Interventions
BEHAVIORAL

BCI-FIT multi-modal access

Adding a personalized multi-modal access protocol to customize a BCI-FIT access method configuration for each individual end user, based on a combination of user characteristics, clinical expertise, user feedback, and system performance data in the software.

BEHAVIORAL

BCI-FIT adaptive signal modeling

Adding a BCI-FIT adaptive signal modeling that employs transfer learning and on-line model adaptation techniques with noisy labels in the software of this brain-computer interface to eliminate the need for data collection exclusively for model calibration, as well as to address model drift issues associated with drowsiness, fatigue, and other human and environmental factors.

BEHAVIORAL

BCI-FIT active querying

Adding BCI-FIT active querying techniques which are software-based optimal action control policies in the brain-computer interface developed with active and reinforcement learning techniques in order to perform efficient user intent inference to improve the entire speed-accuracy trade-off curve for alternative communication.

BEHAVIORAL

BCI-FIT language modeling

Adding vocabulary and location information (called partner and environmental input) to the language models in the brain-computer interface from a user's communication partner.
