This might not be unique to presidential speeches, but it’s where I’ve seen these things.

It's like planes & cars with HUDs on transparent windshields (only the driver can really see it):

[–] Th3D3k0y@lemmy.world 15 points 1 day ago (2 children)

I'm not sure why more cars don't do this, it seems almost all upsides.

[–] Evil_Shrubbery@thelemmy.club 10 points 1 day ago* (last edited 1 day ago) (1 children)

Exactly.

This is tech from the 50s (and you can find concept pics of it used in cars), it's simple, cheap, and improves road safety a lot. I struggle when I have to drive a car without hud (I've first seen it irl around I guess 2005, yet not much changed till today, you still either have to pay extra or buy one of the top specs). Govs should just mandate it as a standard.

Even weirder, when talking to ppl irl they mostly just say "oh that's stupid" or "I don't need that" (my father used to be one of those ppl too, and when he recently took his car to the shop & they gave him a temporary car without hud he bitched about it all the time how he doesn't know how fast he is going (without looking away from the street)).

(There is loads of such tech that work as good as 20 or 30 years ago, are generally cheap in terms of production costs, yet they remain a rarity - adaptive/radar cruise control, adaptive high mean beams, self-levelling low beams, cornering lights, IR cameras spotting & beaming nearby pedestrians and animals, etc. At least EU mandated assisted emergency braking so that the crashes occur at lower speeds or not at all. Megacorps just have to much influence/power/profits.)

Nissan Silvia & 240 used this basic hud in 1988:

Oldsmobile, also 1988:

[–] captainlezbian@lemmy.world 3 points 1 day ago (1 children)

My father had a car with that when I was a kid and I still remember how much he loved it.

As someone who's never had it it's always seemed like a nice to have and like it's silly it's not standard. Though it does look like you can get aftermarket ones at a reasonable price and that is tempting

[–] Evil_Shrubbery@thelemmy.club 1 points 1 day ago* (last edited 1 day ago)

On my first car I used my phone for that (some Symbian Nokia maybe?), but only a few times.

It didn't have the battery for it really, and a bit of lag on them old GPS dedicated chips (it fit the dashboard nicely tho), but it proved the concept beautifully.

[–] SaveTheTuaHawk@lemmy.ca 3 points 1 day ago

Because Elon wants to kill you.

[–] triptrapper@lemmy.world 118 points 2 days ago

Yes. They project the text from an angle so it reflects towards the speaker. Just like windows are transparent but can still reflect images in the right lighting.

[–] AbouBenAdhem@lemmy.world 48 points 2 days ago (1 children)

They’re teleprompters crossed with Pepper’s ghost.

[–] starman2112@sh.itjust.works 22 points 2 days ago (2 children)

Are you telling me these teleprompters are haunted

[–] HobbitFoot@thelemmy.club 6 points 1 day ago

Any reasonable person would know they are haunted.

Nothing beats el fantasma teleprónter caliente!

[–] zikzak025@lemmy.world 27 points 2 days ago (1 children)

Yeah, they're still reflective enough to mirror the text when viewed from the right angle.

Here's an example from YouTube so you can see what it looks like from the perspective of the one speaking:

[–] Steve@startrek.website 6 points 2 days ago (3 children)

What a shit demonstration. 1 second in the middle shows how it works, the rest is some guy talking.

[–] SaveTheTuaHawk@lemmy.ca 3 points 1 day ago (1 children)

So....like every youtube video.

[–] Steve@startrek.website 1 points 1 day ago

Every demo or build video should start with the money shot, then go back to step 1.

[–] g0d0fm15ch13f@lemmy.world 9 points 2 days ago* (last edited 2 days ago) (1 children)

Try this one, this guy is great about getting into the nitty gritty. https://youtu.be/YeRu4xYH_W0

[–] Passerby6497@lemmy.world 4 points 1 day ago

From the teeny thumbnail, I can tell that's Technology Connections, and Alex is great for deep dives into random bits of tech.

Anyone interested in pinball machines can find a 3 part series on them, and its sooooo much fun to watch

[–] zikzak025@lemmy.world 3 points 2 days ago

Yeah I didn't look that hard, was the first video I found that was sub 3 minutes. They're all just marketing reels, no one else seems inclined to just upload a quick video on how teleprompters work.

[–] Rhynoplaz@lemmy.world 5 points 2 days ago (3 children)

Are they actually teleprompters, or are those mirrors that reflect the teleprompter screen below it?

I've always wondered.

[–] 4am@lemmy.zip 9 points 2 days ago

They reflect the screen below it, so that the audience can see the speaker even if the prompter is in the way; they are part of the teleprompter.

The screen shows all the text backwards since it’ll be reversed in the mirrored image, so you need both for it to work.

[–] Onomatopoeia@lemmy.cafe 6 points 2 days ago

One and the same.

[–] Linktank@lemmy.today 48 points 2 days ago (3 children)

Dude has teleprompters and still sounds like a complete moron. Sad. Everybody is saying it.

[–] aev_software@programming.dev 17 points 2 days ago (1 children)

Everybody knows! Ask anyone!

[–] Linktank@lemmy.today 13 points 2 days ago (2 children)

Seth Meyers making fun of him from transitioning from one teleprompter to the next is one of the funnier things I've seen online lately.

[–] XeroxCool@lemmy.world 5 points 2 days ago

After the 10 min mark for the teleprompter switch, for anyone who can't spare 15 mins in their hour of scrolling

[–] JetpackJackson@feddit.org 3 points 2 days ago

Thanks for the laughs, kind stranger

[–] mastertigurius@lemmy.world 13 points 2 days ago

The teleprompters are just for show so that it looks like he can read

[–] yermaw@sh.itjust.works 3 points 2 days ago

Cant get real and go off-script if there's no script to go off of.

[–] zikzak025@lemmy.world 30 points 2 days ago

Teleprompter. They're mirrored on one side and reflect a screen with a script scrolling below them.

[–] Zier@fedia.io 13 points 2 days ago

It's the secret portal that lets the aliens control the heads of state.

[–] Typotyper@sh.itjust.works 12 points 2 days ago (2 children)

Hologram projectors. Only true way to protect the president is to hide him

[–] captainlezbian@lemmy.world 1 points 1 day ago

Ok honestly though, if i were the president I would troll the country by appearing as pepper's ghost at some point…

[–] lagoon8622@sh.itjust.works 3 points 2 days ago

They project a visual effect on it that makes it look vaguely humanoid

[–] BennyInc@feddit.org 6 points 2 days ago (1 children)

It’s bulletproof glass for the two small blind spots the Secret Service can’t cover. They tried different agent setups to cover all sides first, but eventually figured „ah, fuck it, let’s just put some bullet proof glass on these two angles and we’re fine.“ Also, they have a secondary use to project text for the president to read. But that only came up after Obama came up with idea. „Hey guys, why don’t you project the text I need to read somewhere in the wall, so I don’t have to use a stack of papers?“ - „but isn’t that too far away to read?“ - „ oh, yeah… hey, how about we use that bullet proof glass thingy and project it on there?“ - „seriously? Projecting onto glass? What did they put in your cereal this morning, sir?“

[–] LittleBorat3@lemmy.world 1 points 2 days ago (2 children)

Maybe this invention saved Trump, that's what makes it an evil invention

[–] Hermit_Lailoken@lemmy.world 3 points 1 day ago

Poor aim is guilty of saving Dump.

[–] SaveTheTuaHawk@lemmy.ca 1 points 1 day ago

Why does Trump need a teleprompter? You mean the battery boat shark speech was from a Harvard English grad?
