Inner Navigation > The Cologne turnaround
LX/2002
Situation: Cologne, Germanycoming from Ostende, Belgium
Traveling during the night
Result:

Situation: Jonsson arrives at night, after he was sleeping he thinks he arrives like this:

Why this example?
LX/2002
• People are normally shy in telling these kind of
stories.
• This experience points out that humans must have
a "direction sense" that we are not aware of.
• It also points out that we have a kind of inner
compass (that is influenced by for example
fatigue, age, alcohol)
![Page 9: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/9.jpg)
Spatial system
LX/2002
When we first explore an area, we make a cognitive
map of it.
A map that guides us on later visits. This takes place
automatically, we are not truly aware of what is
going on.
Imagine the following scenario
>>>
![Page 10: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/10.jpg)
Scenario
LX/2002
We have to design a workable spatial system
for human beings.
The information has to be very simple
It also has to be very fast
![Page 11: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/11.jpg)
Scenario
LX/2002
If our shelter were hidden from our view, we
had to be able to ´see´ exactly where it was:
Either the hill has to be
transparent for our mind’s eye, or
We had to be able to mentally lift
ourselves high enough to see the
shelter behind the hill
![Page 12: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/12.jpg)
But there is more...
LX/2002
We have to recognize it without delay and fail;
That rules out the top vertical view.
Today it’s hard to imagine that a map can look
any other way…
![Page 13: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/13.jpg)

Situation:
LX/2002
The correct direction to properly
oriented objects seen from the side
But...direction is from here to there
If the here is
unknown, the
direction cannot
be know!
Direction Monitoring System (Inner compass)

Spatial system
LX/2002
We know where we want to go, and how the shelter looks.
Now we need to know where we are.

LX/2002
Imagine that you are on a
city street that you know
very well.
Then you obviously know
where you are. But how
do you know that?
Cognitive maps
![Page 18: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/18.jpg)
Cognitive maps
LX/2002
You know where you are because it is all in
the map in your head, the cognitive map.
But looking at this map is not easy. Part of the
difficulty is the label map
Better would be to call it:
Awareness of our familiar environment
![Page 19: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/19.jpg)
LX/2002
You recognize the
landmarks around you.
But…
On your cognitive map you
can also see around the
corner.
Cognitive maps

LX/2002
Around the corner:
Awareness of our
familiar
environment

Where does it come
from? >>>

Cognitive maps
LX/2002
We don´t tell ourselves, this is a new place, I
have to make a good mental map to use
when I come back in the future.
Our natural curiosity…
When are we confused??? 3 examples >>>

LX/2002
Example 3 > EXPO 98
North must be towards the top of the map. Always.
![Page 26: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/26.jpg)
Always?

We rely on outstanding features like the ocean or mountains.
EXPO has the tower and the river.

Parking lots
LX/2002
Living in an urban environment is easy
(if you know how to read…)
There is one situation where we need our
spatial system:
Finding our car in a parking lot.
![Page 29: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/29.jpg)
Parking lots
LX/2002
Complex situation:
Large shoppincentres(Colombo, Vasco da Gama, Forum Almada)
Most of the time we manage to find our car.
How?
When does it go wrong?
![Page 30: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/30.jpg)
Parking lots
LX/2002
When we enter we make a map, our car is the
most interesting object.
Problems:
Wrong car
Wrong floor
Changing context
Solutions: colors, animals, marked billet
![Page 31: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/31.jpg)
The Expedition (hiking and holiday)
LX/2002
No distance (topographic vs cognitive map)
Norway Tourist Association example:
Lines between huts where trails exist, showing hours of hiking needed with ´normally fast walk without rest´.
Since all the trails are well marked, with signposts at every junction, this little slip of paper is all the tourists need.
![Page 32: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/32.jpg)
The Expedition (hiking and holiday)
LX/2002
Holiday > Memorabilia > Pictures
![Page 33: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/33.jpg)
The Expedition (hiking and holiday)
LX/2002
This chemistry is only
possible when you
actually visited the
place.
Otherwise you see just
the picture...
![Page 34: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/34.jpg)
The San Francisco Effect
LX/2002
Misorientation can vary in strength
The stronger our spatial ability, the stronger
the illusion
Our direction frame has the tendency to rely
on outstanding landmarks
![Page 35: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/35.jpg)
LX/2002
Dominant surroundings
come from a
direction frame
during childhood
How did a handicap like
this survived the
evolution?

Navigation on the Desktop
LX/2002
• The problems with metaphors• Bob software
![Page 37: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/37.jpg)
Navigation on the Desktop
LX/2002
• Making information (the invisible) visible
• Interface could be anything(house, factory, movie, etc)
• Story from PARC is now familiar
![Page 38: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/38.jpg)
Navigation on the Desktop
LX/2002
• The original idea was limited (different windows on monitor)
• Alan Kay´s solution was to regard the screen as a desk
• It wasn´t very convincing, but the metaphor was NOT an attempt to simulate real world...
![Page 39: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/39.jpg)
Navigation on the Desktop
LX/2002
• The triumph of Microsoft Windows confirmed the basic value of the graphic interface.
• But there are limitations that come from being too faithful to the original metaphor itself
(Extending the original desktop into more fully 3D spaces, into office buildings and living rooms)
![Page 40: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/40.jpg)
BOB software

• A living room on every desktop!
• Based on General Magic´s 1994 operating system for handheld computers

BOB software (brainstorm interlude)
LX/2002
• People are visual creatures. If we would have a 3D view of the computer world, life would be simple!
![Page 44: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/44.jpg)
BOB software (brainstorm interlude)
LX/2002
• People remember where on the page they have read a thought, where in the office they have placed a book.
If we could provide the same 3D facility to computers, interface problems would be solved.
![Page 45: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/45.jpg)
BOB software
LX/2002
Wrong…
• Vision versus Space• Our spatial abilities are
overstated(good, not perfect, individual differences)
• It is not 3D, but a picture of 3D(In 3D world I loose things; here not)
![Page 46: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/46.jpg)
BOB software
LX/2002
Wrong…
• BOB is the living room• And also a clean Walt Disney
World(User friendly? Yes! But who wants a friend like that)
• No social interaction with persons(Strange in a networked world)
![Page 47: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/47.jpg)
Metaphors (Final thought)
LX/2002
• Is a metaphor always wrong?(If it´s not the same, how can it help you?)
• Importance of the difference(Windows versus Windows)
• Does it help you understanding?
![Page 48: Inner Navigation](https://reader033.vdocuments.mx/reader033/viewer/2022061300/54c7b2094a795995658b4591/html5/thumbnails/48.jpg)
