Hello All,
I am currently a part of a project that is looking to calculating the angle of the head during two different movement patterns. During the first one, the individual is looking straight ahead at a monitor, roughly at eye level, while the second movement is multi-axial. For the multi-axial movement, there are four monitors set up like a square, where the bottom two are closer to the ground and the top two are closer to the ceiling. The head movement is from the lower right monitor to the top left monitor. The global coordinate system of the lab is X= ML, Y= AP, Z= vertical. To calculate the angle of the head in space for the straight ahead monitor, I imagine an XYZ rotation sequence would suffice, but for the multi-axial movement, I think this rotation would be inappropriate (I'm thinking a ZYX rotation would be more suitable). I have looked for standard rotation sequences, but have not been able to come across any, does any one have any suggestions as to how we should go about tackling this problem. Thank your for the help in advance.
