Conditions of extreme neurological disability prevent any form of communication, even to show the emotional state. Brain Computer Interfaces (BCI) often use Electro-encephalography (EEG) measurements of the voluntary brain activity for driving a communication system. A BCI usage requires the activation of mental tasks. In the last few years, a new paradigm of activation has been used consisting in the autonomous brain activation through self-induced emotions, remembered on autobiographical basis. In the present paper, we describe the state of the art of an affective BCI system, a-BCI, based on self-induced emotions. It can be used by people with Severe Neurological Disorders (SND) for: alternative communication, emotion transmission.
