Scientific Reports, 16(1), Apr 2, 2026 Peer-reviewedCorresponding authorAbstract In the practice of medicine, tracheal intubation is a critical procedure, yet medical education often lacks quantitative instructional methods, relying instead on intuitive guidance from experts. This study used motion capture and eye tracking to analyze differences in movement and gaze between novices and experts during tracheal intubation. It also compared the use of direct and video laryngoscopes. Results showed that with a direct laryngoscope, experts directed their gaze farther than novices during the laryngoscope insertion phase, with a significant difference in eye-to-gaze distance [experts: 0.465 m; novices: 0.325 m; t (12) = 2.690, p = 0.020]. No significant difference was found when a video laryngoscope was used, suggesting that novices could perform expert gaze behavior. Head movement analysis revealed that experts maintained a greater distance from the mannequin’s mouth when using direct laryngoscopes (experts: 0.529 m; novices: 0.331 m). With video laryngoscopes, the gap narrowed (experts: 0.550 m; novices: 0.457 m). A t-test comparing novice head-to-mouth distance between device types showed a significant difference [t (14) = 4.355, p = 0.001]. These findings highlight how video laryngoscopes may help novices approximate expert behavior, offering potential for improved training methods.

The Proceedings of the Dynamics & Design Conference, 2019 505, 2019A mobility system named TSMD has been proposed as new moving means under microgravity such as outer space. By winding tether that was extension, TSMD cause to move human. In this system that extend and wind tether under microgravity such as TSMD, contact force between the tether and the rigid body is expected to influence the motion of the system. Therefore, in this paper, the influence of contact force between a flexible body (tether) and slit that has elastic wall (outlet and inlet of tether) that gives the motion of the system is analyzed. The analytical model of the TSMD that moves in a two-dimensional plane was made and was simulated by changing the slit shape using this model. As a result, it was confirmed that the attitude control method focusing on rotational energy was effective under all conditions in which the shape of the slit at inlet was changed. In addition, it was confirmed that the shape of the slit affects the responsiveness of the control effect. Moreover, it was found that there are suitable slit shape that improves the responsiveness of the control effect.

The Proceedings of the Symposium on sports and human dynamics, 2019 B-14, 2019The purpose of this paper is to build a selection index for tennis rackets. By investigating the effect of the racket on its stroke motion, derived motion indices were used to evaluate the tennis racket. During its swing, the feature points of the motion are derived by calculating the contribution of each part of the body in the tennis stroke motion, and the analysis is performed focusing on the feature points. The subjects of the study were three male senior tennis players and two male beginner players. Stroke motion and the three-dimensional information of each part of the human body was recorded with twelve motion capture cameras and six rackets with different characteristics. By using three-dimensional information, characteristic markers of the tennis strokes were derived. The vertical position of the marker was analyzed, and the change in the stroke motion of each racket was examined. Focusing on the swing variation from racket to racket, the sum of standard deviations was used. The analysis was performed by comparing the sum of standard deviation and swing speed. As a result, the relationship between the sum of the standard deviation and the swing speed for the stroke motion was shown.
