14. Homework 2 results “Show me the data!!!” Browse, not search
Start by showing ALL data, instead of NO data
Paths + times
Browse, not search
Exploratory, not algorithmic
System canNOT optimize a path for me, I can.
E.g what if x, y, or t in my questions are not known?
Free your mind
No more standard GUI (Forms, buttons, combo-boxes, etc)
Graphics + direct manipulation
Think Different.
Set your sights big
When you think you are done, show more

15. Homework 2 solutions 3D: Color: Schedules: Map  x,y; Time  z
Paths = 3d curves; buses = points
Rotation, slicing
Color:
Map  x,y; Time  color
Paths = 2d colored curves; buses = points
Timeline
Schedules:
Locations  x (parallel-coord lines)
Time  y
Paths = connected line segments across par-coords
