Pulp Friction - Exploring the Finger Pad Periphery for Subtle Haptic Feedback

Explore a novel haptic feedback technique that applies stimuli around the periphery of the finger pulp in this 22-minute conference talk from the ACM CHI Conference on Human Factors in Computing Systems. Discover how this approach provides rich, nuanced haptic information using a reconfigurable device with a ferromagnetic marble for back-of-device handheld use. Learn about the design space, human factors, and potential applications of finger-peripheral touch interaction through a controlled user study. Gain insights into the effectiveness of different marble diameters, speeds, and stimulation patterns, including poking and lateral vibration. Understand the resulting design guidelines for finger-periphery haptic feedback and explore potential use case scenarios that demonstrate the technique's versatility.
