Abstract
Bodily rhythms are intrinsically related to changes in behaviors. As we perform exercises, sleep, identify percepts and make decisions our bodily rhythms change. Many studies assess motions of the body but few combine motions with other physiological signals such as skin surface temperature and electrodermal activity to provide objective metrics of natural behaviors. Here we provide various examples of such physiological signals and their analyses during a variety of tasks. Specifically we examine linear and angular acceleration in relation to temperature in 20 subjects as they performed different tasks. We describe ways to transform acceleration dependent signals to velocity dependent signals in order to study the kinematics of various natural behaviors in real time. Tasks include ballet training, sports training, perceptual tasks identifying visual illusions as well as decision making when confronted with various percepts and natural gait. In all cases we compare the velocity dependent kinematics registered by high-resolution sensors to those derived form lower grain accelerometers using our algorithms. We discuss our results in light of potential applications of our technology to basic research in the perceptual sciences, so as to go beyond key presses and verbal reports.
