Introduction to Brain-Computer Interfacing Using Bci2000 (Human-Computer Interaction)by Gerwin Schalk
Synopses & Reviews
Brain-Computer interfaces (BCIs) use brain signals to communicate a usera (TM)s intent. Thse systems do not depend on peripheral nerves and muscles. Thus, they can be used by people with severe motor disabilities to express their wishes to the outside world just by thinking. Many laboratories have begun to develop BCI systems to provide communication and control capabilities to people with severe motor disabilities. Further progress and realization of practical applications depends on systemic evaluations and comparisons of different brain signals, recording methods, processing algorithms, output formats, and operating protocols. However, the typical BCI system is designed specifically for one particular BCI method and/or does not facilitate comprehensive BCI research programs, and is therefore not suited to the systematic studies that are essential for continued progress.
In response to this problem, since 2000 we have been developing a documented general-purpose research and development platform, called BCI2000. BCI2000 can be used for BCI research, but also for a variety of other data acquisition, stimulus presentation, and brain monitoring applications. The mission of the BCI2000 project is to facilitate research and applications in these areas. Our vision is that BCI2000 will become a widely used software tool for diverse areas of real-time biosignal processing. The BCI2000 system is available for free non-profit research and educational purposes at http: //www.nci2000.org . It has been acquired by more than 140 laboratories around the world.
This book provides an overview of relevant areas of BCI research. It also gives a detailed description of the use of the system for the investigator, end user, and software engineer.
Using the BCI2000 software platform, this volume provides an introduction to Brain-Computer Interface (BCI) experiments. Basic BCI operating principles are described, in addition to signal processing, and a variety of brain signal acquisition methods.
This practical guide to successful Brain-Computer Interface (BCI) experiments, uses the general-purpose software platform BCI2000. It provides comprehensive introductory and intermediate concepts of all relevant aspects pertaining to common BCI experiments. Opening with a general introduction to the principles of BCI operation, brain signal acquisition using different types of sensors, BCI signal processing (including common feature extraction and feature translation methods), and device output, this general introduction to BCI research is followed by an introduction to the BCI2000 software platform, including a step-by step tour and step-by-step tutorials for using BCI2000 with sensorimotor rhythms and P300 evoked potentials. Advanced concepts are discussed and a programming reference and exercises included. There is a section for frequently asked questions and technical references. Graduate students and postdoctoral associates getting started with BCI research and/or the use of BCI2000 will find this book very valuable. The tutorials and exercises will also prove useful for further reading and for lab assignments in courses on BCI research.
