    Hi Greg:

    Andrew Milne, a research engineer who formerly worked with me and
    with Jim Johnson at Western, has had a lot of experience with the
    Flock and LabVIEW. I'm going to copy this message to him (he's in Med
    School here at Dal currently) and I'm sure he'll be happy to chat
    with you about it. He has some routines which have been used in both
    labs for orthopaedic and, well, nose-scanning applications.

    It is a complete pain, but we managed to do it. I started
    with a Labview driver that is available commercially and
    tinkered my way to what I needed. The big secret I
    found was to be very aware of the handshaking protocol
    for the serial port. We ended up making a serial cable
    with all of the handshaking lines cut (based on the wiring
    in the manual). The other trick is to manage to stamp time
    on the signal so you can match it up with A/D board data.
    The driver we purchased was good for that and may be
    worth avoiding the headache of doing it yourself (unless
    you have a good Labview programmer on staff).

    Dear Greg,
    This is just to let you know that I am also interested in responds to
    your question.
    At the moment we use the FoB proprietary DOS program and convert it
    to MatLab for further processing. This works rather clumsy, but it
    If you are interested in these things, let me know.

    I have developed a LabView vi for the MotionStar, which is why I asked. I
    know others have written it for the RS232. It really isn't hard to do.
    The user manual gives all the information you need to construct the string
    you send as a command. And the resulting data format is also
    straight-forward. This is the sort of thing a summer engineering student
    could do for you.

    There are also consultants who will write these VIs for you, but I have
    heard variable reports of the quality of their work. Although I suspect
    that some of the "problems" people have encountered with the consultants
    were really a reflection of poor specifications up front, you should
    of any responses to your e-mail from consultants offering to write a VI
    you. Check the person's previous customers.



    I got this note that you sent to Glenn and Allison forwarded to me. I
    with both of them at Ford, and am currently in the middle of setting up a
    Human Simulation lab using Flock of Birds. I would be more than happy to
    answer any questions you have the technology, as best I can. Some general
    information is that the sensors used with Flock of Birds are driven using
    magnetic fields to transmit signals to the main receiver. Therefore the
    biggest concern is for interference from any metal in the area. I believe
    that if you can keep metal out of an eight to ten foot radius of where you
    will be working with the Flock of Birds you should be able to avoid any
    distortion. Besides keeping hardware-type equipment (i.e. computers,
    chairs) you also need to be aware of any metal studding in the walls or
    metal in the floor.

    The real-time capture of data is very good if you can avoid the metal
    interference. I have used it in the past in conjunction with Transom Jack
    software, a digital human simulation software developed originally here in
    the States. The movies we have captured were accurate and captured actual
    human motion much better than a person at a desk running a simulation. I
    hope that this is the type of information you were looking for...please
    free to contact me with any more specific questions you may have either
    or in the future.

    Hi Greg!
    Sorry it has taken me awhile to get back to you. I was out of the
    I'm attaching zipped copies of some labview subvi's (saved in version 5.1)
    and a readme file. These are just subvi's we use to test to see if we are
    getting data. (You should be able to specify angle or position). The
    program might not work if you don't have the same hardware at the same
    addresses as we do. If you want to try and use them, give me a call and we
    can discuss some changes if you are having problems.

    I will be out again the rest of this week, but should be in by next Monday
    (19th) and then hopefully no more trips for awhile.

    Good Luck and I hope this helps!
    JoAnne Riess
