Book Description
Ce travail de thèse présente la conception et la réalisation d'un capteur de pression 3D flexible pouvant être intégré dans un gant ou sur un outil de chirurgie pour qualifier et quantifier les forces de préhension notamment sous contraintes normales et de cisaillement. Un état de l'art présente d'abord les technologies se prêtant à cette application. Puis, le choix est porté sur la conception et le dimensionnement à partir de la loi de Hooke, d'un capteur matriciel capacitif tri-axe de 8 x 8 x 3 cellules/cm2 à partir d'un diélectrique flexible de faible module d'Young autour de 1 MPa. Les cellules conçues ont une capacité nominale voisine de 0,5 pF. Une variation de 30% est attendue à une force maximale envisagée de 100 N/cm2. La dynamique visée est de 1 à 1000. Elle correspondant à une résolution de 0,15 fF ou 100 mN/cm2. La fabrication du capteur souple est abordée en prenant en compte la caractérisation des matériaux support, notamment le Kapton, dans un flux de microfabrication. Les problèmes de métallisation et d'adhérence d'électrodes sur PDMS conduisent au développement d'un procédé basé sur la technologie de transfert de film adapté aux électrodes enfouies dans le PDMS. Des résultats de simulation sous ANSYS valident le principe physique exploité. Ils sont confirmés par des mesures électriques statiques et en charge du capteur tactile pour des forces de 10 mN à 20 N.

Book Description
The advent of augmented reality technologies used to assist human operators in complex manipulative operations—has brought an urgency to research into the modeling and training of human skills in Virtual Environments. However, modeling a specific act still represents a challenge in cognitive science. The same applies for the control of humanoid robots and the replication of skilled behavior of avatars in Virtual Environments. Skill Training in Multimodal Virtual Environments presents the scientific background, research outcomes, engineering developments, and evaluation studies conducted during the five years (2006-2011) of the project SKILLS–Multimodal Interfaces for Capturing and Transfer of Skill, funded by the European Commission under its 6th Framework Programme for Research and Technological Development. The SKILLS project evaluated how to exploit robotics and virtual environment technologies for the training of specific skills. This book details the novel approach used in the study to cope with skill acquisition, setting aside the mainstream assumptions of common computer-assisted training simulators. It explores how the SKILLS approach generated new training scenarios that allow users to practice new experiences in the performance of the devised task. Using a carefully designed approach that balances science with practicality, the book explores how virtual and augmented reality systems can be designed to address the skill transfer and training in different application contexts. The application of the same roadmap to skills originating from domains such as sports, rehabilitation, industrial environment, and surgery sets this book apart. It demonstrates how technology-oriented training conditions can yield better results than more traditional training conditions.

Book Description
Human Systems Management is an important work that integrates knowledge, management and systems into a unified world of thinking and action in business, decision-making and economics. It presents a modern synthesis of the fields of knowledge management, systems science and human organization. A biological rather than mechanistic perspective pervades the text. New and original ideas and approaches are presented with the simplicity and clarity typical of the well-known author.
