“…Various digital artefacts being developed also convey touch to enrich VR experiences including gloves (e.g. HaptX, Gu et al 2016); enhanced controllers through attached vibrotactile motors (e.g. Lee et al 2019) or mechanically actuators enabling users to feel the shape of virtual objects (Benko et al 2016); tactile sensations on the hand using mid-air tactile stimulation (Pittera et al 2019); 'plasters' using SMA technology (shape-memory alloys) "recreating the perception of a touch sensation on the forearm (e.g.…”

How touch is conceptualised matters in shaping technical advancements, bringing opportunities and challenges for development and design and raising questions for how touch experience is reconfigured. This paper explores the notion of touch in virtual reality (VR). Specifically, it identifies how touch ‘connection’ is realised and conceptualised in virtual spaces in order to explore how digital remediation of touch in VR shapes the sociality of touch experiences and touch practices. Ten participants from industry and academia with an interest in touch in virtual contexts were interviewed using an in-depth semi-structured approach to elicit experiences and perspectives around the role of touch in VR. Data analysis shows the growing value and significance of touch in virtual spaces and reveals particular ways in which touch is talked about, implemented and conceptualised. It highlights changes for the sociality of touch through participants’ conceptualisations of touch as replication and illusion, and how the body is brought into this ‘touch’ space. These perspectives of touch shape who touches, what is touched and how it is touched and set an agenda for the types of touch that are facilitated by VR. The findings suggest ways in which technological techniques can be employed towards interpretive designs of touch that allow for new ways to look at touch and haptics. They also show how touch is distorted and disrupted in ways that have implications for disturbing established ‘real world’ socialities of touch as well as their renegotiation by users in the space of digitally mediated touch in VR.

“…Newer rendering methods, such as spatio-temporal modulation, would do this in a different way and may give different results. For example, work by Hajas et al [67] into 'dynamic tactile pointers' suggest considerable nuance is required to render easily identifiable 2D polygons using spatiotemporal modulation. It is, therefore, important for researchers to consider the capabilities of the technologies they are using when looking at past results.…”

“…TH-2020-01-0010 5 more complicated, as changes in direction between edges may be difficult to perceive. Hajas et al [67] investigated the use of a "dynamic tactile pointer", intended to emphasize the discrete edges that constitute a polygon by pausing at the vertices (e.g., the four corners of a rectangle). Their method improved perception, leading to a recommendation that polygons are rendered as discrete edges rather than a continuous outline with a uniform movement speed.…”

Ultrasound haptics is a contactless haptic technology that enables novel mid-air interactions with rich multisensory feedback. This paper surveys recent advances in ultrasound haptic technology. We discuss the fundamentals of this haptic technology, how a variety of perceptible sensations are rendered, and how it is currently being used to enable novel interaction techniques. We summarize its strengths, weaknesses, and potential applications across various domains. We conclude with our perspective on key directions for this promising haptic technology.

“…Bridging this gap could open up a wide range of new studies exploring the integration of multiple senses with mid-air touch using the technology recently developed in HCI and further taking advantage of the current knowledge generated in this area. For example, a number of studies have already provided insights that improve our understanding of mid-air haptic stimuli perception in terms of perceived strength (Frier et al, 2019), geometry identification (Hajas et al, 2020b), and tactile congruency (Pittera et al, 2019b), providing compelling evidence of the capability of mid-air haptics to convey information (Hajas et al, 2020a;Paneva et al, 2020).…”

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.
