WS4 - BCIs for training and assessment in neurorehabilitation

Brain-computer interfaces (BCIs) can be realized with EEG, ECoG, or spike activity recorded from the brain. A BCI translates brain waves into signals which can be interpreted by computers either to make statements about the brain itself, or to control an attached output device. BCIs have been developed during the last years mainly for people with severe disabilities to improve their quality of life. The integration of BCIs into rehabilitation settings is a promising new approach that enhances the whole rehabilitation process.
g.tec developed therefore the g.RehaBCI that detects activations of the motor cortex and controls several feedback devices like rehabilitation robots or Virtual Reality environments. During the first part of the workshop we will present an introduction into the field of BCIs and show several approaches to EEG-based BCIs, as well as give insight into research that uses invasive electrophysiological data acquisition methods. In the second part we will focus especially onto BCIs for neurorehabilitation. The g.RehaBCI will be presented and also used in hands-on sessions.


Guger Technologies OG was founded in 1999 in Graz. The company develops hardware and software for biosignal acquisition and analysis. Currently, g.tec is selling biomedical equipment in more than 60 different countries and is the main worldwide supplier of brain computer interface technology. The g.tec company has received several awards in Austria, such as 2006 GEWINN Award, the best start-up company out of 1500 companies in 2006, 2008 Fast Forward Award, 2009 Econovius Award, 2011 Pegasus Award; and in Europe, 2007 European ICT price, 2007 Well-Tech Award, 2010 Microsoft Innovation Award, sponsor of the BCI research Award.


The Workshop attendees will learn and carry out all the steps that are necessary to perform BCI experiments on their own. They will receive a broad overview over the physiological processes in the brain and the tricks of the trade for data processing. Furthermore, they will learn the basics about EEG recordings, how to assure to get high data quality and how to clean the data from artifacts. They will get insight into detecting activation of motor regions and how to apply online feedback to the user.


M.Sc. Arnau Espinosa, software developer and researcher of Guger Technologies OG (g.tec). He is working on EEG, ECoG and spike based BCI projects within g.tec. He is involved in EC projects like Back Home, Vere, Renachip, ALIAS, Brainable, Decoder and Better and will also talk about these projects.
