Consumer GPS navigation aids are pretty good for getting from one town to another. But they are somewhat less useful for pedestrians, the accuracy of the mapping being on a fairly large scale - fine for vehicles, but less good for those on foot, particulalry those who are driven by a combination of a
thirst for accuracy and extreme laziness.
Most people have no doubt wondered, when making a journey on foot where several routes are available, about how to work out the most efficient path. Down the main street and then left ? Up that side street, across the car park and then through the alley ? Cross the road by the pub, or down by the traffic lights ? And of course, one must factor in the variations in elevation over the route ...
With the new BorgCo advanced GPS, your doubts are soothed. On the generously-sized colour LCD display, you will find a dynamically updated map and instructions that tells you with millimetric accuracy whether to walk on the sunny side of the street, or not, as appropriate.

I don't know if there is a way to upload directions to a GPS, but this would be close to what you want. [Klaatu, Apr 29 2010]

Oh dear. [8th of 7, Feb 12 2012]

//How does your device create this milimetric accuracy?// |
|
| |
By using the Galileo positioning system, rather than shitty
GPS...? |
|
| |
Okay [8th], I batted that one away for you- but the follow up
is worse: what's new here? I mean, [21Q] has a point in that
you don't say why this would be technically better than GPS
and [Klaatu] points out that there are pedestrian uses of GPS. |
|

//whether to walk on the sunny side of the street//
<sound of penny dropping> |
|

Ah! The niche that you're aiming is the topology graph.
Someone has to input the street coordinates to create a
mapping to location coordinates. There aren't 'cut corners'
approaches - Google maps doesn't calculate my pedestrian
route with an allowance to walk across a football field, for
instance.
So topological detail is the real innovation.
Accuracy is needed, but it's not the main point of the idea. |
|
| |
Yeah, I've been given directions down the length of the UK
that went across the Irish Sea, instead of the perfectly good
roads. Google's point topology and their sorting algorithm are
not %100 by any means. That kind of thing is an artefact of
their system - not a short-cut! |
|
| |
[Jinbish], yes - topology to a very high accuracy, much better than the crude WSGS84 geoid; and the path is optimised using curves, corners, diagonals - anything to save a slightest bit of physical effort. |
|

[Ian] Whilst not wanting to get too 'zen' about it, obstacles are only in your path because you're focussing on them. Literally, I mean. If you walk towards a seething crowd of people and avoid any sort of eye contact by maintaining a steady focus on a point about 20 metres behind the crowd which you walk straight towards, you'll find that the crowd will magically part and allow you through. Try it - it works. |

//future of badly structured clusters of slow and clueless tourists.// |
|
| |
Ok - so we need some combined P2P Bluetooth & GPS location & path analysis to start generating the "best route". |
|
| |
Or take [hippo]'s approach. To use a sporting cliché: it's about who (w)ants it more! |
|
| |
...or any other kind of insect - it's not just confined to ants. |
|
| |
[hippo], now leave your ripped black combat outfit and large axe at home and try it again. |
|
| |
I've been plagued by typos recently. Sorry guys. |
|
| |
Condition of street lighting and local crime figures might be a useful addition . |

It's good to see Ian in a good mood for a change. (I
for one enjoy his descriptions, they are what I'm
thinking, usually, just don't say.) |
|
| |
[one big hand waving at Klaatu and his link]...!!! |
|
| |
Yeah, it was easy enough for Aurelius to say that: his name wasn't forgotten. The poor sap that he said that to, however, is just nameless dust and bones... |
|
| |
One out of two ain't bad ... |
|
| |
[Ian] - glad to see you didn't let it affect you too much |
|
| |
Indeed, [IT] is clearly in touch with his inner Tourette's Sufferer ... |
|
| |
Soooo, how are we feeling today Mr Tindale? |
|
| |
[Ian] you don't by any chance happen to work for the
same employer as your present interlocutor, do you?
Only I recognise the symptoms. |
