Safe Local Navigation for Visually Impaired Users With a Time-of-Flight and Haptic Feedback Device.
IEEE Transactions on Neural Systems and Rehabilitation Engineering(2018)
摘要
This paper presents ALVU (Array of Lidars and Vibrotactile Units), a contactless, intuitive, hands-free, and discreet wearable device that allows visually impaired users to detect low- and high-hanging obstacles, as well as physical boundaries in their immediate environment. The solution allows for safe local navigation in both confined and open spaces by enabling the user to distinguish free spac...
