“…They use acoustic radiation pressures obtained through the projection of focused ultrasound originated from a phased array of ultrasonic transducers directly on individuals' skin, producing a haptic sensation often described as air or breeze [14,59]. They can render dynamic patterns which induce the sensation of movement with discernible direction and localisation, which is essential for VHI induction [71,93]. The real-life RHI has successfully been replicated employing an ultrasonic mid-air haptic device.…”

“…These sensitivity differences have been partly attributed to differences in the distribution of mechanoreceptors across the arm and hand [17]. More specifically, the Meissner corpuscles, sensitive to low-frequency vibrations below 80 Hz [54], and the Pacinian corpuscles, sensitive to highfrequency vibrations ranging from 50 Hz to ten kHz [36], have both been associated with ultrasonic mid-air stimulation and are predominantly found in glabrous skin [40,71]. Hence, the tactile sensitivity to the mid-air haptic stimulation might be lower on the dorsal side resulting in higher detection thresholds on the dorsal compared to the palmar surface of the hand.…”

Ultrasonic mid-air haptic technologies, which provide haptic feedback through airwaves produced using ultrasound, could be employed to investigate the sense of body ownership and immersion in virtual reality (VR) by inducing the virtual hand illusion (VHI). Ultrasonic mid-air haptic perception has solely been investigated for glabrous (hairless) skin, which has higher tactile sensitivity than hairy skin. In contrast, the VHI paradigm typically targets hairy skin without comparisons to glabrous skin. The aim of this article was to investigate illusory body ownership, the applicability of ultrasonic mid-air haptics, and perceived immersion in VR using the VHI. Fifty participants viewed a virtual hand being stroked by a feather synchronously and asynchronously with the ultrasonic stimulation applied to the glabrous skin on the palmar surface and the hairy skin on the dorsal surface of their hands. Questionnaire responses revealed that synchronous stimulation induced a stronger VHI than asynchronous stimulation. In synchronous conditions, the VHI was stronger for palmar stimulation than dorsal stimulation. The ultrasonic stimulation was also perceived as more intense on the palmar surface compared to the dorsal surface. Perceived immersion was not related to illusory body ownership per se but was enhanced by the provision of synchronous stimulation.

“…Recent studies have used mid-air haptics to replicate traditional paradigms used in sensory experiments, such as the rubber hand illusion (Pittera et al, 2019b) and the apparent tactile motion effect (Pittera et al, 2019a). This suggests promising opportunities to use mid-air touch in other tasks involving visuotactile judgments, such as the cutaneous rabbit illusion (Geldard and Sherrick, 1972).…”

Multisensory integration research has allowed us to better understand how humans integrate sensory information to produce a unitary experience of the external world. However, this field is often challenged by the limited ability to deliver and control sensory stimuli, especially when going beyond audio–visual events and outside laboratory settings. In this review, we examine the scope and challenges of new technology in the study of multisensory integration in a world that is increasingly characterized as a fusion of physical and digital/virtual events. We discuss multisensory integration research through the lens of novel multisensory technologies and, thus, bring research in human–computer interaction, experimental psychology, and neuroscience closer together. Today, for instance, displays have become volumetric so that visual content is no longer limited to 2D screens, new haptic devices enable tactile stimulation without physical contact, olfactory interfaces provide users with smells precisely synchronized with events in virtual environments, and novel gustatory interfaces enable taste perception through levitating stimuli. These technological advances offer new ways to control and deliver sensory stimulation for multisensory integration research beyond traditional laboratory settings and open up new experimentations in naturally occurring events in everyday life experiences. Our review then summarizes these multisensory technologies and discusses initial insights to introduce a bridge between the disciplines in order to advance the study of multisensory integration.

“…Results showed that higher number of points, and longer point duration improved the reported quality of movement, which generally scored higher in the transverse direction, than the longitudinal axis. Pittera et al (2019a) also studied the illusion of movement using midair touch, stimulating both hands synchronously, such that the simulated movement is located in the intermediate space, unlike Wilson et al (2014), where tactile movement was simulated on the body.…”

“…The particle collision (see Figure 2, W1) involved two ultrasound emitters, one for each hand. A haptic impulse was displayed from one board to the other with a delay of 200 ms to create an illusion of movement (Pittera et al, 2019a). The representation involved a movement from left to right and back with a delay of 1 s (representing, respectively the clockwise and anticlockwise particle streams).…”

We explored the potential of haptics for improving science communication, and recognized that mid-air haptic interaction supports public engagement with science in three relevant themes. While science instruction often focuses on the cognitive domain of acquiring new knowledge, in science communication the primary goal is to produce personal responses, such as awareness, enjoyment, or interest in science. Science communicators seek novel ways of communicating with the public, often using new technologies to produce personal responses. Thus, we explored how mid-air haptics technology could play a role in communicating scientific concepts. We prototyped six mid-air haptic probes for three thematic areas: particle physics, quantum mechanics, cell biology; and conducted three qualitative focus group sessions with domain expert science communicators. Participants highlighted values of the dynamic features of mid-air haptics, its ability to produce shared experiences, and its flexibility in communicating scientific concepts through metaphors and stories. We discuss how mid-air haptics can complement existing approaches of science communication, for example multimedia experiences or live exhibits by helping to create enjoyment or interest, generalized to any fields of science.
