DESCRIPTION:Predictive Interaction using the Delphian Desktop\n\nAvailable
  at:\nhttp://doi.acm.org/10.1145/1095034.1095058\n\nAbstract:\n\n"This pap
 er details the design and evaluation of the Delphian Desktop\, a mechanism
  for online spatial prediction of cursor movements in a Windows-Icons-Menu
 s-Pointers (WIMP) environment. Interaction with WIMP-based interfaces ofte
 n becomes a spatially challenging task when the physical interaction media
 tors are the common mouse and a high resolution\, physically large display
  screen. These spatial challenges are especially evident in overly crowded
  Windows desktops. The Delphian Desktop integrates simple yet effective pr
 edictive spatial tracking and selection paradigms into ordinary WIMP envir
 onments in order to simplify and ease pointing tasks. Predictions are calc
 ulated by tracking cursor movements and estimating spatial intentions usin
 g a computationally inexpensive online algorithm based on estimating the m
 ovement direction and peak velocity.\nIn testing the Delphian Desktop effe
 ctively shortened\npointing time to faraway icons\, and reduced the overal
 l physical distance the mouse (and user hand) had to mechanically traverse
