Adding sensor-free intention-based affective support to an Intelligent Tutoring System
作者：
Highlights：
• A sensor-free affect-aware Intelligent Tutoring System (ITS) is presented.
• The ITS is able to adapt feedback to positively affect pleasure, arousal or dominance.
• The system does not use a specific emotion detection system during operation.
• Results show that the level of scaffolding influences the subject’s affective state.
• An experiment in a real educational setting led to statistically significant results.
