“…We selected three reference AM frequencies of 30 Hz, 80 Hz, and 210 Hz for this study. These frequencies cover the ranges commonly used in previous experiments for both mid-air ultrasound and mechanical vibrations [8,24,35,36,42,46]. Also, this choice ensured that the participants could perceive the differences among the reference AM frequencies based on a pilot study and helped keep the study session under 2 hours.…”

“…Obrist et al reported how users described the feel of two AM frequencies (16 Hz and 250 Hz) and linked the descriptions to the activation of two types of mechanoreceptors, Meissner and Pacinian corpuscles [41]. Others investigated emotional ratings and user descriptions for various design parameters of ultrasound Tactons [8,42]. Recent work has investigated ultrasound Tacton design for automotive applications [3,4].…”

“…Also, we used the single-point STM as this technique offers higher perceived intensity than multiplepoint STM [56]. Considering users' typical palm size, we rendered a circle with a radius of 10 𝑚𝑚 and a drawing speed of 12 𝑚/𝑠 at 20 𝑐𝑚 above the device, following previous work [8,13,46]. These choices aimed to ensure that all ultrasound Tactons in Studies 1-5 were perceivable by users while preventing users from perceiving the shape and the movement of the focal point trajectory.…”

Figure 1: Overview of our procedure for identifying the distinguishable temporal parameters of mid-air ultrasound Tactons. We created mid-air ultrasound Tactons using temporal parameters. People felt all pairs of the Tactons using the ultrasound haptic device and rated the perceptual similarity of the Tactons. Finally, we derived perceptual dissimilarity spaces and identified the dominant parameters for distinguishable ultrasound Tactons.

In virtual reality (VR), users live real-life experiences that can be studied as such. We first present two studies in which we collected the lived experiences of participants using micro-phenomenological interviews. We then modeled and compared these descriptions of experiences. The first study focuses on experiences associated with an ophthalmology ambulatory journey in VR, while the second one pertains to those associated with alternative decision-making during a cooking task in VR. We then present and discuss the main insights we derive from these two studies: micro-phenomenological interviews are adapted to collect lived experience in VR; the analysis of these interviews benefits from data collected in VR; "sensory anchors" facilitate the conduct of micro-phenomenological interviews and their analysis; the VR experience collected through micro-phenomenological interview primarily concerns the task.

Predicting how the fingertip will mechanically respond to different stimuli can help explain human haptic perception and enable improvements to actuation approaches such as ultrasonic mid-air haptics. This study addresses this goal using high-fidelity 3D finite element analyses. We compute the deformation profiles and amplitudes caused by harmonic forces applied in the normal direction at four locations: the center of the finger pad, the side of the finger, the tip of the finger, and the oblique midpoint of these three sites. The excitation frequency is swept from 2.5 to 260 Hz. The simulated frequency response functions (FRFs) obtained for displacement demonstrate that the relative magnitudes of the deformations elicited by stimulating at each of these four locations greatly depend on whether only the excitation point or the entire finger is considered. The point force that induces the smallest local deformation can even cause the largest overall deformation at certain frequency intervals. Above 225 Hz, oblique excitation produces larger mean displacement amplitudes than the other three forces due to excitation of multiple modes involving diagonal deformation. These simulation results give novel insights into the combined influence of excitation location and frequency on the fingertip dynamic response, potentially facilitating the design of future vibration feedback devices.
