Wayfinding: The Science and Mystery of How Humans Navigate the World

Post by jennypenny » Tue Aug 27, 2019 11:06 am

Reviews on Goodreads here.

It was pretty good. It might be worth a read because it addresses the acquisition and usefulness of navigation skills and how our brains might rely on them to stay sharp as we age. Navigation (place orientation w/o electronic assistance) might be one of those skills that has more benefits than we realized.

I'll admit though I'm predisposed to like any book that justifies my parenting style of kicking my kids outside and sending them off into the world on their own. :P

NPR podcast with the author.

Interesting. I've long railed against gps for just this reason.

When we were in Jordan we had a car for a month and couldn't find a good paper map of the country. I wasn't too worried since there aren't many roads and I had gps on my phone. We ended up using google maps with voice directions the entire time since many of the road signs were in Arabic. It has been three months now and I am unable to remember all but the major routes we took in Jordan.

Strangely, I can vividly remember routes we followed though Africa 18 years ago. I can also remember things like smells and colors and changes in geology and different people from Africa whereas Jordan seems much flatter.

I've been puzzling out why. Every morning in Africa we would pour over the maps, anticipate turns and jot down notes. I was alert to changes and intersections and every road sign we passed. I was nervous about getting lost. I was constantly concentrating and often asked directions multiple times in the day.

In Jordan I didn't think at all. I didn't even look at the map. I wasn't nervous, barely looked at road signs, often allowed my mind to wander and never asked for directions.

We won't make that mistake again.

I revisited two point triangulation this week with some friends. I told a story of how I once got hopelessly lost in the Urals and used a map and Suunto compass to triangulate off a radio antenna and a monument to Lenin. I couldn’t read Cyrillic so signs were meaningless.

Some GPS dependent youngster was brave enough to ask, “how do you do that anyway?” We went into the backyard and shot bearings to the local mountains and located ourselves. For a moment I felt like an old guy showing people how to start a fire or flake flint arrow heads. People were interested yet nobody had a clue how to do it. There is a natural desire to know how to do this.

What blew me away even more was another kid asked how exactly GPS worked. We use it all the time but nobody at the party (mostly tech people) actually knew how the satellites do absolute location. People made up a lot of imaginary methods though. “They broadcast latitude and longitude”. :lol: Back in 1800 I think navigators knew exactly what their sextant, chart and clock did, beside how to use it.

I imagine that the same benefits (a well connected hippocampus) can be achieved by navigating spaces other than the surface of earth. Games with an open world (Skyrim, WoW, Minecraft, and so forth) are much easier with strong spatial skills. One major difference is that these are all disconnected, so perhaps this allows the brain to more easily compartmentalize such spaces and their associations. Overtime, lack of playing could disassociate them in the mind.

I can still remember the blueprint or structural layout of every(?) building I have been in from a very young age (in the hundreds). I can also remember 30+ Call of Duty maps, and several other maps I encountered in various games from the ages of 12-17. I have to focus for a couple minutes to bring them into my awareness, but they seem to still be quite vivid even after a few years. Even the internet can be projected onto a topology for easier recall. My current hypothesis is that types with third slot Si do not have much control over what they remember, but they tend to have extremely good memories for particular data structures. Si in the first or second slot would tend to remember a wider variety of information. I typically cannot remember names or dates very well even if I try, but I was born with an affinity for efficiently encoding certain forms of spatial information.

(?) It is probable that locations have been disassociated to the point that I cannot find a path back to them.

Recently, I have been playing GeoGuessr where you are placed somewhere on Google Street View. The objective of the game is to pinpoint your location using any cues available at your disposal (signs, languages, street markings, cars, side of road, foliage, sun position, people, markets, and much more). This seems like a good exercise if you do not want to spend money or energy traveling. Going on a walk every day is another low-cost hippocampus exercise.

It is also worth mentioning that all of the so-called extreme feats of memory are done using the method of loci. Information can be encoded into a dictionary-like data structure where the key is a list of either real or fictional locations.

Location is always relative to a reference point:)
Finding out how GPS (or GLONASS or Galileo or whatever the Chinese version is called) really works is worth spending an evening or two finding out. I thought I had a pretty good idea, but was recently given a challenge (by a teacher!) to make sure. It was nothing like I'd assumed and imagined. The next few evenings were spent with biographies of Einstein and Doppler. Really fascinating (GPS technology, not so much the biographies...)

Daylen you bring up a good point. I’m not a big fan of games and it’s commonly warned that they remap the brain. But I’m sure there are some areas like those you mention where your brain can be strengthened especially given the repetition of gaming.

I can barely remember the last time I was hopelessly lost in real life. I don’t wander in the wilderness anymore nor do I travel much outside familiar places. And when I do, I use GPS and go blind so to speak. It’s funny how you lose all concept of scale and all distances get judged by time of travel rather than passing landmarks.

Come to think of it the last time I wandered hopelessly lost was in a computer game.

Seems like just another type bias. The Ne-Si axis can be quite unsettling/disorienting for many. I am fairly sure that my gaming background helped me develop a more creative outlook in life. All the rule sets, maps, simulations, and real-time optimization schemes have been abstracted away into an intermediate layer in my mind and mingled with mathematics. Engaging with many separate realities aids the kind of imagination required for constructing mathematical arguments and solving novel problems.

Sort of relates to the other thread on employ-ability. My motto is more along the lines of play first, then figure out how to gain an advantage later when needed. Though, it is probably more challenging to maintain sanity this way.

In practical terms, I think this is a very good description of what happens when you use navigation tech instead of finding your way.

I didn't know this until just now when I went on a Wikipedia binge: Atrophy of the hippocampus is linked to MDD (major depressive disorder). More people are depressed now than ever before. I have no idea if there is any causal direction or hidden factors influencing such correlations, but the connection seems relevant to this thread.

I love this on so many levels but mostly just the geeky effects of mass on space and time:

I love this subject as I used to head up a search and rescue team for a volunteer dept. Honestly, with the right mapping program, a GPS unit, a paper copy of the region being searched, a compass, a pencil, and a grid tool it is very hard to get lost. Even if the GPS dies along with the computerized mapping program. The key is to have the proper map before you start the journey. We used TerrainNavigatorPro for the mapping and switched our GPS units to UTM (universal transverse mercator). With this system it is almost impossible to get lost or not know where your guys are in the field.

I learned all of this stuff after we had to search for a lost hunter experiencing chest pains and to be honest it was a clusterfuck, although we did find him eventually. We had teams all over the place with no idea where they had searched or if they even knew where they were when they radioed back to us in command. It was a mess, and the guy was saved, but man did we waste a lot of energy and time finding him.

What is also interesting are the case studies of people that get lost. Almost all of them if they decide to walk out eventually create a circle if they don't have the training to overcome this:

Look at his route on foot:

The book we followed when searching:

One of the things you figure out fast is that the simple answer is usually the right one. And that dogs are hit and miss. I was never all that impressed with the dog's performance, but it could have been a dog handlers issue as well.
