Little attention has been paid to the guidance of small-scale arm-and-hand movements by PVI, yet this is an essential element of product acquisition in a grocery shopping task and other similar daily activities. We developed a feedback interface that allowed us to explore two types of auditory feedback (speech and tones), haptic vibration feedback, and a combination of both. The result of the study demonstrated that the multi-modal navigational feedback, specifically speech and haptic, was the most effective and preferred mode for small-scale navigation.Auditory feedback | Haptic feedback | Multimodal feedback | People with visual impairmentconference paper10.1145/3132525.31348172-s2.0-85041396179https://api.elsevier.com/content/abstract/scopus_id/85041396179
