“…Additionally, some of these devices allow multimodal delivery, enabling interactions beyond pairs of senses. For example, the methods by Jackowski-Ashley et al (2017) and Norasikin et al (2018) allow the integration with touch (i.e., mid-air tactile stimulation), while the approach by Norasikin et al (2019) allows visual stimulation via reconfigurable mid-air displays. This technology controls directional sound while at the same time producing a haptic sensation on the skin due to the specific frequency of the emitted sound waves.…”

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.

“…The AS effect can be measured using an anemometer [33] or estimated through numerical analysis [31]. With a typical 256 transducers array, Norasikin et al measured an airflow up to 0.8 m/s [33]. Note here that the authors were using a different algorithm than a focus algorithm, which means it is unclear what is the AS at the vicinity of an FP.…”

Ultrasound mid-air haptics has received much attention from both academic and industrial groups, however, such investigations have almost exclusively focused on the tactile stimulation of glabrous (hairless) skin of our hands. Meanwhile, the non-glabrous (hairy) part of the skin covers the largest area of our body, yet remains largely untouched and unexplored by this haptic technology. 1) We study acoustic streaming and the 2) acoustic radiation force associated with a mid-air haptic stimulus.3) We characterise the perceived strength, temperature, and definition of the stimulus through a user study. 4) Finally, in a second user study we explore the possibility of conveying affective (pleasant) touch. These objective and subjective experiments provide the first deep understanding of how mid-air haptics can affect tactile perception through stimulating the hairy skin. To that end, we discuss how researchers and haptic designers can leverage mid-air haptic technology to vary the perceived touch intensity, temperature, and deliver affective touch.

“…This technology enables the generation of arbitrary pressure fields by controlling the phases and amplitudes of each emitter. Moreover, it provides an interesting setup for a wide spectrum of novel applications, such as mid-air displays [22], wireless power transfer [23], acoustic imaging [24], or delivering food through acoustic levitation [25], to mention a few.…”

Generating Airborne Ultrasonic Amplitude Patterns Using an Open Hardware Phased Array

Holographic methods from optics can be adapted to acoustics for enabling novel applications in particle manipulation or patterning by generating dynamic custom-tailored acoustic fields. Here, we present three contributions towards making the field of acoustic holography more widespread. Firstly, we introduce an iterative algorithm that accurately calculates the amplitudes and phases of an array of ultrasound emitters in order to create a target amplitude field in mid-air. Secondly, we use the algorithm to analyse the impact of spatial, amplitude and phase emission resolution on the resulting acoustic field, thus providing engineering insights towards array design. For example, we show an onset of diminishing returns for smaller than a quarter-wavelength sized emitters and a phase and amplitude resolution of eight and four divisions per period, respectively. Lastly, we present a hardware platform for the generation of acoustic holograms. The array is integrated in a single board composed of 256 emitters operating at 40 kHz. We hope that the results and procedures described within this paper enable researchers to build their own ultrasonic arrays and explore novel applications of ultrasonic holograms.
