VRArchEducation: Redesigning building survey process in architectural education using collaborative virtual reality

Architectural education requires students to work as a group under the supervision of a teacher in the same physical environment since they need interaction to learn how to do a set of measurements in practice. However, a number of obstacles, such as pandemic situations, weather conditions, and the crowdedness of working sites, do not allow them to be and work together in a physical environment. Existing digital solutions, such as online and distance education, do not provide the required immersive and collaborative learning environment to assist students to practice in the same virtual environment. Therefore, the main aim of this study is to develop an immersive architectural educational environment, named VRArchEducation, using Virtual Reality (VR). Specifically, we design and implement a system that allows students and teachers to enjoy direct and simultaneous interaction through their virtual avatars regardless of their current physical location. Furthermore, the proposed VRArchEducation will enable users to have hands-on immersive experience while performing a set of measurement tasks. VRArchEducation presents four virtual fundamental measurement tools: water level hose, plumb, measurement tape, and a sketching board. Using these tools, students can perform a building survey process together in the VRArchEducation system just like in a traditional class environment. We conduct a user study to evaluate the system’s effectiveness, success, accuracy, and usability. The proposed VRArchEducation has a great potential to be used in architectural education as an alternative to the traditional environment.
