On July 22, Virtual Fes 2023‑Hong Kong, Hong Kong’s first‑ever on‑site offline VTuber concert, was successfully held. 

The venue was packed with enthusiastic fans who cheered, screamed and waved glow‑sticks, fully immersed in the vibrant atmosphere of live music and dance performances.

As the exclusive motion‑capture provider for this VTuber concert, CHINGMU delivered full‑range motion‑capture support and brought Hong Kong audiences a spectacular summer audio‑visual feast.

During the live broadcast, CHINGMU deployed its self‑developed, domestically‑built Prometheus lightweight optical motion‑capture system. High‑precision, low‑latency optical cameras installed in the back‑stage capture room precisely tracked and reproduced the dance movements of multiple performers in real‑time, converting them into animation data for virtual idols. Processed by the occlusion‑resistant algorithm built into CHINGMU’s proprietary motion‑capture software, the data drove lifelike singing‑and‑dancing performances of virtual idols displayed live on the LED screen. Even with multiple performers executing highly complex dance moves, the occlusion‑resistant algorithm delivered reliable tracking of subtle limb motions such as hand and foot movements during multi‑person interactions. The ultra‑smooth, stunning live visuals offered the audience strong immersion and interactive engagement.

CHINGMU’s lightweight optical motion‑capture system features high accuracy, real‑time multi‑angle tracking, high flexibility, small footprint and user‑friendly operation. These strengths greatly enhance the realism of virtual‑idol live‑streaming and deliver extraordinary viewing experiences.

As a vital bridge connecting the virtual and physical worlds, virtual‑idol live‑streaming is enjoying robust growth. Beyond entertainment, its applications are expanding into education, business, social interaction and other sectors, bringing brand‑new experiences and value to users. CHINGMU adheres to the mission of serving global clients with sophisticated motion‑capture technology and continuously improved overall capabilities, maintaining strict standards for the realism, real‑time performance, tracking stability and professional service of virtual‑idol outputs.
