“…Another important milestone came in 2009, at the 8th Berlin Workshop Human-Machine-Systems BWMMS'09, whereby a hybrid is created between a mechatronic prototype and a VR image for the purpose of evaluating functional characteristics of a product. The combination of physical and virtual parts was called smart hybrid prototyping (SHP) [25,28,40]. In this experiment, it was possible to interact with a physical product in a virtual environment.…”

“…Thus, the techniques developed in prototyping vary depending on the historical framework where increasing complexity in design processes and efforts to improve decision making leads to the creation of new approaches and techniques to support designers in order to improve product quality. This scenario has given rise to the appearance of hybrid prototypes (HP), defined as the simultaneous presence of a virtual representation, either through virtual reality (VR) or AR and physical support [24,25]. Thus, the application of these processes results in a reduction of time in the manufacture of prototypes and, therefore, of the conceptualization phase [26].…”

The manufacture of prototypes is costly in economic and temporal terms and in order to carry this out it is necessary to accept certain deviations with respect to the final finishes. This article proposes haptic hybrid prototyping, a haptic-visual product prototyping method created to help product design teams evaluate and select semantic information conveyed between product and user through texturing and ribs of a product in early stages of conceptualization. For the evaluation of this tool, an experiment was realized in which the haptic experience was compared during the interaction with final products and through the HHP. As a result, it was observed that the answers of the interviewees coincided in both situations in 81% of the cases. It was concluded that the HHP enables us to know the semantic information transmitted through haptic-visual means between product and user as well as being able to quantify the clarity with which this information is transmitted. Therefore, this new tool makes it possible to reduce the manufacturing lead time of prototypes as well as the conceptualization phase of the product, providing information on the future success of the product in the market and its economic return.

“…Results from Lanzotti et al [2] show that virtual reality offers an interactive possibility to verify human factors requirements. Buchholz et al [3] develop a first initial testbench for human-centered requirements with virtual tools. According to Aromaa and Väänänen [4], the key factors concern modelling of the system (fidelity, virtuality, manipulation possibilities, etc.…”

The involvement of human workers is an essential part of the design of production systems. In this context, test scenarios in Virtual Reality are increasingly used to verify the fulfillment of requirements. This paper proposes a procedure for generating virtual test scenarios. The objective is to support human-centered design by means of virtual measurement systems. The procedure involves three steps: selecting relevant human factors in requirements, modeling the virtual test scenario, and carrying out the verification study. The goal is to advance the significance of testing outputs.

“…Previous studies addressed the concept of driver simulation and its design for nearrealistic UX, giving recommendations when creating a virtual automotive study [7][8][9], i.e., high-fidelity setups and multi-modality for better immersion. Most studies agree on the advantages of VR over conventional testing environments like risk reduction and reproducibility and encourage to use VR for automotive development and early prototyping [7,[9][10][11]. In 2019, Colley et al [12] investigated seven automotive studies in VR using simulation criteria derived from the discussion paper by Winter et al [9].…”

More and more studies in automotive research and development are conducting user-centered development in the emerging field of external humanmachine interfaces (eHMI) in virtual reality (VR). As time, cost and risk are decreasing with progressively affordable sophisticated VR technologies, researchers have shifted to virtual testing. Within this context, they use a variety of methods and technologies to develop new designs but so far little examination has been done towards validity of virtualization and description of the technical setup. As level of immersion is one of the current pillars in VR and technology evolves rapidly, study setups differ a lot in recent years, resulting in poorer comparability. In this paper, our goal is to review the current generation of VR studies in automotive eHMI development and extract in the sense of a lessonslearned approach best practices with regard to their VR setup. For that, we assessed a total of six current studies published between 2017 and April 2020 in automotive eHMI development to extract lessons learned from study designs and virtualization setups. We took a look at hardware and software used as well as study procedure. The results allow us to find useful conclusions on automotive eHMI development practices in VR.
