In this greatly reworked second edition of Engineering Haptic Devices the psychophysic content has been thoroughly revised and updated. Chapters on haptic interaction, system structures and design methodology were rewritten from scratch to include further basic principles and recent findings. New chapters on the evaluation of haptic systems and the design of three exemplary haptic systems from science and industry have been added.This book was written for students and engineers that are faced with the development of a task-specific haptic system. It is a reference book for the basics of haptic interaction and existing haptic systems and methods as well as an excellent source of information for technical questions arising in the design process of systems and components.Divided into two parts, part 1 contains typical application areas of haptic systems and a thorough analysis of haptics as an interaction modality. The role of the user in the design of haptic systems is discussed and relevant design and development stages are outlined. Part II presents all relevant problems in the design of haptic systems including general system and control structures, kinematic structures, actuator principles and sensors for force and kinematic measures. Further chapters examine interfaces and software development for virtual reality simulations.

This is an open access book.In this third edition of Engineering Haptic Devices the software part was rewritten from scratch and now includes even more details on tactile and texture interaction modalities. The kinematics section was improved to extend beyond a pure knowledge explanation to a comprehensive guideline on how to actually do and implement haptic kinematic functions. The control section was reworked incorporating some hands-on experience on control implementation on haptic systems. The system, actuator and sensor design chapters were updated to allow easier access to the content.This book is written for students and engineers faced with the development of a task-specific haptic system. Now 14 years after its first edition, it is still a reference for the basics of haptic interaction and existing haptic systems and methods as well as an excellent source of information for technical questions arising in the design process of systems and components. Following a system engineering approach, it is divided into two parts with Part I containing background and reference information as a knowledge basis. Typical application areas of haptic systems and a thorough analysis of haptics as an interaction modality are introduced. The role of users in the design of haptic systems is discussed and relevant design and development stages are outlined. Part II presents all related challenges in the design of haptic systems including general system architecture and control structures, kinematics, actuator principles and all types of sensors you may encounter doing haptic device development. Beside these hardware and mechanical topics, further chapters examine state-of-the-art interfaces to operate the devices, and hardware and software development to push haptic systems to their limits.

This open access book constitutes the proceedings of the 13th International Conference on Human Haptic Sensing and Touch Enabled Computer Applications, EuroHaptics 2022, held in Hamburg, Germany, in May 2022. The 36 regular papers included in this book were carefully reviewed and selected from 129 submissions.

„Entwicklung Haptischer Geräte“ legt den Schwerpunkt auf die technologischen Aspekte der Geräte, die unsere haptische Wahrnehmung beeinflussen und ermöglicht Ingenieuren und Naturwissenschaftlern eine umfassende Einführung in dieses weite und interdisziplinäre Themenfeld. Den Einstieg erleichtert ein Einblick in die Definition der Haptik aus psychologischer Sicht, gefolgt von einem Blick auf die Haptik im Alltag um ihre Bedeutung besser verstehen zu können, aber auch um ihren Verlust zu bemerken. Über die Definition einer einheitlichen Terminologie werden mit anschaulichen Beispielen aus den biologischen Kenndaten haptischer Wahrnehmung die Parameter abgeleitet, deren Verständnis für die spätere Produktentwicklung notwendig ist. Basierend darauf werden grundlegende Gerätekonzepte vorgestellt und die wesentlichen Komponenten eines haptischen Gerätes eingeführt und in Beziehung zueinander gesetzt. Daraus ergeben sich empfohlene Entscheidungswege für die Entwicklung, die ausführlich beschrieben werden. Anschließend werden sehr konkrete technische Betrachtungen aller relevanten Komponenten und Strukturen durchgeführt. Begonnen wird dies über die übergeordneten Themen der Regelungstechnik sowie den Kinematikentwurf. Anschließend werden Aktortechnologien von elektrodynamischen Systemen bis hin zu Ultraschall- und Polymeraktoren in Entwurf und Auslegung sowie für deren Einsatz in haptischen Systemen diskutiert. Im Bereich Sensortechnik bildet die für rückgekoppelte Systeme besonders relevante Kraftsensorik einen Schwerpunkt. Die Schnittstellen zur Anbindung der Geräte zu umgebenden Systemen sowie die Positionsmesstechnik runden den Hardware-Geräteentwurf ab. Ein Kapitel zu den Grundzügen des Softwareentwurfs für die haptische Interaktion bei der Simulation virtueller Welten gibt einen Einblick in die informationstechnischen Fragestellungen haptischer Entwicklungen.Die Summe dieser Abschnitte in dem Fokus eines technischenEntwicklungsprozesses stellt die wichtigsten Inhalte der Technologie und Methodik zu ihrer Nutzung klar dar, so dass vom Leser eine Einschätzung der Relevanz bezogen auf das eigene Problem getroffen werden kann.Das Buch dient also sowohl als Nachschlagewerk für Haptik-relevante Technologien, sowie als Lehrbuch, um Methodiken im Umgang mit ingenieurtechnischen Fragestellung in der Haptik zu definieren und deren Anwendung zu zeigen.

In this book, we aim to give a thorough introduction to machine dynamics. It covers the theoretical basis of dynamics, modelling, mechanical design, practical applications, kinematics and kinetics, principles of mechanics, equations of motion for multibody systems, applications to mechanisms, vehicle dynamics, and static and dynamic balancing.
