“…Future work could be used to establish guidelines for project managers to better structure and prepare design reviews with the right individuals and right tools. Studies have explored the potential of virtual reality environments in design review activities, an intriguing idea for information sharing and evaluation (Aromaa et al, 2012, Freeman et al, 2016, Casenave and Lugo 2018. Future work could also be used to inform CAD system designers to create tools better suited for stages prior to and beyond the detailed design phase, or create workflows that are more friendly to non-native CAD users.…”

In this paper, we present the results of a survey of new product development practitioners regarding their design review experiences. We surveyed 128 product development professionals on their experience and preferences in design reviews. We found that the goals and type (location / synchronicity) of design reviews change over the course of a product development project. We found that the majority of design review meetings continue to be held as co-located, live, in-person meetings. For reviewing 3D models, we found that a native CAD package (rather than a viewer, or fixed views, or a physical prototype) is the most commonly used tool. We found a difference between Designers (more likely to be product engineers) and Non-Designers and their access to CAD software, as well as their preference for which tool to use at the design review for 3D model evaluation. We hope that our findings spark future work related to better understanding design reviews and design reviewers in context. Design reviews are an important part of industrial product development processes, so we believe future studies have a large potential to improve these design activities

“…The empirical part of the presented research has been conducted as a quantitative and comparative experimental study that employs a descriptive and inferential statistical testing. The design of the study is based on principles and methods described by Robinson [41] and guided by published experimental studies concerned with spatial perception as one aspect of a design understanding in engineering domain (for instance, [6], [24], [34], [42], [43]). In addition, studies from the domain of psychology were used as a basis for a definition of tasks and spatial perception measures (some examples are [20], [40]).…”

Spatial Perception of 3D CAD Model Dimensions and Affordances in Virtual Environments

et al. 2020

Design understanding and needed level of the accompanying spatial skills that enable it depend on information input provided by a visual representation of a design solution. During product development, designers use models to visually represent a design solution. These visual representations can be mediated by various technologies (for example, an immersive virtual reality (IVR) technology or 2D user interfaces such as a monitor display), providing designers with different types of information. Capabilities of an IVR technology such as stereopsis, eye-height reference, spatial updating, and multimodal interaction, have shown a potential to mitigate the cognitive load and the need for highly developed spatial skills enabling design understanding. Nevertheless, specific design understanding aspects for which IVR technology may be beneficial over conventional 2D user interfaces are yet to be clarified. The conducted experiment aimed to explore differences in designers' spatial perception of spatial properties and relations (affordances) of a design solution in virtual environments (VEs). The design solution was presented by a 3D CAD model in immersive virtual environment (IVE) and non-immersive virtual environment (nIVE). IVE was mediated using the IVR technology (head-mounted display; HMD), while nIVE using the conventional 2D user interface (a monitor display, a mouse, and a keyboard). Results indicate that engineering students more accurately perceive spatial properties in the IVE than nIVE. Besides, it is suggested that the likelihood of making the correct judgment of the affordance is similar in both VEs.

“…A subset of prior work involves the interaction of subjects with a CAD model in a Cave Automated Virtual Environment (CAVE) [41,42]. CAVEs are used to create a virtual room around the subject, where they interact with a virtual product and real-world objects in the room [42,43], as well as study groups of participants at once in a virtual environment [44].…”

Development of Low-Fidelity Virtual Replicas of Products for Usability Testing

et al. 2022

Designers perform early-stage formative usability tests with low-fidelity prototypes to improve the design of new products. This low-tech prototype style reduces the manufacturing resources but limits the functions that can be assessed. Recent advances in technology enable designers to create low-fidelity 3D models for users to engage in a virtual environment. Three-dimensional models communicate design concepts and are not often used in formative usability testing. The proposed method discusses how to create a virtual replica of a product by assessing key human interaction steps and addresses the limitations of translating those steps into a virtual environment. In addition, the paper will provide a framework to evaluate the usability of a product in a virtual setting, with a specific emphasis on low-resource online testing in the user population. A study was performed to pilot the subject’s experience with the proposed approach and determine how the virtual online simulation impacted the performance. The study outcomes demonstrated that subjects were able to successfully interact with the virtual replica and found the simulation realistic. This method can be followed to perform formative usability tests earlier and incorporate subject feedback into future iterations of their design, which can improve safety and product efficacy.
