Level of Detail (LOD) techniques for real-time rendering and related perceptual issues have received
a lot of attention in recent years. Researchers have also begun to look at the issue of
perceptually adaptive techniques for plausible physical simulations. In this paper, we are particularly
interested in the problem of realistic collision simulation in scenes where large numbers
of objects are colliding and processing must occur in real-time. An interruptible and therefore
degradable collision handling mechanism is used and the perceptual impact of this degradation is
explored. We look for ways in which we can optimise the realism of such simulations and describe
a series of psychophysical experiments that investigated different factors affecting collision perception,
including eccentricity, separation, distractors, causality and accuracy of physical response.
Finally, strategies for incorporating these factors into a perceptually adaptive real-time simulation
of large numbers of visually similar objects are presented.
