Vangelis has been tracking the ready-to-wear IMU space more carefully than I.
I am hoping IMU's are a temporary bootstrap and that we will have less encumbering techniques with
absolute position measurements such as the upcoming Sixense Stem system.
My fear is that we will be surrounded by even cheaper, slower, uncalibratable IMU's before the situation
improves substantially.
Keep an eye out for the next-gen x-OSC with a built-in charger and better IMU.

Can’t recall the make.

I would add that the observation/performance pair problems are connected to the problems of signal/noise - both dependent
on POV and preschema. Another tactic I have started to explore is the material agency of "lenses" (or filters as lenses are framed in the signal processing literature). This points to bringing in the material aspects of intersubjectivity - one of the key conundrums of quantum theory that has had to invoke a lot of magic around the macroscopic and microscopic properties
of "apparatus" to keep the rest of the theory coherent.
