Virtual and augmented reality allows the utilization of natural user interfaces, such as realistic finger interaction, even for purposes that were previously dominated by the WIMP paradigm. This new form of interaction is particularly suitable for applications involving manipulation tasks in 3D space, such as CAD assembly modeling. The objective of this paper is to evaluate the suitability of natural interaction for CAD assembly modeling in virtual reality. An advantage of the natural interaction compared to the conventional operation by computer mouse would indicate development potential for user interfaces of current CAD applications. Our approach bases on two main elements. Firstly, a novel natural user interface for realistic finger interaction enables the user to interact with virtual objects similar to physical ones. Secondly, an algorithm automatically detects constraints between CAD components based solely on their geometry and spatial location. In order to prove the usability of the natural CAD assembly modeling approach in comparison with the assembly procedure in current WIMP operated CAD software, we present a comparative user study. Results show that the VR method including natural finger interaction significantly outperforms the desktop-based CAD application in terms of efficiency and ease of use.

“…The e↵ectiveness of the tool primarily depends on these parameters. Multimodal-immersive VR systems have shown to produce a good satisfaction for users during modelling and assembly processes [49]. Hence, we are specifically interested in presence parameter -'ability to control', provided by the tools for designing concepts.…”

While Mixed Prototyping has proved to be e↵ective for the assessment of prototypes, this research aims to explore the use of Mixed Prototyping for the generation of early prototypes. To satisfy end-user's needs, new products need to be designed with an early integration of end-user requirements. An e cient way to achieve this is to directly integrate the end-users in the design process and give them an intelligible and interactive tool to perform specific design tasks. Current interactive tools to integrate end-users in the design process provide either a high level of immersion (e.g. CAVE) or a high level of control over the virtual prototype (e.g. Configurators). We designed a new Mixed Reality design tool which simultaneously allows end-users to be immersed in a virtual environment (immersion) and to interact with a virtual prototype and to modify it (control), resulting in e↵ective end user-interactions. In two design use-case scenarios, we assessed the enduser experience and satisfaction while using the tool and we also evaluated the impact of the tool on the creative process and the design outcomes. The findings show that, when users are provided with a tool that allows to directly perform design tasks and modify a virtual prototype, as compared to when they have no control, they are more engaged in the design tasks, more satisfied with the design process and they produce more creative outcomes.

“…The VRSolid system consists of five modalities, including two for output (haptic feedback and 3D visual) and three for input (gesture, speech, and motion tracking). Following this, Bourdot [72] and Toma [35] constructed some similar multimodal systems for CAD in a VR environment. All applications mentioned above are designed to provide an intuitiveness and natural environment for interaction with CAD models, while creating a common multimodal interface that can be integrated with the existing commercial CAD software, such as SolidWorks, Creo, and Parasolid [35,72,73].…”

“…To evaluate the performance and usability of natural interfaces for CAD, we need to establish whether the interface is able to carry out tasks effectively and efficiently and if it is also easy to understand and use for novices in the field of CAD [35]. Generally, each novel interaction system needs to pass several assessment and modification cycles during its development so as to reach a high quality and ensure user satisfaction [115].…”

“…A natural HCI circumvents the limitations of traditional interfaces in terms of interaction space and dimensions, and provides a new end-to-end channel for direct interaction between users and 3D models. By capturing and recognizing the users' EEG, gestures, speech, and other original signals in 3D modeling, natural HCIs can provide a more familiar and direct interaction for users, meaning that the interaction between the user and model can be performed more intuitively and naturally [35].…”

Computer-aided design (CAD) systems have advanced to become a critical tool in product design. Nevertheless, they still primarily rely on the traditional mouse and keyboard interface. This limits the naturalness and intuitiveness of the 3D modeling process. Recently, a multimodal human–computer interface (HCI) has been proposed as the next-generation interaction paradigm. Widening the use of a multimodal HCI provides new opportunities for realizing natural interactions in 3D modeling. In this study, we conducted a literature review of a multimodal HCI for CAD to summarize the state-of-the-art research and establish a solid foundation for future research. We explore and categorize the requirements for natural HCIs and discuss paradigms for their implementation in CAD. Following this, factors to evaluate the system performance and user experience of a natural HCI are summarized and analyzed. We conclude by discussing challenges and key research directions for a natural HCI in product design to inspire future studies.
