My core research is in the area of interest-based learning, an approach to instruction that leverages students’ interests (like music, soccer, cooking, etc.) to build relevance with learning content. I look at how large language models can be used to automate the generation of interest-based content, which is often challenging to scale manually.

I’m investigating how does the incorporation of virtual agents in immersive virtual reality can improve people’s mental well being. The virtual agents can vary by role (e.g., guider, motivator, companion), appearance (gender, age, similarity), and visual representation (audio only agent, humanoid, pets). The manipulation and combination of virtual agents in the virtual space can help or hinder user experiences and mindfulness states in different aspects.

Heting Wang<\/h4>\n\n\n\n

My research centers around differentiating frustration from cognitive workload using brain activation. Cognitive workload is introduced in tasks within a user’s everyday life, and different people exhibit different levels of activation and\/or behaviors even when the workload remains consistent, due to emotions like frustration. This prompts the design of a user-centered classifier that is able to “tease out” frustration from cognitive workload. Potential applications can be used for human-AI collaboration in improving educational outcomes.
