An auditory brain-computer interface (BCI).
Brain-computer interfaces (BCIs) translate brain activity into signals controlling external devices. BCIs based on visual stimuli can maintain communication in severely paralyzed patients, but only if intact vision is available. Debilitating neurological disorders however, may lead to loss of intact vision. The current study explores the feasibility of an auditory BCI. Sixteen healthy volunteer...
متن کاملIs an auditory P300-based Brain-Computer Musical Interface feasible?
One of the most robust ways of building a voluntarily controlled BCI that wouldnt require almost any training on behalf of the user, is through the P300 potential. In this study we implemented and evaluated a simple auditory P300-based musical interface. The interface consists of a dynamic 5-class auditory oddball paradigm. Each stimulus is tuned to a specific note, forming a part of a chord. A...
متن کاملAn online brain-computer interface based on shifting attention to concurrent streams of auditory stimuli.
We report on the development and online testing of an electroencephalogram-based brain-computer interface (BCI) that aims to be usable by completely paralysed users-for whom visual or motor-system-based BCIs may not be suitable, and among whom reports of successful BCI use have so far been very rare. The current approach exploits covert shifts of attention to auditory stimuli in a dichotic-list...
متن کاملAn auditory oddball brain-computer interface for binary choices.
OBJECTIVE Brain-computer interfaces (BCIs) provide non-muscular communication for individuals diagnosed with late-stage motoneuron disease (e.g., amyotrophic lateral sclerosis (ALS)). In the final stages of the disease, a BCI cannot rely on the visual modality. This study examined a method to achieve high accuracies using auditory stimuli only. METHODS We propose an auditory BCI based on a th...
متن کاملAffective Stimuli for an Auditory P300 Brain-Computer Interface
Gaze-independent brain computer interfaces (BCIs) are a potential communication tool for persons with paralysis. This study applies affective auditory stimuli to investigate their effects using a P300 BCI. Fifteen able-bodied participants operated the P300 BCI, with positive and negative affective sounds (PA: a meowing cat sound, NA: a screaming cat sound). Permuted stimuli of the positive and ...
