The biomechanics of human motion is a fascinating field. Who among us has never marveled at the graceful motions of a dancer or the rapid finger movements of a musician? From the time of Aristotle onward there have been countless books written on the topic of movement in animals and humans. Despite the great minds that have considered the topic, it is just recently that much advancement has bee...

The part of (bio)mechanics that studies the interaction of forces on the human skeletal system and its effect on the resulting movement is called rigid body dynamics. Some basic concepts are presented: A mathematical formulation to describe human movement and how this relates on the mechanical loads acting on the skeletal system. These equations of motion depend on the mechanical properties of ...

It long has been appreciated that humans behave irrationally in economic decisions under risk: they fail to objectively consider uncertainty, costs, and rewards and instead exhibit risk-seeking or risk-averse behavior. We hypothesize that poor estimates of motor variability (influenced by motor task) and distorted probability weighting (influenced by relevant emotional processes) contribute to ...

The vast availability ofmobile phoneswith built-inmovement and location sensors enables the collection of detailed information about human movement even indoors. As mobility is a key element of many processes and activities, an interesting class of information to extract is movement patterns that quantify how humans move, interact and group. In this paper we propose methods for detecting two co...
