Assignment
• Read for Thurs• Wise, “Themescapes”, book pg 442
» maulik, chris r
• Read for Tues• Hearst, “Tilebars”, web
» umer, ashwini
• Homework #3: due Thurs
• Mid-Project status report: due Tues
Homework 2 results• “Show me the data!!!”
• 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
Homework 2 solutions• 3D:
• 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
Visualizing travel plan schedules
• Timing of :
• potential Airline flights, layovers, stops
• driving
• Events, meetings
• Timezone changes
• Multiple stops
• Group travel! From different locations…
• Cost
