Abstract

 Brain-computer interfaces  Electrophysiological sources of control in BCI  Emotions  EEG correlates of emotion  Emotions and BCI operation  Emotive BCI operation  Research agenda 2 2 3 BRAIN COMPUTER INTERFACE (BCI) Brain activity Monitoring Mental activity (MA) Translation into commands Application Feedback Brain signals Commands Cursor movement Wheelchair A BCI detects the presence of specific patterns in a person's ongoing brainactivity that relates to the person's intention to initiate control. The BCI translates these patterns into meaningful commands

Classification of Human Emotions from Electroencephalogram (EEG) Signal using Deep Neural Network

“…Emotions can be generally classified on the basis of two models: discrete and dimensional [2], [5]. Dimensional model of emotion proposes that emotional states can be accurately represented by a small number of underlying affective dimensions.…”

“…Instruments that measure blood pressure responses, skin responses, pupillary responses, brain waves, and heart responses are all used as objective measures methods. Moreover, hybrid methods combining both subjective and objective methods have been used to increase accuracy and reliability of affective emotional states [2], [6].…”

“…with games, adjusting to the interest of the user) [1]. Recognizing a user's affective state can be used to optimize training and enhancement of the BCI operations [2].…”

Artistic brain-computer interfaces: state-of-the-art control mechanisms

“…This study can help shape future research into artistic BCIs for therapy purposes, helping patients work through anger or fear by teaching them to focus on relaxing their emotional state in order to create different types of art. Researchers can look to [25] for more information on emotional BCIs.…”

“…When users are in a relaxed state, their alpha waves (7-13 Hz) are transmitted and the steel sky is silent, other than one 'ding' every four seconds. When users are focused, beta rhythms (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) are present and the steel sky lights up with cacophonous sounds of banging steel. The musical feedback prompts the user to either continue in their same mental state, or to attempt to change their current brainwave frequencies, depending on personal preference.…”
