Projects
Real-time Sound Synthesis of Rigidbody Objects
The main contributions of this work are to utilize the mass-spring-damping system to obtain vibrations on collision events and provide an interface for sound simulation in the current mainstream game engine - Unity.
The innovative parts of this project mainly focus on the accelerating techniques for the real-time sound that could also be used for large scenes with even hundreds of objects producing sounds.
Folding Clothes
Fold clothes arbitrarily in virtual environments or fold clothes according to the coordinates input.
Seat Plus: A Smart Chair for the Good Sitting Posture
Real-time analysis of human being’s sitting postures was performed based on a delicate user study. GUI interactive design & animation are involved.
Interactive Design for Simulated Windshield Displays in Cars
Interaction design & UI animation based on trackpads of Vive Pro Controllers in virtual simulated driving scenarios
