About

PneuFetch Prototype

The PneuFetch wearable prototype is composed of three parts: a pneumatic wristband, a mechanical arm-dragging mechanism, and a control armband.

PneuFetch is 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. Our contributions include: (i) an informative survey to understand what haptic feedback is preferred by BVI people for fetching nearby objects; (ii) a wearable prototype to deliver on-body touch guidance; and (iii) a preliminary user study to validate the feasibility of our approach.
