DEMO

We demonstrate a high-density wearable array designed for spatially localized fingertip haptics. While Linear Resonant Actuator (LRA) arrays are common in large-area wearables, applying them to the fingertip is difficult. Standard continuous vibrations trigger broad-field mechanoreceptors, causing high-density inputs to blur into a single diffuse sensation. We showcase a grid of miniature LRAs driven by a specialized control method that produces discrete, localized ``taps." Attendees will wear the device to compare this localized actuation against standard vibration and test their ability to distinguish individual contact points on the fingertip.
