Components of the BCI prototype developed within the project Backhome. Caregivers and/or researchers are guided through the process necessary to start the BCI in a stepwise procedure with a graphical user interface (A). The user is seated in front of the screens used to display the applications (B) and control matrices (D). The EEG Hardware (C) consists of the g.Nautilus system that is either equipped with dry contact (depicted) or gel-based electrodes. The control matrices (D) contain a fixed number of elements except for the web browser, for which the number of elements is determined dynamically depending on the number of hyperlinks on the web page. For all other applications, the number of elements in the matrix depend on their functionality (e.g., the speller matrix contains more elements than the control matrix for the media player).
