Abstract
Various physical or nonphysical systems can be described by states, so that the dynamics of a system is described by the state change. One of essential characters of a state is expressed by its complexity. Complexity such as entropy is a key concept in information theory. We call the study of the state change together with such complexities information dynamics (ID), which is a kind of synthesis of the dynamics of state change and complexity. Here we explain what information dynamics is and indicate how it can be used to define the dynamical entropy. Some of concrete applications of information dynamics are discussed in Chap. 8 of this volume.
