Example Haptic Wristband Prototypes

An example of our four- and eight-motor haptic wristband prototypes examined in our GI'16 and ASSETS'17 papers. Our custom-designed wristband could accommodate wrists of various shapes and sizes. Haptic motors were placed in 3D-printed cases using magneti

Precisely guiding a blind person’s hand or finger(s) can be useful for a range of applications from tracing printed text to learning and understanding shapes and gestures. In this research project, we design, build, and study a range of novel haptic devices and actuation patterns to provide directional hand or finger guidance. We explore haptic-only solutions as well as hybrid audio+haptic approaches. We derive implications for the design of finger-worn and wrist-worn directional haptic feedback and describe open areas for future work.
