Research approach – The work presented is part of a European funded project incorporating a range of academic and industrial partners, each bringing a skill and expertise in the main components of a BCI system, namely, signal acquisition, signal processing and application. The focus of the project has been to develop the BCI in a user centred design approach involving typical end users throughout the design and evaluation process.
Findings/Design – The project is multifaceted bringing with it a range of challenges from the mathematical algorithms through to the user experience. Each aspect will have a knock-on effect to the end user and how they will be able to operate the system. This paper highlights the issues that need to be considered to develop a user interface for such a multipurpose system.
Research limitations/Implications – Only the first of the three BCI paradigms has been used in this project so far.
Originality/Value – The research is novel in that is focuses on the user needs and human interface requirements in BCI research.
Take away message – Brain computer interfaces can offer a mechanism for communication and environmental control for highly disabled people. However, as a usable technology in real environments it is still in its infancy. This paper will present and discuss the challenges that are met when developing a BCI system for use in domestic setting with disabled users.
