Hello Everybody,
Currently I am working on
my diploma thesis, which is to provide an auxiliary
vector for a WLAN based RTLS (Real-time locating system).
Because it has flaws in it, that come from losing IP packets,
I have to construct an auxiliary system to it based on
I am wondering if you could help me a bit.
I use GlovePIE to acquire the accelerometer data.

We presume that the device is fixed in one of the 3 axis.
So that we would like to use it like an indoor locating system
on room level, we only need the two dimensions(forward/backward,
My question is do you know a method of getting the brief trajectory
of the wiimote in 2D.
I know about a response to this on the link below:
But could you advise me how to process those acceleration data
(?some transformation or filtering?)
to get an auxiliary vector, it does not have to be very precise.
Besides I am using the RelAcc parameters to determine the velocity,
but it does not provide correct information. Because of this if I
want to calculate position, I integrate again and it shows me totally
wrong data.
Could You please tell me if I wanted to get raw data from the Wii Remote
using C++ where should I start finding.

I am not exactly sure I get your question (I have been up for a good 30 hours :( ) but what kind of raw data are you for? If it is something like just three dimensional accelerations then I am sure I can hook you up with the code.
Just let me know.
