The system bases its inferences about students' emotions on user input evidence from the keyboard and the microphone. Evidence form these two modes is combined by a user modelling component underlying the user interface. The user modelling component reasons about users' actions and voice input and makes inferences in relation to their possible emotional states.

The evaluation of the developed system showed significant improvements in the recognition of the emotional states of users.Read More
