An explanation of examples of beginner and experienced Ayatobi using a three-dimensional motion analysis system! It measures the differences and changes in body posture and movement.
The markerless three-dimensional motion analysis system "Anakin System" allows for motion measurement without markers and while wearing everyday clothing, making it possible to measure posture and movements without hassle by bringing the equipment to the site. In the example of the "Ayatori" (string figure), we focus on the lateral opening of the body at the LeftForceArm (wrist) and the height of the LeftFoot (foot) from the floor. Beginners have a decent timing for opening their arms, and although they initially jump higher than advanced users, they gradually drop lower, while advanced users are evaluated to jump lower but more stably compared to beginners. 【Features】 - Allows for precise motion analysis without attaching markers to the subjects. - No specialized knowledge is required for attaching markers due to the markerless design. - Measurements can be taken quickly while wearing everyday clothing. - Measurement results can be immediately checked on a computer and analyzed on-site. *For more details, please refer to the PDF materials or feel free to contact us.

basic information
**Why measure a person's posture and movements?** The ease or difficulty with which a person handles objects manifests in their posture and movements unconsciously. For example, the way to open an easy-to-open container differs from that of a difficult one. Furthermore, the way a person walks varies between comfortable shoes and uncomfortable ones. Additionally, the condition of a person's body is also reflected in their posture and movements. For instance, the way a person walks changes with aging or illness. There are also studies showing that individuals at higher risk for dementia tend to have slower walking speeds. Conversely, those who regularly train their bodies show the effects in their walking posture. **Why can it be measured without markers?** A depth camera captures data on the entire body shape of a person (surface point cloud). However, this data alone does not provide information about joint positions. By overlaying this data with a standard human model of similar height, it is possible to determine joint positions. This is how posture and movements can be understood without markers. *For more details, please refer to the PDF document or feel free to contact us.*
