In this research project, we are creating an AI environment that helps architects to identify user preferences through a Virtual Reality Interface. At the current stage of development, the project has resulted in a VR application – MuseV2 that allows users to instantly modify an architectural design. The distinctive feature of this application is that a space is considered as a base for all user modifications and as a connection between all design elements. To gather preference information, AI agents observe user-induced modifications in VR. The system that we envision should not become an automated design tool, but an adviser and viewer for novice users.
