“…Despite the great advantage of using DHMs in the product design process, the DHMs lack a sufficient possibility of modelling user-product interactions to integrate them better in product design processes. Therefore, Wolf et al [9] present a method for interaction modelling based on the concept of affordances. The term affordances was introduces by the psychologist James J. Gibson and describes interaction possibilities provided or afforded by a product or environment towards an actor [10].…”

“…As a consequence, the concept of affordance is not only used in psychology, but has also gained importance in product design [11]. Based on the affordance concept, Wolf et al [9] present a promising approach for modelling user-product interactions with DHM for virtual ergonomics assessments.…”

Using digital human models (DHMs) as the virtual representation of the human body enables the integration of ergonomic assessments in the product design process. Especially the use of DHMs in the early phases of product design can be decisive for competitive factors such as ergonomics or usability. Therefore, we present a method for automatic posture generation for grasping tasks using a musculoskeletal human model. This method enables ergonomic analyses without ergonomic knowledge of the product designer or subject tests. We implemented the presented method for a cylinder grasping scenario using the open source software OpenSim. Subsequently, we evaluated the implementation by means of a parameter study.

“…Affordances may be a key factor towards a useful integration of digital human models into CAD. As proposed in one of our previous contributions (Wolf et al, 2019b), certain geometry elements in a CAD model could for instance be connected to an affordance, using feature technology. The geometry element therefore contains the information on how to interact with it.…”

To successfully facilitate user-centred design, a multitude of different aspects has to be considered, from purely physiological to psychological-emotional factors. The overall aim is to increase the customer satisfaction by enhancing the fit between products and their users in the respective context of use. Further virtualisation of user-centred design processes holds the potential to convey the concepts of frontloading and predictive engineering from classical product engineering. Our vision is to facilitate a comprehensive consideration of user-product interactions in virtual product engineering operationalised by the mission to develop methods and tools to assess and design user-product interactions according to physiological and psychological aspects. A variety of work has already been done to model musculoskeletal user groups, to configure, predict, simulate and optimise physical user-product interactions, to integrate such models into CAD or to map individual subjective values to product design. Nevertheless, there are still research areas to be addressed to enable a comprehensive implementation of the mentioned approach. These are discussed in the present contribution.

“…As it is our vision to establish computer-aided ergonomics in the design process (Wartzack et al 2019;Wolf, Kr€ uger, et al 2019), we conducted a systematic literature review to identify, classify and examine existing proactive interaction models and to understand their scope, limitations, strength and weaknesses. Ultimately, we want to answer the following research questions (RQ): RQ1: Which schematic models describing the userproduct interaction exist and do they use a standardised terminology?…”

Digital human models (DHM) allow for a proactive ergonomic assessment of products by applying different models describing the user-product interaction. In engineering design, DHM tools are currently not established as computer-aided ergonomics tools, since (among other reasons) the interaction models are either cumbersome to use, unstandardised, time-demanding or not trustworthy. To understand the challenges in interaction modelling, we conducted a systematic literature review with the aim of identification, classification and examination of existing interaction models. A schematic user-product interaction model for DHM is proposed, abstracting existing models and unifying the corresponding terminology. Additionally, nine general approaches to proactive interaction modelling were identified by classifying the reviewed interaction models. The approaches are discussed regarding their scope, limitations, strength and weaknesses. Ultimately, the literature review revealed that prevalent interaction models cannot be considered unconditionally suitable for engineering design since none of them offer a satisfactory combination of genuine proactivity and universal validity.Practitioner summary: This contribution presents a systematic literature review conducted to identify, classify and examine existing proactive interaction modelling approaches for digital human models in engineering design. Ultimately, the literature review revealed that prevalent interaction models cannot be considered unconditionally suitable for engineering design since none of them offer a satisfactory combination of genuine proactivity and universal validity.
