Novel paradigms for auditory P300 Spellers with spatial hearing: two online studies.
Using Brain-computer interfaces (BCI) one can establish a communication pathway which does not rely on muscular activity. This is a promising tool for patients suffering from neurodegenerative diseases like amyotrophic lateral sclerosis (ALS). Since visual BCI paradigms might not be eligible for those patients , auditory speller paradigms were recently investigated [2-3]. Spatial hearing has been introduced as informative cue in a BCI paradigm , revealing that subjects are able to focus attention to a target direction. Two online studies investigate the usability of speller paradigms with spatial auditory cues.
