Mid-Air Ultrasonic Stimulations of the Palm - The Influence of Frequency and Stimulus Duration on Perceived Intensity

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...
