GCT623/MV623 Spring 2025
Interaction Sensing Principle & Application



This course will educate core principles of 3D & Physical sensing adopted for human-computer interaction. We will cover basic optics for 3D sensing and basic knowledge of each component for physical sensing. Also, we will look at applications where 3D & physical sensing is combined to provide interaction.
