The research investigates the feasibility of applying 2D accessibility guidelines to enhance a 3D digital planning tool's accessibility for individuals with visual impairments. Three primary research questions guide this study. It incorporated a mixed-method data collection approach to comprehensively investigate these questions. The study began with a designer interview to understand the current state of accessibility within a 3D planning tool, how designers ensure compliance with guidelines, guideline adherence, and implementation strategies.Subsequently, empirical user testing was conducted involving six participants with visual impairments. This methods aimed to obtain diverse user perspectives, emphasizing the user-centered nature of the study. The designer interview highlighted four critical accessibility issues: keyboard accessibility, information clarity, clear labeling, and focus visibility. Addressing these issues aligned the 3D planning tool with WCAG 2.1 guidelines and resulted in significant enhancements in it's accessibility.Empirical user testing revealed varying degrees of success among different users with visual impairments, highlighting both the successes and challenges of implementing accessibility features, and emphasizing the complexity of designing for individuals with visual impairments. The study identified key features that contributed to an enhanced user experience, including accessibility through assistive technology, effective scanning navigation strategies, and challenges for improvements in areas such as clear descriptions and interaction feedback. This research has broader implications, impacting both the practical and scientific fields of accessibility. It offers practical significance for companies like IKEA, emphasizing the importance of a user-centered approach to empower users and gather unique insights from individuals with disabilities. Contributing inclusivity and user-friendliness in 3D planning tools.The findings highlight the significance of accessible user interface elements and the importance of compatibility with assistive technologies. A need for inclusive design methods in the development of 3D planning tools and the creation of specific accessibility guidelines designed for 3D environments. In conclusion, this research demonstrates the feasibility of applying 2D accessibility guidelines to enhance the accessibility of 3D digital planning tools. The research contributes to both practical design considerations and the scientific understanding of accessibility challenges in 3D environments.It holds the potential to improve the industry, empower users, and enhance overall accessibility standards. The findings underscore the importance of user-centered design, the complexity of designing in 3D context and to diverse user needs, the interplay between accessibility and usability, and the ongoing need for improvements to enhance the user experience, to create more inclusive and user-friendly 3D digital planning solutions for everyone.
