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.

• High Speed Camera

Just attach the reflective markers to the subjects! You can check the system status and the subjects' movements during measurement.

Using the "MAC3D System," three-dimensional data of walking movements is obtained on a walking path equipped with a floor reaction force measurement device. By using analysis software on the acquired data, inverse kinematics and inverse dynamics analyses can be performed, allowing for the calculation of difficult-to-measure data such as center of mass position and joint torque. The analysis results can be displayed in graphs within the analysis software and can also be output as Excel data. 【Features】 ■ Acquired data: Marker three-dimensional positions, floor reaction forces, electromyography, trigger signals, AVI video ■ Marker set: Helen Hayes, etc. ■ Mass model: Zatsiorsky, custom ■ Skeleton engine: Skeleton Builder, Calcium, hybrid model ■ Analysis methods: Inverse kinematics analysis, inverse dynamics analysis *For more details, please refer to the related links or feel free to contact us.

• Image analysis software

Calculate difficult-to-measure data such as center of gravity position and joint torque! The analysis results are displayed in graphs within the software.

The "MAC3D System," an optical reflective motion capture system, is an ideal solution for three-dimensional measurement (data collection) of body movements. It excels in real-time capabilities, allowing for immediate verification of the system's status and the subject's movements during measurement, enabling quick assessment of whether the desired data has been obtained. Data analysis can be performed using dedicated software, allowing for inverse kinematics and inverse dynamics analysis to evaluate the stability and maturity of movements, and appropriate prescriptions can be made for each individual based on the results. 【Features】 ■ Acquisition of three-dimensional data of walking movements ■ Subjects only need to have reflective markers attached ■ Capable of calculating difficult-to-measure data such as center of gravity position and joint torque ■ Analysis results: displayed in graphs within the analysis software and output as Excel data ■ Immediate assessment of whether the desired data has been obtained *For more details, please refer to the related links or feel free to contact us.

• Image analysis software

No markers needed, no special suit required, no post-processing necessary for body measurement! Simple preparation and operation allow for immediate measurement.

Theia3D is a markerless motion capture system developed for biomechanics research. It extracts the human body from video data captured by more than six cameras and automatically generates skeletal model data using rigid body tracking and inverse kinematics. There is no need for markers or specialized suits that were essential in traditional motion capture systems. You can wear regular clothing, and preparation time is minimal. Additionally, no specialized knowledge is required to operate the software, allowing anyone to easily perform human measurements. 【Features】 ■ Analyzable from video data captured by synchronized cameras (more than six). No specialized cameras required. ■ Supports analysis of only the upper body or lower body. ■ No limit on the number of people that can be analyzed. ■ Supports motion analysis software Visual3D. ■ Batch data processing functionality available.

About ROAD: The "Roundtable on the Purpose of Autonomous Driving (ROAD)" conference series has evolved into a unique platform for interdis-ciplinary dialogue and international collaboration in the field of autonomous driving and autonomous mobility. Established in 2016, ROAD has brought together researchers, industry leaders, and public sector stakeholders from six countries across three continents. Based on this background, the upcoming ROAD 2026 will focus on "safety” and "driving AI”—the final pieces of the autonomous driving puzzle—to advance discussions on establishing the foundational framework for ensuring safety quality and obtaining regular-tory approval for autonomous driving. We also intend to discuss the international commonalities and differences regarding the social value brought about by ADS vehicles in terms of automation, intelligent driving, and mobility. We have established a total of five compelling themes for the Round Workshops, consisting of two topics related to “The Last Piece” and three topics related to the social value of ADS, as shown below. 1) Round Workshop 1 - Horizons of E2E Driving AI → Can AI Understand the Driving Environment Like Humans? 2) Round Workshop 2 - Beyond the Unknown: Safety Cases for ADS → Can Safety Ever Be Proven? 3) Round Workshop 3 - Envisioning Smart City Mobility → Can Smart City Mobility Bridge the Mobility Divide? 4) Round Workshop 4 - Logistics Enhancement Through Autonomous Tracking → Will Logistics Become Human-Free? 5) Round Workshop 5 - The Evolution of CASE: SDV/AIDV → Will Automakers Become AI Companies? We hope you’ll all join us!

[Speaker] Masashi Sugita, President and CEO of LEX Style Co., Ltd. [Key Lecture Content] The power consumption of AI servers used in data centers has significantly increased, making traditional air cooling insufficient for operation. This lecture will organize the requirements for introducing a liquid cooling system into air-cooled data centers and explain the implementation method using free cooling with specific design details. When handling high-density AI servers, energy efficiency is required, and the widely used energy efficiency indicator, as well as the Ministry of Economy, Trade and Industry's Resource and Energy Agency's PUE regulation of "1.3 or below," will be explained along with practical operational insights.

[Instructor] Yuichiro Kabushiki, Partner Lawyer at TMI Comprehensive Law Office [Key Lecture Content] With the spread of AI, there is growing attention on the civil liability of developers, providers, and users of AI. The Ministry of Economy, Trade and Industry will publish "Guidelines on the Interpretation and Application of Civil Liability in AI Utilization" in April 2026, and the Ministry of Justice will also establish an expert meeting to examine civil liability related to unauthorized use of images and voices generated by AI in the same month. As the full enforcement of the AI Promotion Act and the revision of AI guidelines are underway, it is necessary to design and operate governance based on the potential responsibilities that may arise retrospectively. In this seminar, based on the guidelines from the Ministry of Economy, Trade and Industry and drawing on litigation practice experience as a judge and lawyer, we will organize the basic framework for assessing civil liability and explain fundamental methods for designing and operating governance based on risk analysis. Furthermore, we will examine the framework for civil liability and the design and operation of governance using hypothetical cases that are likely to pose practical issues.

In this seminar, we will welcome Mr. Satoru Hayami from Waseda University, who will explain the latest trends in AI utilization in manufacturing, as well as the evolution of technologies such as agent-based AI and physical AI, and the opportunities and key points for practical application in the manufacturing industry. Furthermore, Mr. Tsubasa Shibata, representative of Next Opt, will introduce processes aimed at practical implementation, incorporating actual case studies from manufacturing sites. We hope you will envision the "potential for AI utilization in your company" and take home hints that will lead to improvements in your operations starting tomorrow. We look forward to your participation.
