Dynamic Visual acuity, eye movements and peripheral acuity for moving targets.
Dynamic visual acuity was included as the last component in the final model.
However, when acuity relates to moving targets ir is referred to as Dynamic Visual Acuity (DVA) in order to distinguish it from acuity measures with stationary targets (SVA).
The ability of an observer to resolve moving targets - so-called dynamic visual acuity - has been found to be one of the few visual measures that predicts driving performance (see Sheedy & Bailey, 1993).
