Haptic-Augmented AV Experiences: Potentials for Blind and Low-Vision Users

Haptic technology has diverse applications in automated vehicles (AVs), yet research lacks a holistic view of its role in user experiences and its inclusive potential for blind and low-vision (BLV) users. This paper reviews state-of-the-art haptic interfaces in AVs, examining technological foundations, applications, user experience considerations, and adaptability for BLV accessibility. We found that existing haptic interfaces are primarily designed for drivers during automation transitions, emphasizing effectiveness over hedonic experience. There is a knowledge gap in how such interfaces can improve BLV user experience in fully automated vehicles. We propose a shift from haptic-supported automated driving to Haptic-Augmented AV Experiences, advocating for more inclusive and adaptive haptic interactions beyond traditional driver-centric paradigms.
