Total newbie here, hoping for some guidance on a novel(?) use of motion. I do behavioral neuroscience research with earthworms, and want to use Motion to monitor the movement and position of an individual worm on a surface of about 15x15 inches. I think that I can set the motion detection threshold low enough that I can detect the slow movement of the worm if images are not taken too frequently (something like a setting around 10 with images acquired every half second - still playing with the parameters). Environment is controlled and lighting is constant, so I can work with a real low threshold like this.
Here's my question for now. Documentation indicates that "Motion can execute external commands based on the motion detection and related events." However, I can't find information concerning the nature of the command. Is it a C statment? Can the command do something as eleborate as control the signal sent to the computer's parallel port? If so I could exert the kind of experimental control that I need (e.g., worm moves far enough, turn off a light or turn on a vibratory stimulus).
See an earthworm in a running wheel at my web page: http://campus.albion.edu/wjwilson/research/
Apologies if this is an easy question and I just overlooked the obvious answer somewhere. Thanks for any guidance,
