Proprioceptive diversity 1 min

Ageing, stroke and conditions that affect sensory or motor function can all distort our sense of limb position. Personalisation can help keep interactions comfortable. For example, allow users to adjust motion-gain (the ratio between their real movement and the avatar's) and provide clear, high-contrast outlines of virtual limbs so visual cues can compensate for reduced proprioceptive and motor acuity (see the section on Plasticity).

Sensory mismatch 1 min

Sensory mismatch can induce nausea, dizziness and lingering disorientation. Adaptation periods can help. Provide content warnings, preview videos, opt-out points, clear exit routines and seated decompression recovery zones⁷⁷.

In virtual production, actors can fall over with background shifts. Bill Burr (the actor who played Migs Mayfield in the Mandalorian) said: "If the camera moves behind me, the stuff behind you moves, you get like, vertigo. So that's why I think the acting in those scenes is really good - you have to lock in on the actor because if you start looking at the other stuff you're gonna tip over"¹³⁵.
