Older Pedestrians Navigating With AR Glasses and Bone Conduction Headset

摘要

Designing navigation aids for older pedestrians could help them stay autonomous in their daily activities. Here we present a description of the navigation experience of older pedestrians either with a visual (augmented reality glasses) or an auditory (bone conduction headset) wearable device providing guidance messages adapted to age-related declines. The study, with 18 participants, analyses the navigation performance and users' experience using explicitation interviews. We highlight that sharing attention, trusting the system temporality and experiencing the discretion of the device are the main concerns for older people, impacting the quality of their user experience. These findings are discussed in terms of design recommendations for digital devices.
