“…However, there are several everyday situations, e.g. car egress, which are performed unilaterally by all subjects in early adulthood and even most of the subjects in late adulthood [36]. As motor tests require rigorous objectivity, ADL movements like car egress [36] with its many degrees of freedom are not as suitable as the unilateral STS movement, which can be controlled more easily.…”

Background and Objectives:Sit-to-Stand (STS) movements are fundamental activities of daily living. As STS movements can be physically demanding especially for the elderly, bi-and unilateral STS movements are frequently used in motor tests to measure lower limb strength. In contrast to bilateral STS movements, the knee joint loads occurring during unilateral STS movements as well as the influences of chair height or lower limb dominance are still unknown. Methods:In a randomized study approach knee joint loads during unilateral STS movements from three different chair heights have been analyzed using biomechanical motion analysis in a population of 19 healthy middle-aged adults. Additionally, the influence of lower limb dominance and the level of perceived exertion have been investigated. Results:Lower limb dominance had no effect on knee joint load. In contrast, chair height significantly affected the peak shear forces in anterior (high: 3.94 ± 0.63 N/kg; low: 4.09 ± 0.61 N/kg) and lateral (high: 1.52 ± 0.79 N/kg; low: 1.78 ± 0.88 N/kg) direction as well as the peak knee adduction moment (high: 0.56 ± 0.29 Nm/kg; low: 0.65 ± 0.32 Nm/kg). Additionally, chair height but not limb dominance significantly affected the level of perceived exertion (high: 11.1 ± 2.8; low: 12.5 ± 3.5). Conclusion:The detected knee joint loads occurring during a unilateral STS movements are similar to those of other activities of daily living like e.g. stair ascent and thus, unilateral STS movements are applicable for usage in motor tests for middle-aged subjects. While lower limb dominance has no impact on the knee joint load, lower chair heights increase the load on the knee joint. Therefore, chair height should be considered when using unilateral STS movements in motor tests.

“…Ce sont les outils les plus simples à utiliser pour mesurer avec précision des postures et des mouvements [32]. En couplant ces instruments de mesure à un logiciel d'analyse de l'activité (ici Kronos-CAPTIV®) il a été possible de mesurer les angles des articulations du bas du dos, des genoux et de la nuque, articulations reconnues comme étant impliquées dans le mouvement d'entrée-sortie de véhicule étudié ici [12,8].…”

The automotive industry is so competitive that new vehicles must quickly be proposed. Toward this ends, conception processes enhancing an early involvement of several professions were developed. Ergonomics is one of these professions and its early considerations, when designing a vehicle, can mostly be based on numerical intermediaries' objects of the vehicle and the future user. Even though the use of numerical tools is widespread, physical prototypes are still required in the automotive industry in order to validate ergonomics aspects of the vehicle. However, these prototypes are expansive, complex to implement and only take part in a late stage of conception. In this context, the current article presents the potential contribution of a multi-scale mockup that could be used in order to early take into account ergonomics aspects when designing a technical vehicle. The originality of this mock-up lies in the fact that it is scalable and easy to implement. Doing so, it can thus, contrary to traditional physical mock-ups, be used early during the conception process.

“…Digital vehicle models and digital human models are used to assess the ergonomics of vehicles during the early phases of design, providing simulation of the physical interactions between target customers and the vehicle (Chateauroux & Wang, 2010). Digital Human Modelling (DHM) uses digital manikins that can be changed in size and shape to represent the target range of users.…”

“…There has however been a recent focus on research into DHM for entry and exit (e.g. Chateauroux & Wang, 2010;Cherednichenko et al, 2006;Kawachi et al, 2005;Monnier et al, 2006;Reed & Huang, 2008). With DHM the manikin can be moved as a real person moves, but cannot reliably register discomfort or satisfaction.…”

AbstractEase of entry and exit is important for creating a positive first impression of a car and to increase customer satisfaction. Several methods are used within vehicle development to optimise ease of entry and exit, including CAD reviews, benchmarking and buck trials.However, there is an industry trend towards digital methods to reduce the costs and time associated with developing physical prototypes. This paper reports on a study of entry strategy in three properties (buck, car, CAVE) in which inconsistencies were demonstrated by people entering a vehicle representation in the CAVE. In a second study industry practitioners rated the CAVE as worse than physical methods for identifying entry and exit issues, and having lower perceived validity and reliability. However, the resource issues associated with building bucks were recognised. Recommendations are made for developing the CAVE and for combinations of methods for use at different stages of a vehicle's development. Keywords: entry exit, automotive Highlights: Inconsistent entry strategies were observed in a CAVE virtual environment  The CAVE needs development to support design for ease of entry and exit  Representation of vehicular hard points is necessary for optimising entry and exit  Various combinations of methods are required at different stages of vehicle development 2
