“…It is common to use those spatial perception measures which are appropriate for the specific topic of interest within the certain domain. For example, dimensions when analyzing 3D CAD models [34] or body-scaled affordances when detecting the shortcomings of a room layout [35]. For reporting judgments or estimations to assess spatial perception when performing respective tasks in the experiments, extrinsic and intrinsic metrics have been employed.…”

“…When investigating spatial perception in VEs, scholars in the AEC domains often focus on spatial properties such as dimensions of objects or distances between several objects. For example, Gîrbacia et al [34] conducted an experiment with the aim of analyzing depth perception of reviewed 3D CAD models (assembled from parallelepiped parts) in IVE and nIVE. Depth estimation was verbal, expressed in extrinsic metrics (centimeters) and based on comparison with the known size of the virtual table on which 3D CAD models were positioned.…”

“…In the engineering domain, studies related to spatial perception in VEs have been conducted with different goals (such as usage of IVEs for requirements validation [38], an inspection of a room layout [35], or an analysis of depth perception of reviewed 3D CAD models [34]) and employing various methods (for example, verbal estimations reported in extrinsic metrics [17], [34], identification of correct values of spatial properties [24] or action-based tests of locating an object in a VE [36]). Due to these differences among the studies, the findings they report are anchored to the context of their specific cases.…”

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.

“…First, good immersion allows for a better perception of the environment. As a matter of fact, it has been shown that users estimate the depth of 3D models with greater accuracy using stereoscopic immersive systems compared to traditional display systems [20]. Second, immersion enhances the sense of presence especially by real-time user tracking and by visual feedback of the user's hands and body [21], [22].…”

Abstract-This paper discusses the potential benefits of applying Virtual Reality (VR) technology to the context of Systems Engineering (SE), for both educational and industrial purposes.After an introductive presentation of the two fields and their state of the art, we explore if and how VR can be of assistance to the processes involved in a typical SE approach. We especially focus on commonly used 3D interaction techniques in VR and argue that the design of appropriate 3D interactions is a key ingredient for the success of VR in SE. We suggest three research directions that may be considered for this design: interaction generality, context awareness and adaptability. The 3D interactions should adapt, manually or automatically, to the VR device, the virtual scene and the user context. Index Terms-Virtual reality, virtual environment, systems engineering, 3d interaction, adaptive interaction.

“…The technology that exists today is enabling the usage of analysis and simulation in order to optimise product and processes before the actual production and assembly. Virtual prototypes can also be used to verify does the product comply with the customer requirements (Gîrbacia et al, 2012;Zhiyong et al, 2012). Manufacturing has to be aligned with the design activities.…”

Automotive manufacturers are experiencing difficulties in hiring highly qualified workers with ability to adopt new technologies fast. This kind of ongoing need for training is slowing innovation. This problem is related to the difficulty in obtaining consistent training resources and services especially with lack of training for advanced manufacturing practices for specialised industry sectors. More and more occupations require degrees higher than secondary education because of the global need for so called 'knowledge workers'. An example of an interactive learning programme, developed with the support of narrated presentation technology, podcasts and online access has been shown in this paper. Sixty nine online modules have been developed during the course of a project funded by Department of Labor for automotive sector. These online modules have been developed for lifelong learners to be used and accessed at any time (asynchronously from a website). Curriculum modules, developed for the Introduction to Digital Manufacturing are a part of a certificate programme which expands the pool of skilled workers, enhance the abilities of incumbent workers, and strengthen the entire advanced manufacturing sector.
