Designing effective user interfaces (UIs) for virtual reality (VR) is essential to enhance user immersion, usability, comfort, and accessibility in virtual environments. Despite the growing adoption of VR across domains, there is a noticeable lack of unified and comprehensive design guidelines for VR UI design. To address this gap, we conducted a systematic literature review to identify existing best practices and propose 28 unified guidelines for UI development in VR. Building on these insights, this research proposes a framework to guide the creation of more effective VR interfaces. To demonstrate and validate these practices, we developed a VR application called FlUId and an interactive Web Tool that serves as a guideline explorer and project planning resource for developers. A user study was conducted to evaluate the impact of the proposed guidelines. The findings aim to bridge the gap between theory and practice, offering concrete recommendations and digital tools for VR designers and developers.
