We propose motion manifold learning and motion primitive segmentation framework for human motion synthesis from motion-captured data. High dimensional motion capture date are represented using a low dimensional representation by topology preserving network, which maps similar motion instances to the neighborhood points on the low dimensional motion manifold. Nonlinear manifold learning between ...

OBJECTIVE To apply the dual Euler angles method to investigate the passive motion characteristics of the human ankle joint complex. DESIGN Three-dimensional kinematic data of the ankle joint complex was collected from 10 knee-below foot cadaver specimens. BACKGROUND Besides the Euler angles and screw axis methods, the dual Euler angles method has been proposed as an alternative approach to ...

The use of disturbance models in wind turbine individual pitch control design to attenuate effects of persistent disturbances is investigated. Previous work has used individual pitch control and disturbance models to design controllers that reduce the blade loads at the frequencies associated with the rotor speed. This paper takes a similar approach of using a disturbance model within the H∞ de...

This study focused on student ability to analyze and interpret motion graphs following laboratory instruction that utilized interactive digital video as well as traditional instructional techniques. Particular attention was given to students’ ability to construct and interpret motion graphs. Two laboratory exercises involving motion concepts (i.e. freefall and projectile motion) were developed ...

Studies on human perception have identified pelvis and torso motion as key discriminators between male and female gaits. However, while most observers would advocate that men and women walk differently, consistent findings and explanations of sex differences in gait kinematics across modern empirical studies are rare. In the present study we evaluated sex differences in whole body gait kinemati...

Urban road safety management is usually characterized by the lack of sufficient, good quality crash data and low budgets to obtain it even though many traffic accidents occur there. For example, 54 percent of road crashes in Spain take place in urban areas, and 10 percent of urban fatal crashes occur on crosstown roads, which are rural roads that traverse small communities. Traffic calming meas...

Immersive virtual environments allow users to control their virtual viewpoint by moving the tracked head or by walking through the real world. Usually, movements in the real world are mapped one-to-one to virtual camera motions. With redirection techniques, gains are applied to user movements when the virtual camera is manipulated. Since male and female persons use different strategies for spat...

Some athletes accomplish feats requiring a timing accuracy 100 times better than their reaction time. This capability implies that the brain can accurately extrapolate the motion of objects. We hypothesize that the brain uses a simple algorithm to accomplish this extrapolation, and that the algorithm is influenced by the subject's gender and recent observations of motion. We describe an experim...

This paper investigates the use of disturbance models in the design of wind turbine individual pitch controllers. Previous work has used individual pitch control and disturbance models with the Multiblade Coordinate Transformation to design controllers that reduce the blade loads at the frequencies associated with the rotor speed. This paper takes a similar approach of using a disturbance model...
