Overcoming Barriers in Noninvasive Brain-Computer Interfaces

摘要: Although many advances in brain-computer interface (BCI) technology have been made in recent years, there are still a number of barriers that continue to impede the widespread adoption of BCI into commercial devices. At The Colorado State University Brain-Computer Interface Laboratory, we are taking a practical, multifaceted approach toward addressing these issues.The bulk of our research is focused on improving two BCI paradigms: P300 spellers and classification of imagined mental tasks. We believe that improvements in P300 spellers may have an immediate impact on assistive technology while the classification of spontaneous imagined mental tasks may lead to a stimulus-free BCI that can be operated fluidly and with multiple degrees of freedom. In the following sections, we outline the research we are currently performing to overcome the obstacles associated with implementing these paradigms.
