The other paper I showed was always public over a decade before.

Unfortunately, I cannot access the paper and as such cannot give any meaningful feedback. Edit: Funnily enough, searching on google for this paper, your comment is the second result.

As an aside, wanting me to pay $33 to read a PDF of a paper from 46 years ago is... unfortunate. (I have a list of other words I'd rather use, but I'm being civil)

This is one of the reasons why I think patents are important, because it allows them to profit from their inventions, and for the inventions to be reused later by others, even if the product was "too soon". They invented innovative technology, tried to build a real product, they should be able to make some money from others picking up the baton -- and presumably they did, when they sold the company through the chain…

I couldn't disagree more. If you try to build a commercial product and fail that doesn't entitle you to the profits made by others who made a successful product.

If the successful commercial product is based on the research of someone else, why does building a commercial product that succeeds entitle you to the innovations of others? I tend to favor liberalizing intellectual property, but your lens seems to suggest that value exists only in commercial success which ... is odd.

That sounds fascinating, but it's not really clear to me how imagining islands beyond the horizon can help with dead reckoning. Maybe there are changes in observable phenomena, such as ocean currents, that are associated with these unseen islands? It does sound like a very complex system based on the beginning of this article; I'm wondering if anyone here has read the books mentioned in it: https://www.jstor.org/stab…

Yeah, this surprised me as well. I get how reading ocean swells, sea life, birds, ocean color (indicating depth and/or plant life below) could give a general sense of position. And I can see how stars, prevailing currents and maybe even estimates based on the relative movement of clouds (adjusted for ambient wind direction and weather conditions) could give a general sense of distance traveled. But on a completely cl…

> I'm not sure how the concept of tracking virtual islands over the horizon really helps. The only thing I can think of is maybe the idea of it encourages the navigator to stay focused on estimating the passage of proxy points on the far horizon

You can practice navagating against physical islands over the horizon, and when you're good at that, you've mostly gotten good at dead reckoning against a real reference point; of course, with corrections from the islands influence. Having a community shared archipelego of virtual islands lets you focus your dead reckoning skills on a point while offering a vocabulary of distance and reducing travel times between waypoints.

Go 1000 miles in this direction seems a lot harder for me to follow over many days than go X miles to A, then Y miles to B, then Z miles to C. Even if A and B aren't real. If I treat them as very small islands that will be over the horizon, no big deal that they don't influence the environment, they're small; but I can't really use them to course correct, my reckoning needs to be good.

I think the problem comes when the correct solution is so obvious that it can be seen years in advance and it becomes a race to see who can patent the obvious solution first before the tech catches up and people start actually building it.

This is why people were mad at the "email, but on a cell phone!" patents and all of the "doing thing companies were already doing, but with internet!" patents from entities that don't make a product so they don't have to deal with real world limitations. Once the actual manufacturers start working on the problem they discover all of the obvious solutions locked behind patent walls.

> I concur with you that Etak delivered a functional product, albeit not a commercially successful one, which is farther along than Jodorowsky's Dune project, which stalled mid-way in development. You seem to be responding to another comment? Or are putting words in the commenters’ mouth?

I was responding to the "Jodorowsky’s attempt was ... never released" critique by trying to expand on both the similarities and dissimilarities between Etak and Jodorowsky's Dune.

My comment wasn't really about Etak at all, I just thought you might have mixed up Jodorowsky's Dune with Lynch's! The Lynch one seemed like a better fit, although I think "set up an entire field for subsequent success" is a bit of a stretch for both of them.

1991 home video demo of an Etak, in a custom housing: https://www.youtube.com/watch?v=CHCCjlSWbHE?t=1m50s (Bet they didn't think at the time that techies of the future would be watching it in 2024 on the ubiquitous global data network.)

I just love the look of vector displays and I wish they were more common still today. Such a cool aesthetic!

Me too. Atari, toward the end, had even mastered color vector displays that look excellent!

Look for clips of "Star Wars" in action.

The 70's was anni interesting time. Atari was employing dynamic vector displays capable of real time motion.

Tektronix was using vectors with their storage CRT tech. Basically the vectors got painted onto the tube phosphors, thus displaying the image without the need to refresh.

4k resolution (vector coordinate space) ended up being a thing!

Bosch EVA (1983) "The prototype driver navigation system was unveiled in Hildesheim on June 21, 1983, and it proved groundbreaking: EVA was the first ever experimental autonomous navigation system." https://www.bosch.com/stories/eva-first-navigation-system-fr... (no map, but display and address to address with route finding)

I wonder what was the state of navigation systems for planes at this time, because among the car GPS brands, one finds for instance Garmin, which is an avionics company.
