In recent years, computer animated characters have become commonplace, often appearing extremely lifelike in movies, television, and video games. Unfortunately, animating digital characters remains difficult and time-consuming, pursued mostly by dedicated professionals, because conventional animation methods require careful control and coordination of many different low-level parameters which affect the believability of a character's pose and timing. In this thesis, we present techniques to allow high-level control of motions for animated human characters, by interactively editing existing locomotive motions. These techniques prioritize interactivity by allowing the user to manipulate more general or high-level aspects of the motion, such as a motion path. These techniques also have low data and computation requirements, as they operate on a single input motion without expensive optimization or simulation, allowing for instant feedback. The foundation of this work is a novel path-based editing algorithm based on simple and well-established biomechanical and physical principles of motion. After user manipulation of a motion path, the poses of the character along the path are automatically adjusted to match the new path, and an automatic timewarping procedure adjusts the timing of the new motion depending on its context, in order to remain consistent with the original even after large changes. Our two performance techniques utilize familiar input methods to control the path-based editing algorithm in different ways. First, based on a study exploring how users can express motion using their hands, our "finger walking" technique allows control of motion editing by mimicking full-body motion on a touch-sensitive tabletop. A further study was conducted to test automatic identification of the motion type of the performance, and to evaluate user satisfaction with the generated motions. The second technique uses handheld manipulation of a mobile device, such as a tablet or smartphone, to mimic a motion through space. Using only the simple and standard motion sensors in these devices, we developed two gestural methods for editing motion, with both discrete, one-off gestures and continuous "steering wheel" style control of an ongoing motion. Overall, the techniques presented in this thesis demonstrate that fast and interactive editing of human locomotion is possible using meaningful high-level controls, without requiring large amounts of additional motion data or computation.

The 14 papers in this volume vividly demonstrate the current state of research in real-time animation. Half of the papers are dedicated to algorithm allowing the real-time animation of complex articulated structure in particular (humans, legged robots, plants) and of dynamic scenes in general. The proposed approaches cover from motion capture to motion reusability which are essential issues for high-end applications as 3D games, virtual reality, etc. Other topics treated are motion management for fast design of realistic movements, 2D and 3D deformations, and various optimization techniques for simulation (adaptive mass-spring refinement, huge particule systems).

This book contains the research on modeling bodies, cloth and character based adaptation performed during the last 3 years at MIRALab at the University of Geneva. More than ten researchers have worked together in order to reach a truly 3D Virtual Try On. What we mean by Virtual Try On is the possibility of anyone to give dimensions on her predefined body and obtain her own sized shape body, select a 3D cloth and see oneself animated in Real-Time, walking along a catwalk. Some systems exist today but are unable to adapt to body dimensions, have no real-time animation of body and clothes. A truly system on the web of Virtual Try On does not exist so far. This book is an attempt to explain how to build a 3D Virtual Try On system which is now very much in demand in the clothing industry. To describe this work, the book is divided into five chapters. The first chapter contains a brief historical background of general deformation methods. It ends with a section on the 3D human body scanner systems that are used both for rapid p- totyping and statistical analyses of the human body size variations.

Virtual Humans are becoming more and more popular and used in many applications such as the entertainment industry (in both film and games) and medical applications. This comprehensive book covers all areas of this growing industry including face and body motion, body modelling, hair simulation, expressive speech simulation and facial communication, interaction with 3D objects, rendering skin and clothes and the standards for Virtual Humans. Written by a team of current and former researchers at MIRALab, University of Geneva or VRlab, EPFL, this book is the definitive guide to the area. Explains the concept of avatars and autonomous virtual actors and the main techniques to create and animate them (body and face). Presents the concepts of behavioural animation, crowd simulation, intercommunication between virtual humans, and interaction between real humans and autonomous virtual humans Addresses the advanced topics of hair representation and cloth animation with applications in fashion design Discusses the standards for Virtual Humans, such as MPEG-4 Face Animation and MPEG-4 Body Animation.
