Workshops of the seventh international brain-computer interface meeting: not getting lost in translation
Kyuhwa Lee, Ricardo Andres Chavarriaga Lozano, Anton Nijholt
The Seventh International Brain-Computer Interface (BCI) Meeting was held May 21-25th, 2018 at the Asilomar Conference Grounds, Pacific Grove, California, United States. The interactive nature of this conference was embodied by 25 workshops covering topics ...
TAYLOR & FRANCIS LTD2019Novice 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 ...
2018The Critical Role of Self-Contact for Embodiment in Virtual Reality
Ronan Boulic, Bruno Herbelin, Eray Molla, Henrique Galvan Debarba, Sidney Bovet
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 ...
2018Hyperdimensional computing for noninvasive brain-computer interfaces: Blind and one-shot classification of EEG error-related potentials
The mathematical properties of high-dimensional (HD) spaces show remarkable agreement with behaviors controlled by the brain. Computing with HD vectors, referred to as "hypervectors," is a brain-inspired alternative to computing with numbers. HD computing ...
2017Hyperdimensional computing for blind and one-shot classification of EEG error-related potentials
The mathematical properties of high-dimensional (HD) spaces show remarkable agreement with behaviors controlled by the brain. Computing with HD vectors, referred to as “hypervectors,” is a brain-inspired alternative to computing with numbers. HD computing ...
Springer Verlag2017Spatial filters yield stable features for error-related potentials across conditions
José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Inaki Asier Iturrate Gil, Fumiaki Iwane
Error-related potentials (ErrP) have been increasingly studied in psychophysical experiments as well as for brain-machine interfacing. In the latter case, the generalisation capabilities of ErrP decoders is a crucial element to avoid frequent recalibration ...
2016Assimilation of virtual legs and perception of floor texture by complete paraplegic patients receiving artificial tactile feedback
Hannes Bleuler, Solaiman Shokur, Simon Gallo, Miguel Nicolelis
Spinal cord injuries disrupt bidirectional communication between the patient's brain and body. Here, we demonstrate a new approach for reproducing lower limb somatosensory feedback in paraplegics by remapping missing leg/foot tactile sensations onto the sk ...
Nature Publishing Group2016Asynchronous Decoding of Error Potentials During the Monitoring of a Reaching Task
Ricardo Andres Chavarriaga Lozano, Inaki Asier Iturrate Gil
Brain-machine interfaces (BMIs) have demonstrated how they can be used for reaching tasks with both invasive and non-invasive signal recording methods. Despite the constant improvements in this field, there still exist diverse factors to overcome before ac ...
2015Decoding Fast-Paced Error-Related Potentials in Monitoring Protocols
José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Inaki Asier Iturrate Gil, Quentin Olivier Pierre Wannebroucq
Error-related EEG potentials (ErrP) can be used for brain-machine interfacing (BMI). Decoding of these signals, indicating subject's perception of erroneous system decisions or actions can be used to correct these actions or to improve the overall interfac ...
2015Connectivity Analysis of Brain States and Applications in Brain-Computer Interfaces
Human brain is organized by a large number of functionally correlated but spatially distributed cortical neurons. Cognitive processes are usually associated with dynamic interactions among multiple brain regions. Therefore, the understanding of brain funct ...
