Transcript of Inner Navigation

  • 1. Inner Navigation Xander Roozen/Alta Vision / Lisbon / 2002 why we get lost and how we find our way UX Book discussion about Eric Jonssons Inner Navigation START

2. START > What & Why

  • Disorientation causes stress
  • Urgence
  • Business opportunities

START> outline LX/2002 3. Topics

  • Inner Navigation
  • Navigation on the Desktop

LX/2002 4. Inner Navigation LX/2002

  • The Cologne turnaround
  • Spatial system
  • Cognitive maps
  • Parking lots
  • The Expedition
  • The San Francisco-effect

5. Inner Navigation >The Cologne turnaround LX/2002 Situation: Cologne, Germany coming from Ostende, Belgium Traveling during the night Result: 6. LX/2002 Situation: Jonsson arrives at night, after he was sleeping he thinks he arrives like this: 7. LX/2002 8. 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)

9. 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 >>> 10. Scenario LX/2002 We have to design aworkable spatial systemfor human beings. The information has to be verysimple It also has to be veryfast 11. 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 transparentfor our minds eye,or We had to be able to mentally liftourselves high enough to see theshelter behind the hill 12. But there is more... LX/2002 We have to recognize it without delay and fail; That rules out the top vertical view. Today its hard to imagine that a map can look any other way 13. Situation: LX/2002 14. Situation: LX/2002 The correct direction to properly oriented objects seen from the side But...direction is from here to there If thehereis unknown, the direction cannot be know! Direction Monitoring System (Inner compass) 15. Spatial system LX/2002 We know where we want to go, and how the shelter looks. Now we need to know where we are. (Lux: EXPO or CCB) Dead Reckoning System (updates location) 16. LX/2002 Direction Frame Inner compass Dead Reckoning System Update location Map ??? 17. LX/2002 Imagine that you are on a city street that you know very well. Then you obviously know where you are. Buthowdo you know that? Cognitive maps 18. 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 labelmap Better would be to call it:Awareness of our familiar environment 19. LX/2002 You recognize thelandmarksaround you. But On your cognitive map you can alsoseearound the corner.Cognitive maps 20. LX/2002 Around the corner: Awareness of our familiar environmentCognitive maps Where does it come from? >>> 21. Cognitive maps LX/2002 We dont 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 >>> 22. Example 1 > Flight update LX/2002 Example 1 > Flight update 23. Example 1 > Flight update LX/2002 Example 1 > Flight update Northon the bottom of the map 24. LX/2002 Example 2 > Map Costa Azul 25. LX/2002 Example 3 > EXPO 98 North must be towards the top of the map. Always. 26. Always? LX/2002 27. We rely on outstanding features like the ocean or mountains. EXPO has the tower and the river. LX/2002 28. 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. 29. 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? 30. 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 31. 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. 32. The Expedition(hiking and holiday) LX/2002 Holiday > Memorabilia > Pictures 33. The Expedition(hiking and holiday) LX/2002 This chemistry is only possible when you actually visited the place. Otherwise you see just the picture... 34. 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 35. LX/2002 Dominant surroundings come from a direction frame during childhood How did a handicap like this survived the evolution? 36. Navigation on the Desktop LX/2002

  • The problems with metaphors
  • Bob software

37. 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

38. Navigation on the Desktop LX/2002

  • The original idea was limited
  • (different windows on monitor)
  • Alan Kays solution was to regard the screen as a desk
  • It wasnt very convincing, but the metaphor was NOT an attempt to simulate real world...

39. Navigation on the Desktop LX/2002

  • The triumph of Microsoft Windowsconfirmed 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)

40. BOB software LX/2002

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

41. Magic Cap LX/2002 42. Bob software LX/2002 43. 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!

44. 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.

45. 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)

46. BOB software LX/2002 Wrong

  • BOBisthe 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)

47. Metaphors(Final thought) LX/2002

  • Is a metaphor always wrong?
  • (If its not the same, how can it help you?)
  • Importance of the difference
  • (Windows versus Windows)
  • Does it help you understanding?
