I would like to build a device as seen on the picuture.
My question concerns the movement of the device, since it will be carried around by people. I can set a fixed time interval and try to move with the right speed, but I would like to have this idiot proof.
What about one of those sensors from the cheap mocap suits? I don't know what they are called and couldn't find them online. Basically you reset their position, and after that they give you XYZ acceleration. But it think this is not a normal gyro?

A gyro provides you rotational speed information while an accelerometer provides the accelerations. Theoretically you need positional information. The accelerometer can help you by providing some approximations but with the cheap devices you mentioned you'll never get exact values. For the task you're trying to achieve it should be sufficient.
I'm not sure a consumer IMU will be good enough for this. But it would be great to try it.
The example photo shows the steps of the person carrying it. You probably don't want the IMU to filter all of that out. Finding the right balance will take a lot of testing.
