A Low-Cost Multi-Modal Auditory-Visual-Tactile Framework for Remote Touch
2020
International audience; Haptic technology for human augmentation provides gains in ability for different applications, whether the aim is to enhance "disabilities" to "abilities", or "abilities" to "super-abilities". Commercially-available devices are generally expensive and tailored to specific applications and hardware. To give researchers a haptic feedback system that is economical, customisable, and fast to fabricate, our group developed a low-cost immersive haptic, audio, and visual experience built by using off-the-shelf (COTS) components. It is composed of a vibrotactile glove, a Leap Motion sensor, and an head-mounted display, integrated together to provide compelling immersive sens…
Optical See-Through Head-Mounted Displays With Short Focal Distance: Conditions for Mitigating Parallax-Related Registration Error
2020
Optical see-through (OST) augmented reality head-mounted displays are quickly emerging as a key asset in several application fields but their ability to profitably assist high precision activities in the peripersonal space is still sub-optimal due to the calibration procedure required to properly model the user's viewpoint through the see-through display. In this work, we demonstrate the beneficial impact, on the parallax-related AR misregistration, of the use of optical see-through displays whose optical engines collimate the computer-generated image at a depth close to the fixation point of the user in the peripersonal space. To estimate the projection parameters of the OST display for a …
Blending in Hybrid Games: Understanding Hybrid Games Through Experience
2016
The meaning of what hybrid games are is often fixed to the context in which the term is used. For example, hybrid games have often been defined in relation to recent developments in technology. This creates issues in its usage and limitations in thinking. This paper argues that hybrid games should be understood through conceptual metaphors. Hybridity is the blending of different cognitive domains that are not usually associated together. Hybrid games usually blend domains related to games, for example digital and board games, but can blend also other domains. Through this type of thinking, designers can be more open to exploring how their games can be experienced.
La intimidad corporal en la filosofía de Ortega y Gasset
2015
[EN] In the face of the social crisis of intimacy for the extimacy, in neurosciences, and its reduction to privacy in legal field, this article explains the orteguian idea of the intimacy highlighting its bodily character. This notion of intimacy, rooted in body, discovers the sentimental aspect of reality (lyricism), and also overcomes thingism and subjectivism through the analysis of the mechanism of metaphor and the capacity of entering yourself. Reality of intimacy is conceived as enforceability (executive reality), and represents an alternative to idealism, objetivism of conscience and psychological introspection.
More than experience? On the unique opportunities of virtual reality to afford a holistic experiential learning cycle
2021
Virtual reality has been proposed as a promising technology for higher education since the combination of immersive and interactive features enables experiential learning. However, previous studies did not distinguish between the different learning modes of the four-stage experiential learning cycle (i.e., concrete experience, reflective observation, abstract conceptualization, and active experimentation). With our study, we contribute a deeper understanding of how the unique opportunities of virtual reality can afford each of the four experiential learning modes. We conducted three design thinking workshops with interdisciplinary teams of students and lecturers. These workshops resulted in…
The Role of Searle's Constitutive Rules for the Rational Criticizability of Institutional Reality
2013
My hypothesis is that we can derive the normative conditions that institutions and institutional acts have to meet in order to be rationally acceptable/recognizable from the logical structure of institutional reality. Developing Searle's achievements on the constitutive role of speech acts in the construction of institutional reality and on their character of institutional acts, I'll show that the same types of constitutive rules underlying illocutionary acts also underlie institutional reality. I’ll then argue that we can derive a specific set of normative criteria for the rational criticizability of institutional acts from these constitutive rules in the same way that we can derive normat…
Providing Psychological and Emotional Support After Perinatal Loss: Protocol for a Virtual Reality-Based Intervention
2020
The loss of an infant during the perinatal period has been recognized as a complex and potentially traumatic life event and can have a significant impact on women’s mental health. However, often times, psychological aftercare is typically not offered, and manualized interventions are rarely used in clinical care practice and have seldom been evaluated. In recent years, a growing number of studies have demonstrated the efficacy of virtual reality (VR) interventions to facilitate the expression and coping with emotions linked to a traumatic event. The objective of the proposed paper is to present the protocol of a randomized control trial aimed to assess a novel VR-based intervention for moth…
Low dose CT of the heart: a quantum leap into a new era of cardiovascular imaging.
2010
In 10 years, computed tomography coronary angiography (CTCA) has shifted from an investigational tool to clinical reality. Even though CT technologies are very advanced and widely available, a large body of evidence supporting the clinical role of CTCA is missing. The reason is that the speed of technological development has outpaced the ability of the scientific community to demonstrate the clinical utility of the technique. In addition, with each new CT generation, there is a further broadening of actual and potential applications. In this review we examine the state of the art on CTCA. In particular, we focus on issues concerning technological development, radiation dose, implementation,…
From virtual to real healing: a critical overview of the therapeutic use of virtual reality to cope with mourning
2021
In recent years, virtual reality (VR) has been effectively employed in several settings, ranging from health care needs to leisure and gaming activities. A new application of virtual stimuli appeared in social media: in the documentary 'I met you' from the South-Korean Munhwa Broadcasting, a mother made the experience of interacting with the avatar of the seven-year-old daughter, who died four years before. We think that this new application of virtual stimuli should open a debate on its possible implications: it represents contents related to grief, a dramatic and yet natural experience, that can have deep psychological impacts on fragile subjects put in virtual environments. In the presen…
Digitalization and sustainability: virtual reality tourism in a post pandemic world
2022
The government-imposed COVID-19 pandemic control measures brought the tourism sector to a complete halt. However, virtual reality (VR) tourism offered people a way to escape the isolation. Media reports and research have noted heightened activity in VR tourism, which has been touted as “alternative tourism” and “eco-tourism”. However, scholars have yet to determine whether this shift is temporary or will persist after the pandemic is over. Questions also remain regarding the factors driving this behaviour. The present study uses stimulus-organism-response theory (SOR) to propose a sequential mechanism of the interplay of antecedents and outcomes, theorising VR tourism as a sustainable touri…
