Neural Control Interfaces

Abstract

The control interface is the primary component of a Brain-Computer Interface (BCI) system that provides user interaction. The control interface supplies cues for performing mental tasks, reports system status and task feedback, and often displays representations of the user's brain signals. Control interfaces play a significant role in determining the usability of a BCI, and some of the traditional human-computer interaction design methods apply. However, the very specialized input methods and display paradigms of a BCI require consideration to create optimal usability for a BC! system. This chapter outlines some of the issues and challenges that make designing control interfaces for BCIs unique.
