Geoff’s voice avatar has some trouble wrapping his head around the sensor fusion algorithms in head-tracking devices - in part because as a voice avatar by nature he neither has a head, nor a body. Fortunately, Bosch expert Ye Lu is excellent in explaining how different sensors can help correct each other’s errors and why school mathematics has its limits when you want to accurately determine rotation angles. In this deep dive, we also learn why the inventions of old geniuses like Foucault, Euler and Gauss are still relevant for state-of-the-art VR headsets, earbuds and other wearables.
