Haptic Edge Display for Mobile Tactile Interaction
summary
A side-mounted linear array of tactile pixels uses Piezo actuators in two prototypes (initial 24-servo then a 40-pin 2-row design with 2.5mm pitch, 1.6mm pin width, up to 7mm travel) and connects via Bluetooth with four microcontrollers and a Swift app in open-loop. Pins are touch-sensitive and backdrivable to support kinesthetic and skin-level cues, dynamic affordances, and push/pull in-pocket notifications. Psychophysics give JND 0.15mm in-hand / 0.25mm in-pocket, and piezos scale to about $1 per actuator at high volume.
