  1. 1-D cs5984: Information Visualization Chris North

  2. Today • Eick, “SeeSoft”, p 419 • purvi, prasuna • Eick, “Data Visualization Sliders”, p 251 (2 pages)

  3. Navigation Strategies • Detail Only • Zooming • Overview+Detail • Focus+Context (Distortion, fisheye)

  4. Fisheye Menus • http://www.cs.umd.edu/hcil/fisheyemenu/ • Very Fast • due to mouse mechanics, no clicking, mostly vertical sliding • Alphabet overview helpful • Fisheye context not useful in this case? • Might be more useful in SeeSoft where miniature representation gives important information • Limits # of readable items to ~10 • Wasted space at top- and bottom- right • Distortion problematic? • Alphabet overview distorted at A and Z • Scale limited? • Possible improvement: • Same alphabet overview (without end distortion) • Remove fisheye, maximize readable items like scrolling version • Same fast mouse mechanics, scroll fast on left, no scroll on right

  5. Music Animation Machine • Good for visualizing music during serial playback, relate audio to visual structure • Visualizing entire compositions: increase information density • See patterns of phrases, instruments, etc.
