Create a musculoskeletal model from markers! Build a system that can obtain data for muscle strength estimation.
The motion capture system "MAC3D System" can acquire three-dimensional position data of markers attached to the body. Using point data, it estimates body data such as joint positions, joint angles, center of gravity, and muscle strength through musculoskeletal model motion analysis software. There are ongoing efforts by various automobile manufacturers and research institutions to explore whether this body data can be used as one of the indicators for evaluating ride comfort in vehicles. 【Features of MAC3D System】 ■ Capable of acquiring three-dimensional position data of markers attached to the body ■ Estimates body data such as joint positions, joint angles, center of gravity, and muscle strength using musculoskeletal model motion analysis software from point data *For more details, please refer to the related links or feel free to contact us.

basic information
【Case Study】 <Spinal Posture and Ride Comfort> ■ Using the model that estimates spinal posture in the musculoskeletal model motion analysis software "nMotion musculous," the angle of the spine during riding is calculated. ■ The angles from the first cervical vertebra to the seventh cervical vertebra, from the first thoracic vertebra to the twelfth thoracic vertebra, and from the first lumbar vertebra to the fifth lumbar vertebra are calculated. ■ Data comparisons and analyses are conducted for each seat. <Muscle Strength and Ride Comfort> ■ A system capable of obtaining data for muscle strength estimation has been established. ■ The floor reaction force gauge is embedded in the seat, and the position of the floor reaction force gauge is estimated using the MAC3D System to calculate the contact force. ■ The design also considers a moving floor reaction force gauge, allowing for accurate measurements. *For more details, please refer to the related links or feel free to contact us.
