Fédérale de Lausanne (EPFL), Switzerland. He holds a PhD in computational neuroscience from the EPFL (2005). His research focuses on robust brain-machine interfaces and multimodal human-machine interaction. In particular, the study of brain correlates of cognitive processes such as error recognition, learning and decision-making. As well as their use for interacting with complex neuroprosthetic devices. Melanie Fried-Oken, Ph.D. is a clinical translational researcher in Augmentative and

She provides expertise about assistive technology for persons with severe communication impairments who cannot use speech or writing for expression. She is a Professor of Neurology, Pediatrics, Biomedical Engineering and Otolaryngology at the Oregon Health & Science University (OHSU); Director of OHSU Assistive Technology Program, and clinical speech-language pathologist. She received her Ph.D. from Boston University in 1984 in Psycholinguistics; her M.A. from Northwestern University in Speech-Language Pathology, and B.A. from the University of Rochester. She has written over 40 peer-reviewed articles, numerous chapters and given over 200 national and international lectures on AAC for persons with various medical conditions. She has been PI on 16 federal grants and co-investigator on six federal grants to research communication technology, assessment and intervention for persons with developmental disabilities, neurodegenerative diseases, and the normally aging population. Sonja Kleih, Ph.D. received her M.Sc. in Psychology and investigated the effects of motivation on BCI performance. She received her PhD in Neuroscience in 2013 from the University of Tübingen, Germany. Since then she worked as a Post-Doctoral researcher in Prof. Andrea Kübler's BCI lab at the University of Würzburg, Germany. Her research interests are BCI based rehabilitation after stroke, user-centered design and psychological factors influencing BCI performance. Fabien Lotte, Ph.D. obtained a M.Sc., a M.Eng. and a PhD in computer sciences, all from INSA Rennes, France, in Research in brain-computer interfaces has achieved impressive progress towards implementing assistive technologies for restoration or substitution of lost motor capabilities, as well as supporting technologies for able-bodied subjects. Notwithstanding this progress, effective translation of these interfaces from proof-of concept prototypes into reliable applications remains elusive. As a matter of fact, most of the current BCI systems cannot be used independently for long periods of time by their intended end-users. Multiple factors that impair achieving this goal have already been identified. However, it is not clear how do they affect the overall BCI performance or how they should be tackled. This is worsened by the publication bias where only positive results are disseminated, preventing the research community from learning from its errors. This paper is the result of a workshop held at the 6th International BCI meeting in Asilomar. We summarize here the discussion on concrete research avenues and guidelines that may help overcoming common pitfalls and make BCIs become a useful alternative communication device.
