> speed and acceleration also varies Also tilt and pressure. But I didn't notice rotation in the sections I skimmed. With XR coming to unshackle visual output from fixed flat small screens, the question arises: how might we unshackle input? Say one can type while holding a single chopstick. What might one do with 7DOF fingers and brush in 2D and 3D? If a laptop keyboard was also a touch surface, and the space above it were tracked? What does an IDE look like for typing and painting code, where the "paint" is alive? So I'm interested in stylus and brush movement vocabularies, and gesture recognition.
