The emerging information technologies have given rise to new human patterns in terms of both physiological and psychological interactions. Human Algorithms aim to model human forms, interactions, and dynamics in this new context. They are becoming increasingly comprehensive and inexpensive for use in real-world designs: inside monitors, connected to networks, and under human skin. This book aims to reflect the state-of-the-art of Digital Human Modeling, specifically emergent Human Algorithms. It constitutes a survey of innovative ideas aimed at a wide range of readers, including college students, researchers, engineers, designers, scientists, managers, and healthcare professionals. The 11 chapters are divided into three parts: Human Dynamics, Virtual Humans and Human Forms.
