Abstract

This proof-of-concept pilot study explored virtual simulation methodology to quantify blind-spot line-of-sight using avatars derived from an older driver database (n = 100). Siemens Jack software simulated the blind spots of eight older driver avatars (four female). The male and female avatars were scaled to be small (25th percentile) and large (75th percentile) based on the height distribution for the older driver database, and had either “normal” (65 degrees) or “abnormal” (50 degrees) neck range of motion (ROM). A virtual model of a Volkswagen Beetle was used to illustrate left and right blind-spot line-of-sight for each avatar. Average line-of-sight between blind spots was 22.3 per cent and 10.4 per cent in the “normal” and “abnormal” rotational neck ROM conditions, respectively. Older drivers with functional impairments affecting neck ROM are more likely to have problems with left blind-spot line-of-sight. Findings are discussed with regard to vehicle design considerations for older adults.

Résumé

Cette étude de preuve de concept pilote a exploré une méthodologie utilisant la simulation virtuelle pour quantifier les angles non visibles des visibilités optiques, et en utilisant des avatars tirés d’une ancienne base de données (n = 100). Les logiciels Siemens Jack ont simulé les angles morts de huit avatars des conducteurs âgés (quatre femmes). Les avatars masculins et féminins ont été mis à l’échelle aux petites tailles (25e centile) et aux grandes tailles (75e centile), basé sur la distribution de la hauteur de la base de données des conducteurs âgés, et ils avaient l’amplitude de mouvement du cou “normal” (65 degrés) ou “anormal” 50 degrés (ROM). Un modèle virtuel d’une Volkswagen Beetle a été utilisé pour illustrer les angles morts lignes de visée à gauche et à droit pour chaque avatar. La moyenne ligne de visée entre les angles morts était de 22,3 pourcent et 10,4 pourcent dans les conditions «normales» et «anormales» de rotation du cou (ROM), respectivement. Les conducteurs âgés ayant des troubles fonctionnels affectant le cou (ROM) sont plus susceptibles d’avoir des problèmes avec l’angle mort / ligne de visée gauche. Les résultats sont discutés comme ils se rapportent à des considerations du dessein des véhicules pour les personnes agées.
