“…Commercial virtual reality modelling tools such as GravitySketch provide the functionality. Researchers have developed bimanual natural interfaces (Fechter et al, 2020) and proposed a collection of natural interactions for the necessary modelling operations (Harlan et al, 2021). A natural modelling interface could be directly adopted for the hybrid workstation to enable holographic CAD drafting, as shown in Figure 4, right.…”

Many immersive approaches for design activities show a great potential for their specific use cases, but still overall usage of extended reality technology in product developers day-to-day work is little. The user's workflow between classical desktop work environment and its immersive counterpart is interrupted by both a data gap and an interface gap. The three-dimensional product data usually needs preparation and the user has to physically change the interface in use. The hybrid augmented reality computer workstation aims to close these gaps. A hologram of the current model is visualized next to the screen in reach of the user for intuitive inspection and spatial interactions. In this paper we present use cases for this novel immersive workstation in the CAD workflow. An explorative user study of the typical product designer`s workflow reveals the most common activities. Guided by those, eight uses cases are formulated and classified into fundamental, drafting, and modelling CAD tasks. These cases include novel hybrid augmented reality interactions derived from literature, which are assessed with respect to their applicability.

In the product development process, digital support continues to advance. Some work steps during product development are still carried out without assistance. Sketch creation is one of these. Therefore, the content created here is rarely documented due to the effort required for digital transformation. An alternative can be sketching in virtual reality. This article explores whether 3D sketching in VR enables faster sketching and can offer the basic features of hand-drawn sketches. To verify this, a tool for 3D sketching was developed. 27 test subjects were asked to solve one out of two different design tasks using this tool. The experiments were evaluated using video coding to identify the subjects actions. The created solutions have been analyzed about quality. The study showed initial indications that sketching in VR generally enables faster processing while maintaining the same solution quality.

The increased availability of affordable virtual reality hardware in the last years boosted research and development of such systems for many fields of application. While extended reality systems are well established for visualization of product data, immersive authoring tools that can create and modify that data are yet to see widespread productive use. Making use of building blocks, we see the possibility that such tools allow quick expression of spatial concepts, even for non-expert users. Optical hand-tracking technology allows the implementation of this immersive modeling using natural user interfaces. Here the users manipulated the virtual objects with their bare hands. In this work, we present a systematic collection of natural interactions suited for immersive building-block-based modeling systems. The interactions are conceptually described and categorized by the task they fulfil.
