Environmental Factors in Indoor Navigation Based on Real-World Trajectories of Blind Users
This paper addresses a methodological blind spot in blind-navigation research: studies typically report localization accuracy and completion time, but say almost nothing about how the physical environment itself shapes where users go wrong. The autho…

Variability in Reactions to Instructional Guidance during Smartphone-Based Assisted Navigation of Blind Users
This paper takes a close, sensor-level look at something most indoor-navigation research glosses over: how differently individual blind users actually react to the same spoken instruction. The authors instrumented a smartphone-and-BLE-beacon turn-by-…

Airport Accessibility and Navigation Assistance for People with Visual Impairments
This paper investigates whether a BLE-beacon-based smartphone navigation system can enable visually impaired travelers to move through an airport independently — a setting where they are currently required to rely on airline-provided sighted escorts …

Achieving Practical and Accurate Indoor Navigation for People with Visual Impairments
This paper presents improvements to the NavCog indoor navigation system that achieve sub-meter localization accuracy for blind pedestrians while significantly reducing the infrastructure cost of deploying BLE (Bluetooth Low Energy) beacon networks. G…
