  13. 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

  14. 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

  15. 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

  16. Visualizing travel plan schedules • Timing of : • potential Airline flights, layovers, stops • driving • Events, meetings • Timezone changes • Multiple stops • Group travel! From different locations… • Cost
