Odo

Odo is a so-called odometer, a counter of the distance one travels using the mouse-cursor on screen.
Since this kind of data takes some time to collect, users are more interested in when they did how much with the mouse. A keystroke-counter was added and a link to a local database, to be able to look up ones history of activity.
The graph displays the measured values with a combination of colors, at one minute per horizontal pixel:
Upper graph:
· Green: Horzontal mouse movement
· Red: Vertical mouse movement
Lower graph:
· Green: Keystrokes
· Red: Mouseclicks
· Blue: Application switches
Since these are the basic colors, overlapping dispay results in different colors: red and green make yellow, blue and green make light-blue (cyan), blue and red make purple (magenta), and all three make white.
