Tutoring System

Emotion is one of the key elements involved in learning and education; it affects our decision making, our communication and our ability to learn. Therefore in this project we proposed the use of an electroencephalography (EEG) device called the Emotiv EPOC to detect a user’s emotions via brainwaves in an Intelligent Tutoring System (ITS). We aimed to test the accuracy and applicability of this device in an ITS called EER-Tutor. First we aimed to test the EPOC’s accuracy in detecting emotions by comparing EPOC’s emotional values with participants ’ self-reported scores. Emotions were induced using the International Affective Picture System (IAPS). Due to a lack of reliable data this study was then improved upon and re-conducted. The improved study still resulted in no significant findings as a relationship between self-report scores and EPOC emotional values could not be found. Therefore a different approach was adopted to test the accuracy and applicability of the EPOC. In our third study we tested the EPOC in EER-Tutor using a think-aloud protocol. The utterances of participants were compared to the emotional values EPOC produced. These utterances were defined by context of statement, action taken and timing and placed into categories. N
