Hi, My name is Chang Liu 刘畅.

I am currently working as research assistant in Pervasive human computer Interaction Lab in Tsinghua University. I have earned a M.Eng. degree in Computer Science from Tsinghua University in July 2024.

My research interest focuses on understanding and leveraging the mutual influence between interaction contexts and user behavior. Specifically, user behavior in a given interaction context can implicitly reflect user’s intentions, strategies, preferences. Conversely, adjustments to the interaction context can potentially impact user behavior. I believe an ideal interaction system should learn from users' daily behaviors and dynamically update itself to enhance the interaction experience.

​

Specifically, I’m interested in pursuing research in the following areas:

1. Exploring the impact of AI as an interaction context. Investigating how AI feedback influences users' behavioral and cognitive patterns.

2. Developing sensing or interactive systems capable of sensing users' long-term physiological changes, such as myopia and muscle fatigue, or psychological changes, such as overstress or depression.

3. Developing efficient multimodal interaction Systems, particularly about eye tracking, human-AI collaboration, or embodied intelligence.
