According to the Guided Activity Principle, students perform better in learning tasks when a pedagogical guide is present in a learning platform.

"Ani-mated pedagogical agents play instructional roles to support sociocognitive aspects of multimedia learning; can follow social conventions; and provide empathetic responses to learners (Hayes-Roth & Doyle, 1998). These agents are represented visually, often with human features, and with optional auditory (speech) features."

This phenomena calls for emotionally intelligent human-computer interactions. A virtual guide could adjust their approach and emotional expressions after noticing emotional fluctuations in the user.

While this sounds like a technical challenge in the field of human-computer interaction, a short-cut method could be applied, in which a team of researchers and designers "predict" emotional changes in the user in certain sections of a platform, and install a virtual guide that help the user learn content more effectively.
