The Research of Emotional State Influence on Quality of a Brain-Computer Interface Usage

Nowadays due to the brain-computer interfaces it becomes possible to make a reasonable assumption about the cognitive activity of the user and to recognize certain mental commands, which is used for various purposes, including robotic devices control. In addition, modern brain-computer interfaces allow to monitor affective activity that contributes to real-time monitoring of the operator' emotions. In this paper the influence of affective activity on the quality of recognition of the cognitive commands is considered. For this purpose, methods of excitation of a certain emotional state are used. The result of the research is a methodology of improving the quality of recognition of mental commands by taking into account the emotional state of an operator during the command execution.
