The Original Fisheye View • George Furnas, 1981 (pg 311) • Large information space • User controlled focus point • How to render items? • Normal View: just pick items nearby • Fisheye View: pick items based on degree of interest • Degree of Interest = function of distance from f and a priori importance • DOI(x) = -dist(x,f) + imp(x) f x

  6. Example: Tree structure • Distance = # links between f and x • Importance = level of x in tree Distance: I 3 A 2 a 3 i 4 ii 4 b 1 i 2 ii 0 B 4 a 5 i 6 ii 6 b 5 i 6 ii 6 Importance: I 0 A -1 a -2 i -3 ii -3 b -2 i -3 ii -3 B -1 a -2 i -3 ii -3 b -2 i -3 ii -3 DOI: I -3 A -3 a -5 i -7 ii -7 b -3 i -5 ii -3 B -5 a -7 i -9 ii -9 b -7 i -9 ii -9 f
