Title: Visually aging scroll bar
Inventor: BATES CARY L
IPC: G06F3/0485
Filed: 1992-06-17
Abstract: VISUALLY AGING SCROLL BAR            Abstract of the Disclosure A  visually  aging  scroll  bar  is  associated  with  a window  or  viewport  on  a  computer  display  as  part  of a  computer  system,  and  contains  a  slider  to  indicate relative  positioning  in  the  window  of  a  document, such  as  a  data  file,  image  file,  audio  file,  text file,   or  spreadsheet.    The  current  position  of  the scroll   bar   slider   is   monitored   by   the   computer system.   After  a  first  predetermined  sampling  period has   elapsed,   a   first   region  matching  the   current position  of  the  scroll  bar  slider  is  created.   The visual  appearance  of  the  region  is  determined  by  a predetermined   region  heating  rate.    For  example,   a newly  created  region  starts  at  "cold",  which  can  be indicated  by  a  violet-indigo  color.   After  a  second sampling   period   has   elapsed,   the   computer   system again  checks  the current  position  of  the  scroll  bar slider.    If  the  current  position  still  matches  the first   region,   the  visual   appearance   of   the   first region  symbolically  "warms  Up" as  indicated  by  the region   heating   rate.    This   incrementally   changing visual   appearance   (for   example,    from   violet   to indigo,   blue,   green,   yellow,   orange   and  finally  a deep   red)   continues   for   as   long   as   the   current slider  position  matches  the  first  region,  up  until  a maximum region symbolic "temperature" is reached.
