What kind of assistance can BCI actually offer to disabled persons? Despite progress in AT, there is still a large number of people with severe motor disabilities who cannot fully benefit from AT due to their limited access to current assistive products (APs). For them, BCI is the solution. However, notwithstanding the impressive demonstrations of BCI technology around the world, today's state-of-the-art is such that BCI alone cannot make patients interact with and control assistive devices over long periods of time and without expert assistance. But this doesn't mean that there is no place for BCI. The solution is to use BCI as an additional channel. Such a hybrid approach, where conventional APs (operated using some residual muscular functionality) are enhanced by BCI technology, leads to what we call hybrid BCI (hBCI).
