• OB_Box_right_wood: the smaller part of the TV on the right

• OB_Glas: the screen's glass

• OB_Frame: the grey rubber around the glass
• OB_Button_small: the three grey control dials
• MovieSwitch: a Switch node containing 3 geometries each having a movie-texture from movie1.wmv to movie3.wmv
• TIMER_START_MOVIE01: when this timer gets started the movie-texture MOVIE01 will get the command startTime and start playing, same goes for 02 and 03.
• TIMER_STOP_MOVIE01: when this timer gets started the movie-texture MOVIE01 will get the command stopTime and stop playing, same goes for 02 and 03.

Description of the Workflow:

• Start:
  • Like every other workflow this one starts with "Start Action", "Activate camera" and "Load tracking configuration".
  • The workflow consists of 2 separate VRML-files, which are loaded via "Load geometry". Before you can load a model you have to add it to Resources. After it is known to the system you can simply select it from the dropdown-box.
  • With a "Set VRML field"-action the first movie is set visible by changing the whichChoice-value of the Switch-Node MovieSwitch to 0.
  • Two different action-paths are then automatically triggered:
    • Side-Path:
      • With a "Start timer"-action the timer named "TIMER_START_MOVIE01" is started, then movie1.wmv plays.
      • With a "Set VRML Field"-action the first option of the Switch ChannelNrSwitch gets activated.
      • After 2000 ms (2 seconds) ChannelNrSwitch's whichChoice value gets changed to -1. This means that no child object of the Switch node at all is visible. After these steps the side path ends.
    • Main-Path:
      • The action "React on tracking target rotation" waits until the marker with the specified CosID 2 is rotated up to a certain degree of 30. Depending on the direction of the marker-rotation different actions get triggered:
        • If the marker is rotated counterclockwise:
          • As soon as the timer named "TIMER_STOP_MOVIE01" is started via the action "Start Timer" movie1.wmv is stopped.
          • After half a second (500ms) the action "Set VRML field" switches from 0 to 1, thus making movie1.wmv invisible and movie2.wmv visible.
          • From here the same functions as above are repeated for the other two channels.
        • If the marker is rotated clockwise:
          • Movie1.wmv also get stopped but after 500 ms movie3.wmv is displayed instead of movie2.wmv.
          • From here the same functions as above are repeated for the other two channels.
