Such an hBCI allows the processing of several input signals with at least one brain signal for control purposes, i.e. communication and environmental control. This work shows the principle, technology and application of hBCIs and discusses future objectives.Hybrid BCIElectroencephalogram (EEG)Assistive technologytext::conference output::conference proceedings::conference paper
