IMU based motion capturing
hello,
this first post , i'm new whole arduino thing.
what want this:

the closest diy-project found far this:

http://www.jpattillo.net/?page_id=72 corresponding website.
at beginning want focus on motion capturing, not feedback mechanism.
my idea realizing affordable motion capturing system looks this:

in example use 3 imu or 2 imu in future use @ least 7 cover whole body.
this why think using i2c multiplexer avoid i2c adress issues.
i haven't thought coding, first want know wether possible side of hardware.
what think?

is possible? of course. easy? don't know.
my first concern how information needs passed , forth between imu , arduino. can data 7 imus fast need it?
if using pre-fabbed library, freeimu, can handle i2c mux? if not you'll have modify or write code. not impossible, maybe not trivial either.
how processing time needed crunch sensor data? processing 7 imus worth of data 100 times per second might arduino. how fast need update / log positions? golf swing, you'd want update pretty fast, other applications might not need fast updating.
how data needs sent out arduino pc or other device? serial link typically runs @ 9600 baud, pretty limiting. can run serial link faster, use ethernet or wifi, it's gonna take time , processing power data out wherever needs go. don't think limiting factor, worth thinking about.
in summary, don't think hardware prevent doing want, unless need fast updating. may end needing more 1 arduino when 7 imus, can started 1 , build go.
