BLANDCorporatio thank you very much!!! I have to think about what we've discussed..and if I have any other problem I'll post. Thank you! Best regards

Yes, you got it perfectly..:) I understand the difference between the orientation relative to a link and to room. I have to find out the degrees of freedom. So if I understood there are combinations of links that I can describe them with one number (like elbow joint), but there are also some...

Well let’s say that I’ve recorded a hand wave with all sensors. I’ll have data for all links. So in classification I want to have firstly hand, then arm, etc. These links that best describe each gesture that is being recorded. So I want one value for each link, not the 3 euler rotations..

Thanks for the first! For the second: it's a bit expected the criterion, and we know the results but it depends on the gesture that the user will make and I consider that this will help me in the gesture recognition. So being more specifically, I want to classify the links that best describe...

Sorry for the terminology.. Is there any reference describing these relations between the links and the degree-of-freedom, which I could find? In the long term I want these rotations for gesture recognition. But in short term I want to make some statistical analysis, a classification of the...

Well, we have a suit with inertial sensors that capture/record the upper human body. We have sensors for each joint (hands, arms, shoulders, neck, etc). Also for each joint we record per frame 3 euler angles in degrees. If I understood correctly from the theory, euler rotation is a rotation...

First of all thank you very much BLANDCorporatio! Secondly I think that it's clear what you've proposed to me. Also for your last question and if I understood correctly, the system doesn't have only one rotational degree of freedom, because each joint has 3 Euler rotations, referring to the 3...

SPSS is a program for statistical analysis. By saying Gimbal Lock I meant this Gimbal lock - Wikipedia, the free encyclopedia . And that I cannot just select one axis of rotations for all joints, as all three are interdependent. Well I have recording with sensors someone doing some gestures...

Hi, I would like to ask if anyone knows how to convert/combine x,y,z euler angles into ONE value? Is there any function for this? I've searched but I found the conversion into matrices or quaternions, but these output more than one value (i.e. rotations and vector). Am I correct? I'm trying to...
