The “AI Badminton Coach” that shined at CES was the brainchild of AssistantProfessor Tsong-sheng Zheng from the Department of Electronic Engineering,STUST, led by graduate studentsJia-shuan Lu and You-lin Yeh, and developed incollaborationwith ITRI’s Optoelectronics Research Institute. This intelligent trainingsolution integrates two core technologies: “2D-to-3D Motion Posture Determination”and “Motion Analysis and Response” based on a Retrieval-Augmented Generation(RAG) architecture. It also incorporates ITRI’s advanced 3D packaging technology toprovide an innovative, high-performance coaching experience.

Theirsuccess is a testament to STUST’s achievements in AI R&D and collaborativeinnovation, and represents a shining example of Taiwan’s technological prowess onthe global stage.】

The “AI Badminton Coach” system employs high-speed camera sensors to capturedetailed motion and posture data, such as swing trajectory and point-of-contactprecision—in real time. This data is transmitted to a cloud platform, where powerfulgenerative AI algorithms analyze athletic performance with up to 99% accuracy. Thesystem then delivers personalized training plans tailored to each user’s needs. Thisinnovation not only boosts performance for recreational players but also providesefficient, data-driven training support for professional athletes.

日Recently, representatives from ITRI’s Optoelectronics Laboratory visited STUST tocelebrate this international achievement with the Department of ElectronicEngineering’s research team. Their long-standing collaboration has not only producedremarkable technological results but also exemplifies the strength of Taiwan’sindustry-academic partnerships and the ability of Taiwan technology to compete onthe world stage.

Looking ahead, Assistant Professor Tsong-sheng Zheng shared the team’s vision toexpand the system’s applications into smart healthcare and intelligent manufacturingsafety. He explained that posture analysis is a crucial diagnostic indicator in medicalprocesses. Withadvanced 3D posture analysis, early-stage disease detection canbecome moreaccurate,overcoming the limitations of traditional 2D systems affectedby camera angles. Whenintegrated with a large language model (LLM) powered bythe RAG framework, the system can offer instant voice-based feedback and expert- level guidance.

President Nen-fu Huang of STUST emphasized the university’s long-terminvestment in AI research. STUST has established several R&D centers focused onsmart healthcare, smart manufacturing, sports technology, and intelligent energysystems. The campus provides state-of-the-art facilities, an excellent learningenvironment, and a team of professional faculty members. It has also earnedrecognition and support from major tech leaders, including Jensen Huang, Founder ofNVIDIA. The success of the “AI Badminton Coach” at CES 2025 is a powerfultestament to STUST’s leadership in AI research and its commitment to fostering high-impact academic-industry collaboration.
