes to do this. When your eyes are focused 1inch away, everything on the road will be super blurry. When your eyes are focused 24 inches away, the road will not be as blurry, and it’s easier for your eyes to jump back onto the road.
I dunno, if you're relying on a number to determine if you are proceeding at a safe speed, I am a bit skeptical you have sufficient mastery of whatever motor vehicle you are operating.
Just as if you're relying on a speed limit sign & law enforcement to control what speed drivers go rather than road design feedback, you have insufficient mastery of your engineering trade.
