Abstract

ABSTRACT: Designers desire to sketch their concepts and produce prototypes in a real-time setting. This study developed a virtual reality (VR) supported lighting sketch tool for vehicle interior designers. The tool incorporated lighting design with drag-and-drop functionality and high-definition vehicle rendering. The tool also used the Wizard-of-Oz method to help design participants easily immerse themselves into the design tasks. Six designers participated in two consecutive hour-long design workshops to evaluate the design tool. Each designer sketched eight scenarios, and the workshop gathered 48 design outcomes. In addition, a thirty-minute post-interview evaluated usability, the immersive experience of the virtual environment, and the expected role of the wizard. Finally, thematic coding was used on both workshop and post-interview verbal records to further evaluate the tool's compatibility. As a result, three vital roles of the tool were identified. First, the tool encouraged the iteration process. The tool also gave realistic design-practice experiences and would be suitable for sketching lighting in the workplace. Finally, the tool allowed designers to immerse themselves in the design space. This research anticipates a well-illustrated virtual context and situations that invite designers into an inspirational lighting design workplace.
