Compensation of Magnetic Disturbances Improves Inertial and Magnetic Sensing of Human Body Segment Orientation

A tool that predicts the trajectories of linked human body segments on the basis of their inertial properties could be useful in the analysis of fall accidents. In order to be of value in forensic applications, relevant attributes of both the plaintiff and accident site must be modeled at some requisite level of fidelity. By systematically varying different attributes of the model, e.g., avatar posture, body segment velocity, coefficient-of-friction between modeled treads and footwear, it is possible to examine the likely consequences on body-segment trajectories. Trajectories and collisions can then be compared with patterns of injury, plaintiff testimony, and witness accounts.

Segment Orientation

We present a real-time human body-segment (e.g., upper limbs) orientation estimation scheme in rider-bicycle interactions. The estimation scheme is built on the fusion of measurements of an un-calibrated monocular camera on the bicycle and a set of small wearable gyroscopes attached to rider’s upper limbs. The known optical features are conveniently collocated with the gyroscopes. The design of an extended Kalman filter (EKF) to fuse the vision/inertial measurements compensates for the drifting errors by directly integrating gyroscope measurements. The characteristic and constraints from human anatomy and the rider-bicycle interactions are used to enhance the EKF performance. We demonstrate the effectiveness of the estimation design through bicycle riding experiments. The attractive properties of the proposed pose estimation in human-machine interactions include low-cost, high-accuracy, and wearable configurations for outdoor personal activities. Although we only present the application for rider-bicycle interactions, the proposed estimation scheme is readily extended and used for other types of human-machine interactions.

Program Library

A digital computer program has been developed to calculate dimensional and inertial properties of the human body. The program has been designed so that the user may either select a data set from a program library, or compute a data set from a geometric man-model. From primary program inputs of sex, standing height, seated height, and weight, the routines compute body segment link lengths, contact surface dimensions, masses, and moments of inertia from inputted sets of anthropometric data. Overall validity of the formulation and techniques has been established by comparing computed results with measurements on the human body reported by various investigators.

Impact Injury

An anatomically based coordinate system is a useful tool for standardizing the placement of instrumentation on segments of the human body or human surrogate. It is suggested that this system be based upon a fixed set of anatomical landmarks that are easily located by palpation and/or x-ray. A set of coordinate systems for the head, torso and extremities is proposed. Such systems will aid investigators in comparing data acquired at different laboratories involved in impact injury research. These systems can also be used for accurately locating the center of gravity of a body segment and for describing body motion in an impact environment.
