Abstract
Navigating unfamiliar indoor spaces is particularly challenging for blind or visually impaired (BVI) individuals due to complex layouts and inadequate signage. To address this, we introduce AccessQuotient - a metric that quantifies navigational difficulty in built environments for BVI users. Based on a simplified mathematical model and validated through a small-scale user study, AccessQuotient predicts both the likelihood of mistake-free traversal and expected navigation errors. This exploratory model aims to establish a foundation for further research rather than provide definitive assessments. By quantifying spatial complexity, AccessQuotient supports designers and planners in evaluating and improving indoor accessibility. © 2025 Copyright held by the owner/author(s).
