DOI: 10.1109/toh.2020.3038937
Abstract: Ultrasonic surface-haptic touchscreens produce compelling tactile sensations directly on the users’ fingertips. The tactile sensations stem from the modulation of friction produced by acoustic radiation pressure, which reduces the contact between the skin and the… read more here.
