Decoding electroencephalographic responses to visual stimuli compatible with electrical stimulation

Silvestro Micera, Simone Romeni, Laura Toni, Fiorenzo Artoni

Electrical stimulation of the visual nervous system could improve the quality of life of patients affected by acquired blindness by restoring some visual sensations, but requires careful optimization of stimulation parameters to produce useful perceptions. ...

SVGC-AVA: 360-Degree Video Saliency Prediction With Spherical Vector-Based Graph Convolution and Audio-Visual Attention

Pascal Frossard, Chenglin Li, Li Wei, Qin Yang, Yuelei Li

Viewers of 360-degree videos are provided with both visual modality to characterize their surrounding views and audio modality to indicate the sound direction. Though both modalities are important for saliency prediction, little work has been done by joint ...

Are Functional Measures Sufficient to Capture Acceptance? A Qualitative Study on Lower Limb Exoskeleton Use for Older People

Mohamed Bouri

Lower limb exoskeletons (LLE) are robotic devices developed to assist walk. In the field of healthcare, this technology has been available for almost a decade, yet it still faces important acceptance issues. While LLE were first developed for patients with ...

Multisensory haptic system and method

Olaf Blanke, Giulio Rognini, Simon Gallo

A computer-implemented method for operating a haptic device, the haptic device comprising a plurality of tactile displays configured to provide haptic stimuli to a user, the method including the steps of (a) processing an audio signal derived from an audio ...

Experimentally induced limb-disownership in mixed reality

Oliver Alan Kannape, Bigna Lenggenhager

The seemingly stable construct of our bodily self depends on the continued, successful integration of multi sensory feedback about our body, rather than its purely physical composition. Accordingly, pathological disruption of such neural processing is link ...

Deep Learning of Human Perception in Audio Event Classification

Samuel Denys Beuret, Yi Yu

In this paper, we introduce our recent studies on human perception in audio event classification. In particular, the pre-trained model VGGish is used as feature extractor to process audio data, and DenseNet is trained by and used as feature extractor for o ...

Congruent Visuo-Tactile Feedback Facilitates the Extension of Peripersonal Space

Olaf Blanke, Hannes Bleuler, Michiel van Elk, Ali Sengül

Effective tool use relies on the integration of multisensory signals related to one's body and the tool. It has been shown that active tool use results in an extension of peripersonal space, i. e., the space directly surrounding the human body. In the pres ...

Towards an implicit time-continuous assessment of Quality of Experience for immersive multimedia

Touradj Ebrahimi, Anne-Flore Nicole Marie Perrin

Quality of Experience (QoE) is a time-varying perceptual process. Despite its complexity and numerous impacting factors, recent efforts have been made to come up with subjective assessment methodologies of QoE. However, no time-continuous variant of subjec ...

Illusory hand ownership in a patient with personal neglect for the upper limb, but no somatoparaphenia

Olaf Blanke, Andrea Serino, Roberta Ronchi, Lukas Heydrich

The symptoms of patients with left personal neglect are characterized by inattention towards contralesional (left) body parts while at the same time explicitly ascertaining ownership for the neglected hemibody. It is currently unknown if personal neglect i ...

Multisensory interactions in peripersonal space and their contributions to bodily self-consciousness

Petr Grivaz

What is the relevance of the body and body-transformed sensory information for subjective experience? In the last two decades, paradigms from cognitive neuroscience have demonstrated that the subjective sensations of possessing a body (body ownership, BO), ...

The two dimensions of the body representation in women suffering from Anorexia Nervosa

Andrea Serino

A core symptom of Anorexia Nervosa (AN) is a severe alteration of body representations. Evidence from somatoperception studies point to a generic disturbances of somatosensory components of body representations. Here we have investigated whether AN patient ...

Body part-centered and full body-centered peripersonal space representations

Olaf Blanke, Hervé Lissek, Andrea Serino, Elisa Canzoneri, Patrick Marmaroli, Jean-Paul Noel

Dedicated neural systems represent the space surrounding the body, termed Peripersonal space (PPS), by integrating visual or auditory stimuli occurring near the body with somatosensory information. As a behavioral proxy to PPS, we measured participants' re ...

Moving sounds within the peripersonal space modulate the motor system

Andrea Serino, Elisa Canzoneri, Michela Bassolino

Interactions between ourselves and the external world are mediated by a multisensory representation of the space surrounding the body, i.e. the peripersonal space (PPS). In particular, a special interplay is observed among tactile stimuli delivered on a bo ...

Visual Feedback Dominates the Sense of Agency for Brain-Machine Actions

Olaf Blanke, Aaron Schurger, Nathaniel Evans, Steven Gale

Recent advances in neuroscience and engineering have led to the development of technologies that permit the control of external devices through real-time decoding of brain activity (brain-machine interfaces; BMI). Though the feeling of controlling bodily m ...

Voluntary self-touch increases body ownership

Olaf Blanke, Giulio Rognini, Masayuki Hara, Polona Pozeg

Experimental manipulations of body ownership have indicated that multisensory integration is central to forming bodily self representation. Voluntary self touch is a unique multisensory situation involving corresponding motor, tactile and proprioceptive si ...

Illusory self-identification with an avatar reduces arousal responses to painful stimuli

Olaf Blanke, Christian Pfeiffer

Looking at one's own body has been shown to induce analgesia. In the present work we investigated whether illusory self-identification with an avatar, as induced experimentally through visuo-tactile stimulation, modulates the response to painful stimuli. I ...

Crossing the hands increases illusory self-touch

Olaf Blanke, Roy Salomon, Giulio Rognini, Polona Pozeg

Manipulation of hand posture, such as crossing the hands, has been frequently used to study how the body and its immediately surrounding space are represented in the brain. Abundant data show that crossed arms posture impairs remapping of tactile stimuli f ...

Full body illusion is associated with widespread skin temperature reduction

Olaf Blanke, Roy Salomon, Roger Gassert, Christian Pfeiffer, Mei Ling Melanie Lim

A central feature of our consciousness is the experience of the self as a unified entity residing in a physical body, termed bodily self-consciousness. This phenomenon includes aspects such as the sense of owning a body (also known as body ownership) and h ...

Visuo-tactile integration and body ownership during self-generated action

Olaf Blanke, Hannes Bleuler, Roy Salomon, Giulio Rognini, Jane Aspell, Ali Sengül

Although there is increasing knowledge about how visual and tactile cues from the hands are integrated, little is known about how self-generated hand movements affect such multisensory integration. Visuo-tactile integration often occurs under highly dynami ...

Visual capture and the experience of having two bodies – Evidence from two different virtual reality techniques

Olaf Blanke, Bruno Herbelin, Jane Aspell, Lukas Heydrich

In neurology and psychiatry the detailed study of illusory own body perceptions has suggested close links between bodily processing and self-consciousness. One such illusory own body perception is heautoscopy where patients have the sensation of being redu ...
