World Gymnastics and Fujitsu have been collaborating since 2017 to develop the Judging Support System (JSS), an AI-powered technology designed to support the evaluation of artistic gymnastics performances.
JSS assists judges by using advanced AI and motion analysis to recognize gymnastic elements, provide multi-angle video review, and deliver objective numerical information on gymnasts’ movements. By supporting judges with advanced technology, JSS contributes to greater fairness, consistency, and transparency in the sport while preserving the role of human judgment in all official decisions.
Supporting objective evaluation for all athletes based on the same standards.
Providing visual and numerical evidence to assist decision-making.
Helping judges apply the Code of Points in the same way worldwide.
Artistic gymnastics continues to evolve, with athletes performing increasingly complex and dynamic skills. As difficulty levels rise, judges must evaluate routines accurately and consistently within a very short period of time.
World Gymnastics is committed to safeguarding the integrity of the sport and ensuring that all athletes are evaluated according to the same standards. JSS was developed to support this goal by providing judges with additional objective information when assessing performances.
JSS is a judging support tool. It does not replace judges and does not make official judging decisions.
Instead, JSS provides additional information to assist judges in applying the Code of Points consistently and accurately.
JSS enables judges to observe performances from any angle, providing additional perspectives on body positions and element execution. This empowers judges with valuable insights to support fair and consistent evaluations.
The system provides objective numerical information on gymnasts’ movements, such as body positions and angles, supporting judges when evaluating technically demanding elements.
By providing relevant information quickly during competition, JSS helps judges review performances efficiently while maintaining consistency.
JSS plays an important role beyond competition operations by supporting the development of Element Recognition Criteria, judge education, Technical Committee activities, and data-based support for National Federations.
The data and analysis generated through JSS support the development and refinement of Element Recognition Criteria, helping to establish greater clarity and consistency in judging standards.

JSS supports educational activities by providing visual and numerical examples that help judges better understand technical requirements and evaluation standards.
World Gymnastics is expanding opportunities for National Federations to benefit from JSS-generated data and insights to support athlete and coach development.
JSS supports the future development of sport presentation by providing visual and analytical content that can help audiences better understand gymnastic performances. Through broadcast, digital, and event-based experiences, JSS has the potential to make the sport more accessible and engaging for fans around the world.
Since its first official use in 2019, the Judging Support System has expanded across more apparatuses and competition settings (see Element Recognition Criteria for more details).
