The aim of this study is to provide a comprehensive test of three spatial speller settings, for the auditory, visual, and audiovisual paradigms. For rigour, the study is conducted with 16 BCI-na\"ive subjects in an experimental set-up based on five Japanese hiragana characters. Auditory P300 responses give encouragingly longer target vs. non-target latencies during the training phase, however, real-world online BCI experiments in the multimodal setting do not validate this potential advantage… 

Figures and Tables from this paper

Classification improvement of P300 response based auditory spatial speller brain-computer interface paradigm
TLDR
The case study is presented indicating that the auditory spatial unimodal paradigm classification accuracy can be enhanced with an AUC based feature selection approach, as far as BCI-naive healthy subjects are concerned.
Auditory Brain-Computer Interface Paradigm with Head Related Impulse Response-Based Spatial Cues
TLDR
The case study indicated that the auditory HRIR spatial sound reproduction paradigm could be a viable alternative to the established multi-loudspeaker surround sound BCI-speller applications, as far as healthy pilot study users are concerned.
Two-step Input Spatial Auditory BCI for Japanese Kana Characters
TLDR
An auditory stimulus optimization and a pilot study of a two-step input speller application combined with a spatial auditory brain–computer interface (saBCI) for paralyzed users confirm the effectiveness of the proposed spelling method.
Spatial Auditory Brain-computer Interface using Head Related Impulse Response
TLDR
It is indicated that the headphone reproduced auditory (HRIR- based) spatial sound paradigm could be a viable alternative to the established multi-loudspeaker surround sound BCI-speller applications, as far as healthy pilot study users are concerned.
Head-related Impulse Response-based Spatial Auditory Brain-computer Interface
TLDR
It is indicated that the auditory HRIR spatial sound paradigm reproduced with headphones could be a viable alternative to established multi– loudspeaker surround sound BCI–speller applications.
Head-related impulse response cues for spatial auditory brain-computer interface
TLDR
The saBCI accuracy and information transfer rate (ITR) scores have been improved comparing to the classical horizontal plane-based virtual spatial sound reproduction modality, as far as the healthy users in the current pilot study are concerned.
Novel virtual moving sound-based spatial auditory brain-computer interface paradigm
TLDR
The concept of moving sound proposed and tested in the paper allows for the creation of a P300 oddball paradigm of necessary target and non-target auditory stimuli, which are more interesting and easier to distinguish.
Brain-computer interface using ambisonics-reproduced dynamic sound image effects
TLDR
The online classification of the P300 response proves the reliability of the proposed method and it confirms advantages of such system compared to the state-of-the art auditory static sound-based spatial auditory BCI paradigms.
Beyond visual P300 based brain-computer interfacing paradigms
TLDR
The paper reviews and summarizes recent developments in spatial auditory and tactile brain-computer interfacing neurotechology applications and presents and reviews the EEG event related potential responses useful for brain computer interfacing applications beyond state-of-the-art visual paradigms.
