Automotive and aircraft interior designers have common concern with the proportion of user population accommodated with safety and full capability. Traditional design methods are shown to result in inadequate population accommodation for cockpit designs. An alternative method, Computerized Accommodated Percentage Evaluation (CAPE), is reviewed and cockpit CAPE models are described. This overview is used as a framework for consideration of potential for CAPE automotive models. It is concluded that a CAPE model for automotive vehicle interiors can be readily developed; and the Edwards et al Cockpit Assessment of Reach (CAR) model should be considered for the base of such a model.
