“…These new olfactory devices make use of advances in sensors (e.g., biometric and wearable sensors) and enable thinking beyond the constraints of unisensory stimulation. For example, wearable scent delivery systems have been used to modulate the perception of temperature ( Brooks et al, 2020 ), which can enable the study of multisensory integration involving olfactory and somatosensory signals ( de la Zerda et al, 2020 ).…”

“…Furthermore, since wearable scent delivery systems are small and portable, they can easily be integrated with additional multisensory technology and other actuators. For example, Brooks et al (2020) used a wearable smell delivery device attached to a VR headset to show visual stimuli as well. Moreover, Ranasinghe et al (2018) added sensory stimulation, such as wind and thermal feedback to provide a multisensory experience and thus induce a sense of presence.…”

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.

“…In mixed reality, an example is MetaCookie, a system that augments a cookie's flavor by digitally overlapping colors and textures, as well as specific aromas, on a plain cookie (Narumi et al, 2011). Finally, an example on the virtual end of the reality-virtuality continuum, is presented by Brooks et al (2020), who developed a 'thermal display' that, through scents that evoke characteristic trigeminal sensation, integrates thermal sensations into virtual reality.…”

We present a primer on multisensory experiences, the different components of this concept, as well as a reflection of its implications for individuals and society. We define multisensory experiences, illustrate how to understand them, elaborate on the role of technology in such experiences, and present the three laws of multisensory experiences, which can guide discussion on their implications. Further, we introduce the case of multisensory experiences in the context of eating and human-food interaction to illustrate how its components operationalize. We expect that this article provides a first point of contact for those interested in multisensory experiences, as well as multisensory experiences in the context of human-food interaction.

“…Besides the cutaneous sensations, researchers also looked into other sensory channels to create, for instance, scent stimulus via a near nose olfactory interface [92]. Recently, Brooks et al [7] demonstrated emitting certain scents to create temperature illusion via stimulating the trigeminal nerve. This work is similar to ours in the way that both consider using chemical stimulants.…”

“…Different from these, Douleur explores the feasibility and effects of leveraging chemical stimulant -capsaicin to create pain sensations on skin without causing injuries. Capsaicin was used in Brooks et al [7], but their purpose was to create hot temperature illusion by emitting chemical stimulants to the air close to the user's nose. Sabien et al [90] used high-concentration topical capsaicin to study whether the changes in thermal sensitivity induced by the capsaicin can be explained entirely by desensitization of capsaicin-sensitive afferents.…”

The imitation of pain sensation in Virtual Reality is considered valuable for safety education and training but has been seldom studied. This paper presents Douleur, a wearable haptic device that renders intensity-adjustable pain sensations with chemical stimulants. Different from mechanical, thermal, or electric stimulation, chemical-induced pain is more close to burning sensations and long-lasting. Douleur consists of a microfluidic platform that precisely emits capsaicin onto the skin and a microneedling component to help the stimulant penetrate the epidermis layer to activate the trigeminal nerve efficiently. Moreover, it embeds a Peltier module to apply the heating or cooling stimulus to the affected area to adjust the level of pain on the skin. To better understand how people would react to the chemical stimulant, we conducted a first study to quantify the enhancement of the sensation by changing the capsaicin concentration, skin temperature, and time and to determine suitable capsaicin concentration levels. In the second study, we demonstrated that Douleur could render a variety of pain sensations in corresponding virtual reality applications. In sum, Douleur is the first wearable prototype that leverages a combination of capsaicin and Peltier to induce rich pain sensations and opens up a wide range of applications for safety education and more.
