PneuFetch: Supporting Blind and Visually Impaired People to Fetch Nearby Objects via Light Haptic Cues
Liang He, Ruolin Wang, Xuhai Xu
We present PneuFetch, a light haptic cue based wearable device that supports blind and visually impaired (BVI) people to fetch nearby objects in an unfamiliar environment. In our design, we generate friendly, non-intrusive, and gentle presses and drags to deliver direction and distance cues on BVI user’s wrist and forearm. As a concept of proof, we discuss our PneuFetch wearable prototype, contrast it with past work, and describe a preliminary user study.
