Jumping and Noise in head tracking

[cyclonseye]

Hello

My name is Hyeob Choi, and I am using Vizard and EVarT for head tracking

and making vision correspond to head track information.


I made a body in EVarT, and Vizard reads the body's information(6 DOF).

Then, I linked view point and the body, and I could make head tracking vision.


However, there is a problem.

The vision periodically jump.

It is unrelated to EVarT. It also jumps when EVarT is not turned on.

Why does it happen?


Another question is about noise.

There is some noise in EVarT information.

I want to ignore it, although head tracking sensibility decreases.

How can I do it?


I would really appreciate your help.

Thanks.
