Are Sat-Nav Systems Becoming Information Overload?
curtS writes "The Economist's tech editor reviews the ever-more-detailed assistance of mobile GPS devices, and wonders if the attention-sucking visual complexity isn't more trouble than it's worth. He contrasts the simplicity of London's Underground map (not directionally accurate but visually easy to understand) and his own habit of dimming the display and using the audio commands for guidance."
My car's frontwindow angle is say 45.
This allows me to just put my Android phone on my dashboard which reflects on the window and generates a transparent reflection which shows up in a "virtual distance" in my field of view.
It's not as crisp to actually read while driving or being stuck in traffic and it requires low light conditions, though. But you can make up a map easily.
I think we can keep recursing like this until someone returns 1
The problem isn't struggling with the GPS(at least not in the sense of "Oh noes, the UI is just too hard!). The question is whether or not the GPS UI is distracting the driver's attention enough to make them especially vulnerable to doing stupid(which in a car means dangerous) things.
Research consistently demonstrates that humans suck at multitasking. Worse, they suck at multitasking to a much greater degree than they think they do. If interpreting a poorly designed GPS UI while also driving counts as multitasking, it is probably a dangerous distraction. If the GPS UI is well designed, it could presumably function as just another subtle environmental cue, something that humans are very good at interpreting.
Reminds me of this.
"Since a road closure, dozens of drivers have blithely followed directions from their satellite navigation systems, not realising that the recommended route goes through the ford.
Normally the water — the start of the River Avon — is about 2ft deep but it can swiftly double in depth after heavy rain.
Every day since the main B4040 was closed after a wall collapsed on April 8 one or two motorists have been towed out, having either failed to notice or ignored warning signs. Some farmers have been charging £25 to give a tow with tractors."
I have to post quickly, I have a Prius with a technology editor pinned inside I need to unwrap from around a bridge abutment.
Most people have pretty poor situational awareness. I've overheard more than once on he local ham radio repeater a conversation similar to this:
Ham driver: "Help help I have an emergency, I need a phone patch to CHP!"
Ham answers from somewhere: "Where are you?"
Driver: "I'm on the freeway!"
And so on. I can only imagine what 911 dispatchers go through.
Give a man a fish and you have fed him for today. Teach a man to fish, and he'll say "WHERE'S MY FISH, YOU IDIOT?"
Wait, isn't sucking at multitasking already multitasking, right there?

If the guy is a technology editor, why is he struggling with something as simple as a GPS? I'd understand if he was reporting that others had this problem... but come on.
Ah, I believe the point being brought here is not a matter of being technologically challenged by such a device, but more of the matter of being a device that has gone from being a simple GPS to the new "all-in-wonder" device in the car that will talk to you, answer your phone, play music, give directions, and (soon), start throwing advertisements for local businesses in the area, all at the VERY HIGH cost of distracting the person who is in charge of controlling 2 metric tons of steel down a road at 60MPH or faster.
As the death tolls rise every day with cellular use while driving(including texting), I can definitely see the issue with similar devices. When insurance companies start refusing to pay for accidents caused by these devices, THEN we may start seeing some REAL reform with all of this. Until then, watch your ass on the roads, because these next-generation twit(ters) can't seem to get enough distractions behind the wheel. I'll be lucky if my kids live to see 30.
Just last week, here, we had a truck driver following his GPS ignore no less than EIGHT road signs saying "no trucks allowed" ...
Then he got stuck on the train tracks (which was WHY the signs said "no trucks allowed") ... the predictable result followed, and about 24,000 lbs of pizza ingredients got scattered over a fairly good chunk of town.
There are some people in the world who just shouldn't abandon paper.
2 metric tons of steel down a road at 60MPH or faster.
Please don't do that. We've lost mars probes because of things like that.
Yes, but it's only looking at one side of the issue. "Overall, the Carnegie Mellon team concluded that the time drivers spent fixated on their satnav displays decreased sixfold and the number of glances needed to confirm results decreased threefold when the navigation system simply used words and numbers to convey instructions rather than fancy graphics." Fine -- but what did it do to the number of missed turns, or the number of times the driver gets into the wrong lane becuase they don't really understand what the words and numbers are actually telling them to do? They're things that can make drivers "especially vulnerable to doing stupid(which in a car means dangerous) things" too. Most of the time sure, I just listen to my satnav. But at complex junctions, actually seeing the layout and where I'm supposed to end up is invaluable. A picture really can be worth a thousand words.

Or you could do what I do: just take the next exit and let the sat-nav figure out how to get you back on track. If it takes less than a second to do so, missing a couple streets isn't that big a deal, and there's almost certainly a lower attention-demanding route to wherever. Generally, the most complicated places are highways in traffic with left-exits and short spans.
But if you take any nearby exit, there's almost always a "street with many stoplights" that you can pretty much take your time on. Sat-nav also helps with tricky left turns on that street. Just turn right anywhere near your destination and let it recalculate a route for you.
The thing about sat nav is that it creates a new navigation paradigm. If you use it right it can really free you from worrying about where you are so you can concentrate on not hitting things. You don't have to drive straight to your destination without deviating from the route to avoid stopping and getting your bearings. Everywhere is like the areas you're familiar with, where if you miss a turn it's no big deal, you just go one of the other permutations you know all about.
Even if the machine's maps don't quite match up to reality, it's still no worse than when you're in your familiar area and you're trying out a permutation you're fuzzy on: Just turn off when it doesn't match up and get on a route that you know about. As long as you pay attention to the road, the worst thing that can happen is that it'll take longer to get where you're trying to go (unless where you're trying to go is in the middle of a block of roads that the sat-nav is not accurate on. But that's pretty rare.)
Can you be Even More Awesome?!
By the way, just a tip for everyone -- I've found that ironically the bus is actually where a GPS makes the biggest improvement in knowing how to get around.
If you're in an unfamiliar city, buses (in contrast to trains) often have a frustratingly indescribable and unpredictable route/stop pattern, and when the driver/announcement system is of no help, a GPS system in your hand will help you figure out exactly how close you are to your destination, and when to get off the bus.
I no longer dread dealing with buses because of this capability, although the lurching stop/start of buses in general still drives me crazy. Try it sometime -- the small Nuvi-style units are just about as inconspicuous as an ipod, and are great for helping you get around.
But at complex junctions, actually seeing the layout and where I'm supposed to end up is invaluable. A picture really can be worth a thousand words.
Yes, but the columnist's point was that you don't need fancy graphics with photos to tell you that. All you need is a clear diagram.
For those of us who can read maps, sure. But there's something of a sampling bias here on /. -- we tend to be folks who can process symbolic information pretty well. Maps are not a lot of use for my wife, whereas a picture of the intersection with something pointing to where she should leave would be just what she needs.

In May and June this year, I went to Germany and Holland with my father. We rented an Audi with a GPS built in. It was a gift from the gods of navigation. Without it we would have been totally inept, and neither of us had used one before. I generally ran the nav system while he drove (because I picked up the fine points of the system quicker than he did).
One day, in Germany on the Autobahn (can't remember exactly where right now but I do have notes on it) there was a huge traffic jam. I had no idea that traffic there gets like that. But everything was backed up. People shut off their cars and got out to chat. Nobody was moving, in either direction. Remember this is the Autobahn.
Anyway, two notable things happened. We decided to follow a small group of cars that were driving on the shoulder and trying to find a way out. This was probably illegal, but whatever. After getting off the main highway, we wound up alone somewhere. Check the GPS, we found exactly where we were (with the traffic lady letting us know that noone was moving) and it was one a dirt road. I zoomed in on the map, found the next nearest hamlet and we navigated there. Then I did that again and again, and we drove through about a dozen tiny villages. It was amazing. We saw old buildings that no tourist ever sees, and some had scars in them, maybe from WW2. Got to see a lot of neat things.
Later, back on the main highway, we were stopped at a light or something and the kid in the car behind us jumped out, came to my window and asked for directions to some town he was trying to reach. I used the gps and gave him what he needed. That was cool too.
GPS is not distracting. I found it very helpful. Witout it we never would have seen those off-the-beaten path villages.
I found the audio to be distracting, whereas the video display gives me positional awareness, and I can look at it when I choose to, not when the box decides to say something. I found I was much more relaxed when I found how to turn off the audio.
So I guess having both at the same time is the real problem.

I'll see your European anecdote and raise you one. In 2005 I spent 4 weeks driving around Europe with my wife and parents. We had no GPS, but plenty of maps. We were able to find our way into and out of all sorts of out of the way places. The only trouble was trying to meet one cousin where we were waiting on one side of the freeway and he was waiting on the other side.
Now, I've always been good with maps, have a good sense of direction, and a good spacial sense. Not everyone is good with maps or navigating.
On the other hand, often people get their trips too structured. Having a little less structure, a willingness to improvise, and a sense of adventure can result in a really memorable trip.
In your case, the GPS gave you the confidence to get off the beaten path. However if you were just blindly following its directions, you might still be sitting on the autobahn.
