Pedagogical Agents

Stress-sensitive Liza

This stress-sensitive pedagogical agent is based on the conversational agent Liza. The functionality of the previous agent is extended by analysing the mental demand of the user and adapting the learning situation accordingly through execution of coping strategies. The availability of the wristband E4 from Empatica Inc. and a tablet pc with the iOS operating system is essential for full usage.
