(TU Delft Human Information Communication Design) Frier, William (Ultrahaptics, Glass Wharf, Bristol BS20EL, UK) Pont, S.C. (TU Delft Human Information Communication Design) Hartcher-O'Brien, J. (TU Delft Human Information Communication Design) Contributor Shinoda, Hiroyuki (editor) Kajimoto, Hiroyuki (editor) Date 2019 Abstract It is known that the duration of a short stimulus affects the perceived intensity of both visual, auditory, and, vibrotactile events, but it is still unclear whether such a relationship also exists for mid-air ultrasonic inputs to the hand. Here we investigate this issue and show how the perceived intensity of focused ultrasonic stimulations of the palm is indeed systematically related to stimulus duration - a relationship that is, however, independent of modulation frequency. This is an important finding for the overall goal of providing perceptually stronger inputs and enlarging the repertoire of realistic mid-air haptic experiences.
