  15. Focus of This Presentation User Interface Design • Project Overview • User Interface Design • Command Line Interface • Graphical User Interface • Architecture • Software Demo Schroeder Bernstein

  16. Command Line Interface User Interface Design • Maximum Event • Event Specification File • Standard X Arguments • Generator Command % geek-m 1000 -l labels -display yquem:0.0 -- facmon -t3 -l -z Schroeder Bernstein

  17. The GEEK Window User Interface Design Schroeder Bernstein

  18. Current View User Interface Design • Horizontal Histogram • Scale • Event Labels • Scroll Bar Schroeder Bernstein

  19. Global View User Interface Design • Event Space Visualization • Current View Location Schroeder Bernstein

  20. Status Bar: Collection User Interface Design • Counting • Events Counted When Received • Not Counting • Events Ignored When Received Schroeder Bernstein

  21. Status Bar: Update User Interface Design • Automatic • Update at Periodic Intervals • Manual • Update on Explicit User Request Schroeder Bernstein

  22. Status Bar: Sort User Interface Design • By Event • Ordered by Increasing Event ID • By Count • Ordered by Decreasing Event Count • By Nothing • Order Unchanged Schroeder Bernstein

  23. Status Bar: Elapsed Time User Interface Design • Time During Which Counting Occurred • Displayed As … • Hours • Minutes • Seconds Schroeder Bernstein

  24. Button Bar User Interface Design • Start • Count Events When Received • Stop • Ignore Events When Received • Reset • Set Counts to Zero • Update • Immediately Update Histogram Schroeder Bernstein

  25. Menu Bar: File User Interface Design • Save • Save Event Counts • Save As … • Save Event Counts in Named File • Preferences … • Modify User Preferences • Exit … • Terminate GEEK Session Schroeder Bernstein

  26. Menu Bar: Screen User Interface Design • Sort • By Event Set Criteria “By Event” • By Count Set Criteria “By Count” • By Nothing Set Criteria “By Nothing” • Update • Automatic Set Periodic Update • Manual Set Update on User Request Schroeder Bernstein
