Customizing the human-avatar mapping based on EEG error related potentials during avatar-based interaction

Olaf Blanke, José del Rocio Millán Ruiz, Ronan Boulic, Bruno Herbelin, Ricardo Andres Chavarriaga Lozano, Fumiaki Iwane, Thibault Serge Mario Porssut

Objective. A key challenge of virtual reality (VR) applications is to maintain a reliable human-avatar mapping. Users may lose the sense of controlling (sense of agency), owning (sense of body ownership), or being located (sense of self-location) inside th ...

Systematic design of a multi-input multi-output controller by model-based decoupling: a demonstration on TCV using multi-species gas injection

Basil Duval, Christian Gabriel Theiler, Cristian Galperti, Artur Perek

In this paper, we present the first results of a systematically designed multi-input multi-output gas-injection controller on Tokamak a Configuration Variable (TCV). We demonstrate the simultaneous real-time control of the NII emission front position and l ...

Saliency prediction in 360° architectural scenes: Performance and impact of daylight variations

Marilyne Andersen, Sabine Süsstrunk, Caroline Karmann, Kynthia Chamilothori, Seungryong Kim, Bahar Aydemir

Saliency models are image-based prediction models that estimate human visual attention. Such models, when applied to architectural spaces, could pave the way for design decisions where visual attention is taken into account. In this study, we tested the pe ...

Human-Robot Swarm Interaction: An Explorative Path to Foster Complex Systems Understanding

Hala Khodr

Order, regularities, and patterns are ubiquitous around us. A flock of birds maneuvering in the sky, the self-organization of social insects, a global pandemic or a traffic jam are examples of complex systems where the macroscopic patterns arise from the m ...

Reaching articular limits can negatively impact embodiment in virtual reality

Olaf Blanke, Ronan Boulic, Bruno Herbelin, Thibault Serge Mario Porssut

Providing Virtual Reality(VR) users with a 3D representation of their body complements the experience of immersion and presence in the virtual world with the experience of being physically located and more personally involved. A full-body avatar representa ...

Subjective feeling of re‐experiencing past events using immersive virtual reality prevents a loss of episodic memory

Olaf Blanke, Bruno Herbelin, Lucie Bréchet, Andrea Serino, Robin Mange

Introduction: Personally meaningful past episodes, defined as episodic memories (EM), are subjectively re-experienced from the natural perspective and location of one's own body, as described by bodily self-consciousness (BSC). Neurobiological mechanisms o ...

Flight of mind: Sensorimotor and multisensory embodiment with aviation robotics, flight simulator, and virtual reality

Myeong Seop Song

Normally, humans experience an 'I' as residing in one's body and as the agent of one's actions. In other words, the self is experienced as being inside the body (self-location), as having a body (self-identification), and as being able to control the perso ...

TMS-induced control of bodily self-consciousness by combining non-invasive brain stimulation and immersive virtual reality

Matteo Franza

Our brain constantly receives and integrates a flow of sensory and motor information that shapes the way our body is represented. Several experimental approaches have been proposed to alter the body representation, by manipulating exteroceptive or interoce ...

Enhancing analgesic spinal cord stimulation for chronic pain with personalized immersive virtual reality

Olaf Blanke, Bruno Herbelin, Andrea Serino, Giulio Rognini, Marco Solcà, Robin Mange, Pavo Orepic

Spinal cord stimulation (SCS) is an approved treatment for truncal and limb neuropathic pain. However, pain relief is often suboptimal and SCS efficacy may reduce over time, requiring sometimes the addition of other pain therapies, stimulator revision, or ...

Reconciling Being in-Control vs. Being Helped for the Execution of Complex Movements in VR

Ronan Boulic, Bruno Herbelin, Thibault Serge Mario Porssut

Performing motor tasks in virtual environments is best achieved with motion capture and animation of a 3D character that participants control in real time and perceive as being their avatar in the virtual environment. A strong Sense of Embodiment (SoE) for ...

On the Influence of the Supine Posture on Simulation Sickness in Virtual Reality

Ronan Boulic

Virtual Reality (VR) has the capability of fully immersing users into a wide variety of gaming experiences where the sole focus of the user is on that experience itself. One problem that often occurs when it comes to VR experiences is that of simulation si ...

Stiffness Perception of Virtual Objects Using FOLDAWAY-Touch

Jamie Paik, Stefano Mintchev, Marco Salerno, Alexandre Thierry Cherpillod, Simone Scaduto

Haptic human interfaces are nowadays becoming more and more diffused also thanks to their combined use with Virtual Reality & Augmented Reality (VR & AR). Although many research platforms explore kinesthetic interaction with virtual objects, the only feedb ...

Novice Shooters With Lower Pre-shooting Alpha Power Have Better Performance During Competition in a Virtual Reality Scenario

José del Rocio Millán Ruiz, Michael Eric Anthony Pereira

Competition changes the environment for athletes. The difficulty of training for such stressful events can lead to the well-known effect of “choking” under pressure, which prevents athletes from performing at their best level. To study the effect of compet ...

Adequacy of Immersive Virtual Reality for the Perception of Daylit Spaces: Comparison of Real and Virtual Environments

Marilyne Andersen, Jan Wienold, Kynthia Chamilothori

This article presents a novel experimental method that uses a virtual reality (VR) headset, aiming to provide an alternative environment for the conduction of subjective assessments of daylit spaces. This method can overcome the difficulty of controlling t ...

The Critical Role of Self-Contact for Embodiment in Virtual Reality

Ronan Boulic, Sidney Bovet, Bruno Herbelin, Eray Molla, Henrique Galvan Debarba

With the broad range of motion capture devices available on the market, it is now commonplace to directly control the limb movement of an avatar during immersion in a virtual environment. Here, we study how the subjective experience of embodying a full-bod ...

Modulation of vection latencies in the full-body illusion

Olaf Blanke, Bruno Herbelin, Alessandro Nesti, Giulio Rognini

Current neuroscientific models of bodily self-consciousness (BSC) argue that inaccurate integration of sensory signals leads to altered states of BSC. Indeed, using virtual reality technology, observers viewing a fake or virtual body while being exposed to ...

Virtual Reality as a Vehicle to Empower Motor-Cognitive Neurorehabilitation

Andrea Serino

In this paper, we advocate the combination of four key ingredients that we believe are necessary to design long-lasting effective treatments for neurorehabilitation: (i) motor-cognitive training, (ii) evidence-based neuroscience principles, in particular t ...
