Detecting in/activity

• Jacob Bandes-Storch Detecting in/activity Nov 15 2008, 23:43
  Hi all,
  
  I'd like to have an app/daemon/something detect when the computer
  becomes active after a period of inactivity, much like iChat does when
  it says "Welcome back! Would you like to change your status from ...".
  Does anyone have any insight as to the best way to do that?
  
  Thanks in advance.

  This mailing list post has code which illustrates how to get the
  current system idle time from IOKit:

  And the bottom of this page outlines how you could then use that
  information to build a timer which will trigger after a set amount of
  idle time has occurred:
