An interesting question. In this context, I would guess only saccades and VOR would be significant enough to bother simulating. VOR is easy; for saccades you need to know their stochastic properties with regard to timing and size. Unfortunately this has not been explored very thoroughly, but I've played about with a simulation using some of the information in the accounts below and the effect can be uncannily life-like.
