From correcting exercise movements to rehabilitation treatment by wearing or attaching clothes
Customized maps and remote guidance will improve educational efficiency.

ETRI developed a technology that can analyze and compare the movements of the subject and myself in 3D by attaching 17 sensors and 10 actuators to the major joints of the human body, and provide a vibration signal to correct any incorrect movements.

The research team explained that this technology can determine joint angles and three-dimensional position coordinates using data obtained from sensors installed at each of the 17 joints. Wearing the device or attaching a band can help with everything from correcting spinal posture during exercise to rehabilitation therapy.


The newly developed technology includes ▲a suit for preventing spinal disease, ▲a suit for learning golf motions, and ▲interactive real-time golf learning content. For example, when learning golf or baseball, after receiving instruction from an instructor, you can watch a video comparing your swing to that of a famous player. Detailed data, such as elbow angle and head position, are displayed on the screen, calculating and compensating for any discrepancies between the player's movements and your own.

The top is equipped with sensors and actuators, while the bottom is equipped with detachable band-type sensors attached to the thighs, calves, and ankles. Specifically, when movements deviate from the calculated values during exercise, a vibrational "drumming" sound is felt, allowing for focused learning. Furthermore, if a specific area is problematic, the sensor device can be installed specifically to that area for strengthening training. This reduces learning time by incorporating existing data and allows for personalized training, increasing efficiency. Distance learning is also possible.

The research team predicts that it will be widely used in future leisure sports and physical activity posture training, rehabilitation treatment education programs, and content businesses.
This achievement was led by ETRI, with the joint participation of Korea Textile Research Institute, Korea Jacquard Textile Research Institute, Sangmyung University, Chosun University, KAIST, and Vienes Soft.
