The viewing experience of 3D artifacts in Virtual Reality (VR) museums is constrained and affected by various factors, such as pedestal height, viewing distance, and object scale. User experiences regarding these factors can vary subjectively, making it difficult to identify a universal optimal solution. In this paper, we collect empirical data on user-determined parameters for the optimal viewing experience in VR museums. By modeling users' viewing behaviors in VR museums, we derive predictive functions that configure the pedestal height, calculate the optimal viewing distance, and adjust the appropriate handheld scale for the optimal viewing experience. This led to our novel 3D responsive design, ResponsiveView. Similar to the responsive web design that automatically adjusts for different screen sizes, ResponsiveView automatically adjusts the parameters in the VR environment to facilitate users' viewing experience. The design has been validated with two popular inputs available in current commercial VR devices: controller-based interactions and hand tracking, demonstrating enhanced viewing experience in VR museums.
