The aim of this project is a systematic and critical analysis of the studies exploring different interaction modalities in Brain Computer Interfaces (BCIs) for communication. BCIs measure signals related to specific brain activity and translate them into device control signals. This technology can be used to provide users with locked-in syndrome (e.g. late stage Amyotrophic Lateral Sclerosis, ALS) with an assistive device that does not rely on muscular contraction. Several studies about BCI explored mental tasks and paradigms using visual modality. Considering that in ALS patients the oculomotor control can deteriorate and also the potential users with other diseases could have impaired visual function, in the last years, tactile and auditory modality have been investigated to find alternative BCI independent of vision. The aim of this review is to survey the cognitive and neural basis of the tasks explored to control the auditory BCI systems to better understand their limits and potentials applications, toward a real user centered approach helping the scientific community to move the BCIs from the laboratory to user's houses. © 2011 IADIS.

Abstract
The aim of this project is a systematic and critical analysis of the studies exploring different interaction modalities in Brain Computer Interfaces (BCIs) for communication. BCIs measure signals related to specific brain activity and translate them into device control signals. This technology can be used to provide users with locked-in syndrome (e.g. late stage Amyotrophic Lateral Sclerosis, ALS) with an assistive device that does not rely on muscular contraction. Several studies about BCI explored mental tasks and paradigms using visual modality. Considering that in ALS patients the oculomotor control can deteriorate and also the potential users with other diseases could have impaired visual function, in the last years, tactile and auditory modality have been investigated to find alternative BCI independent of vision. The aim of this review is to survey the cognitive and neural basis of the tasks explored to control the auditory BCI systems to better understand their limits and potentials applications, toward a real user centered approach helping the scientific community to move the BCIs from the laboratory to user's houses. © 2011 IADIS.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
