Haptic Stimulation

When interacting with technology, attention is mainly driven by audiovisual and increasingly haptic stimulation. Olfactory stimuli are widely neglected, although the sense of smell influences many of our daily life choices, affects our behavior, and can catch and direct our attention. In this study, we investigated the effect of smell and sound on visuospatial attention in a virtual environment. We implemented the Bells Test, an established neuropsychological test to assess attentional and visuospatial disorders, in virtual reality (VR). We conducted an experiment with 24 participants comparing the performance of users under three experimental conditions (smell, sound, and smell and sound). The results show that multisensory stimuli play a key role in driving the attention of the participants and highlight asymmetries in directing spatial attention. We discuss the relevance of the results within and beyond human-computer interaction (HCI), particularly with regard to the opportunity of using VR for rehabilitation and assessment procedures for patients with spatial attention deficits.

Exogenous Cue

An object appears smaller in the periphery than in the center of the visual field. In two experiments ( N = 24), we demonstrated that visuospatial attention contributes substantially to this perceptual distortion. Participants judged the size of central and peripheral target objects after a transient, exogenous cue directed their attention to either the central or the peripheral location. Peripheral target objects were judged to be smaller following a central cue, whereas this effect disappeared completely when the peripheral target was cued. This outcome suggests that objects appear smaller in the visual periphery not only because of the structural properties of the visual system but also because of a lack of spatial attention.

Mixed Approach

What if customer experience was the primary driver of digital transformation? Indeed, new hybrid experiences have emerged thanks to daily-life technologies that fused both digital and physical worlds. This kind of experience uses applications and connected objects (IoT) to adapt and respond to consumer needs. Augmented reality and virtual reality are one of the most functionally and emotionally memorable phygital experiences that create value for customers. In this chapter, the authors chose heritage tourism as the study field for different reasons. While the adoption of augmented and virtual reality is gaining grownd, cultural heritage sites have started to consider the possibilities offered by these new and innovative technologies. This industry is starting to integrate AR and VR in several ways to attract more people. However, it is necessary to study how modern technology can be developed and implemented in a meaningful way to improve the tourist's experience. An AR- and VR-based mobile application has been developed and tested at Antonine's Baths in Carthage, Tunisia.

Changing World

This chapter is about a redesign of mental healthcare, as it evolves in a changing world. It focuses on digital transformations and their impact on social relationships, networks, and communities. It intends to demonstrate better responses to the needs of service users in society. It first defines terminologies to access the changing world and focus on how to understand health, recovery, and well-being in people with lived experience of psychosis. These central elements can be accessed or maintained using eHealth, including mHealth, virtual reality, and eCommunities. It also discuss strengths, challenges, and pitfalls in developing and applying innovative interventions in the context of daily life. It reviews these trends and how these relate to the therapeutic relationship in general, and the mental health practitioner’s role in particular.

Measures Of Performance

The objective of the current study is to evaluate the use of virtual reality (VR) headsets to measure driving performance. This is desirable because they are several orders of magnitude less expensive than simulators and, if validated, could greatly extend the powers of simulation. Out of several possible measures of performance that could be considered for evaluating VR headsets, the current study specifically examines drivers’ latent hazard anticipation behavior both because it has been linked to crashes and because it has been shown to be significantly poorer in young drivers compared with their experienced counterparts in traditional driving simulators and in open road studies. In a between-subject design, 48 participants were equally and randomly assigned to one of four experimental conditions—two young driver cohorts (18–21 years) and two middle-aged driver cohorts (30–55 years) navigating either a fixed-based driving simulator or a VR headset-based simulator. All participants navigated six unique scenarios while their eyes were continually tracked. The proportion of latent hazards anticipated by participants which constituted the primary dependent measure, was found to be greater for middle-aged drivers than young drivers across both platforms. The difference in the magnitude of performance between the young and middle-aged drivers was similar across the two platforms. The study provides some justification for the use of VR headsets as a way of understanding drivers’ hazard anticipation behavior.
