Development and Evaluation of the Virtual Prototype of the First Saudi Arabian-Designed Car

Prototyping and evaluation are imperative phases of the present product design and development process. Although digital modeling and analysis methods are widely employed at various product development stages, still, building a physical prototype makes the present typical process expensive and time consuming. Therefore, it is necessary to implement new technologies, such as virtual prototyping, which can enable industry to have a rapid and more controlled decision making process. Virtual prototyping has come a long way in recent years, where current environments enable stereoscopic visuals, surround sound and ample interaction with the generated models. It is also important to evaluate how representative the developed virtual prototype is when compared to the real-world counterpart and the sense of presence reported by users of the virtual prototype. This paper describes the systematic procedure to develop a virtual prototype of Gazal-1 (i.e., the first car prototype designed by Saudi engineers) in a semi-immersive virtual environment. The steps to develop a virtual prototype from CAD (computer-aided design) models are explained in detail. Various issues involved in the different phases for the development of the virtual prototype are also discussed comprehensively. The paper further describes the results of the subjective assessment of a developed virtual prototype of a Saudi Arabian-designed automobile. User's feedback is recorded using a presence questionnaire. Based on the user-based study, it is revealed that the virtual prototype is representative of the real Saudi Arabian car and offers a flexible environment to analyze design features when compared against its physical prototype. The capabilities of the virtual environment are validated with the application of the car prototype. Finally, vital requirements and directions for future research are also presented.

“…The instrument panel was chosen because drivers used it most frequently when they were in the car and the design of instrument panel has been evaluated for checking the interior styles of cars in terms of impressions, functionality, and usability (Cho & Lee, ; Shen, Chen, Liang, Pu, & Ma, ). Likewise, door‐trim armrest and A‐pillar were selected because they were not only frequently used by drivers but also they have been investigated as critical areas of automobile interior design (Kim, Lee, Lehto, & Yun, ; Soderberg, Lindkvist, & Carlson, ). In addition, instrument panel, door‐trim armrest, and A‐pillar are proper to apply illusory design elements because they are perceived as objects having multiple character lines and geometric shapes.…”

Perceived Interior Space of Motor Vehicles based on Illusory Design Elements

et al. 2014

Driver and passengers recognize the interior spaces of cars psychologically as well as physically. Since the car companies have difficulty extending the physical spaces of cars due to the cost and physical constraints, they tend to make an effort to widen the perceived space instead of the physical space. In this study, we aim to investigate the effectiveness of car interior designs to which optical illusions are applied to increase their perceived roominess. Instrument panels, door-trim armrests, and A-pillars were chosen as the interior spaces of cars that optical illusions were applied to because drivers most frequently recognize and use them. To get alternative car interior designs, the original car designs were modified by applying optical illusions. Also, the questionnaire that includes 28 questions was used to measure "perceived roominess," "space completeness," "openness," "dullness," and "narrowness" for original interior design and alternative designs based on optical illusions, and 30 people participated in the experiments that were conducted to compare among original and optical illusion-based designs. As a result, optical illusion-based designs were significantly better than original designs in terms of perceived roominess, and the following alternative designs were recommended: the instrument panel design of a 30% longer converging point than the original design, the horizontal door-trim armrest design, and the A-pillar design whose cross section is rectangular. We can conclude that the optical illusions can be applied to designing in-vehicle spaces to increase perceived roominess. C 2014 Wiley Periodicals, Inc.

Crucial issues for product designers include how to capture consumers’ attention, evoke their pleasurable preferences, and affect their purchase decisions. In this article, we focus on consumers’ affective preferences in relation to visual ergonomics to propose a new hybrid consumer‐oriented model using gray relational analysis (GRA), gray prediction (GP), and the technique for order preference by similarity to ideal solution (TOPSIS). The GRA is used to identify the most influential elements of the product form to help product designers focus their attention more on these elements without compromising the predictive performance. The GP is used in conjunction with the GRA to obtain a better structure for the hybrid consumer‐oriented model, and TOPSIS is performed to determine the optimal alternatives for best matching consumers’ affective preferences. These experimental results show that the new hybrid consumer‐oriented model incorporated with the CAD/CAM system can facilitate the product affective design process.
