The driver’s whole-body posture at the time of a collision is a key factor in determining the magnitude of injury to the driver. However, current researchs on driver posture models only consider the upper body posture of the driver, and the lower body area which is not perceived by sensors is not studied. This paper investigates the driver’s posture and establishes a 3D posture model of the driver’s whole body through the application of machine vision algorithms and regression model statistics. This study proposes an improved Kinect-OpenPose algorithm for identifying the 3D spatial coordinates of nine keypoints of the driver’s upper body. The posture prediction regression model of four keypoints of the lower body is established by conducting volunteer posture acquisition experiments on the developed simulated driving seat and analyzing the volunteer posture data through using the principal components of the upper body keypoints and the seat parameters. The experiments proved that the error of the regression model in this paper is minor than that of current studies, and the accuracy of the keypoint location and the keypoint connection length of the established driver whole body posture model is high, which provides implications for future studies.

The nature of the interrelationship between whole body posture and the quality of the dental occlusion has not yet to date been clearly documented within the dental or posture literature, as the findings of published studies within both fields have been scarce and inconclusive. The combined use of digital diagnostic occlusal and postural assessment technologies has not been widely employed in these research projects, which has mired both fields' ability to study, to understand, and to clearly ascertain how posture and dental occlusion affect each other physiologically. As such, the specific aims of this chapter are to outline how posture and dental occlusion interrelate through the stomatognathic system's afferent neural inputs into the central nervous system (CNS), which communicate important occlusal contact force distribution information, and equally as important, mandibular spatial positional information within the posture and balance regions of the brain. The concept that the dental occlusion is a capteur for posture (which in English means, a sensor of posture health), is further explored with the inclusion of three differing clinical posturo-occlusal cases, diagnosed and treated with the combined use of the T-Scan 9 computerized occlusal analysis technology, the MatScan/MobileMat foot pressure mapping technology, and the Footmat Research software version 7.10. These presented clinical cases illustrate that improved right-to-left occlusal contact force balance, and improved center of force location within the dental arches, improve a number of measurable sway parameters. Together, the implementation of the T-Scan and the MatScan exquisitely demonstrate to the clinician the significance of the physiologic interrelationship between body posture and the dental occlusion. The presented cases emphasize there exists a whole-body concept that depends upon a variety of differing systems, whereby changes in the dental occlusion produce a phenomenon of bio-functional neuro-reprogramming for the stomatognathic system and the whole body.

Inverted Face

Researchers have sought to understand the specialized processing of faces and bodies in isolation, but recently they have considered how face and body information interact within the context of the whole body. Although studies suggest that face and body information can be integrated, it remains an open question whether this integration is obligatory and whether contributions of face and body information are symmetrical. In a selective attention task with whole-body stimuli, we focused attention on either the face or body and tested whether variation in the irrelevant part could be ignored. We manipulated orientation to determine the extent to which inversion disrupted obligatory face and body processing. Obligatory processing was evidenced as performance changes in discrimination that depended on stimulus orientation when the irrelevant region varied. For upright but not inverted face discrimination, participants could not ignore body posture variation, even when it was not diagnostic to the task. However, participants could ignore face variation for upright body posture discrimination but not for inverted posture discrimination. The extent to which face and body information necessarily influence each other in whole-body contexts appears to depend on both domain-general attentional and face- or body-specific holistic processing mechanisms.
