Language Model Applications to Spelling with Brain-Computer Interfaces

Language Model Applications to Spelling with Brain-Computer Interfaces

Within the Ambient Assisted Living (AAL) community, Brain-Computer Interfaces (BCIs) have raised great hopes as they provide alternative communication means for persons with disabilities bypassing the need for speech and other motor activities. Although significant advancements have been realized in the last decade, applications of language models (e.g., word prediction, completion) have only r...

An auditory oddball (P300) spelling system for brain-computer interfaces.

This study was designed to develop and test an auditory event-related potential (ERP) based spelling system for a brain-computer interface (BCI) and to compare user's performance between the auditory and visual modality. The spelling system, where letters in a matrix were coded with acoustically presented numbers, was tested on a group of healthy volunteers. The results were compared with a vis...

Brain Computer Interfaces for Medical Applications

Developing neuroprostheses and advanced communication systems for patients with disabilities has involved considerable scientific and technological efforts. Many recent projects developed software and hardware based on BCIs for such patients. Principles of Brain Computer Interfaces (BCI), technologies used for this type of interfaces and the latest research activities in the field of BCIs are p...

Metabolic Brain-Computer Interfaces

Multimodal Brain-Computer Interfaces

A critical parameter of brain-computer interfaces (BCIs) is the number of dimensions a user can control independently. One way to increment this number without increasing the mental effort required to operate the system is to stimulate several sensory modalities simultaneously, and to distinguish brain activity patterns when the user focuses attention to different elements of this multisensory ...
