The notion of Minimalism is proposed as a theoretical tool supporting a more differentiated understanding of reduction and thus forms a standpoint that allows definition of aspects of simplicity.

Possible uses of the notion of minimalism in the field of human computer interaction design are examined both from a theoretical and empirical viewpoint, giving a range of results. Minimalism defines a radical and potentially useful perspective for design analysis. The empirical examples show that it has also proven to be a useful tool for generating and modifying concrete design techniques.

Divided into four parts this book traces the development of minimalism, defines the four types of minimalism in interaction design, looks at how to apply it and finishes with some conclusions. "

Advances in network connectivity, power consumption, and physical size create new possibilities for using interactive computing outdoors. However, moving computing outdoors can drastically change the human outdoor experience. This impact is felt in many kinds of outdoor activities such as citizen science, personal recreation, search and rescue, informal education, and others. It is also felt across outdoor settings that range from remote wilderness to crowded cities. Understanding these effects can lead to ideas, designs and systems that improve, rather than diminish, outdoor experiences. This book represents the current results emerging from recent workshops focused on HCI outdoors and held in conjunction with CHI, GROUP, UbiComp, and MobileHCI conferences. Based on feedback at those workshops, and outreach to other leaders in the field, the chapters collected were crafted to highlight methods and approaches for understanding how technologies such as handhelds, wearables, and installed standalone devices impact individuals, groups, and even communities. These findings frame new ways of thinking about HCI outdoors, explore logistical issues associated with moving computing outdoors, and probe new experiences created by involving computing in outdoor pursuits. Also important are the ways that social media has influenced preparation, experience, and reflection related to outdoor experiences. HCI Outdoors: Theory, Design, Methods and Applications is of interest to HCI researchers, HCI practitioners, and outdoor enthusiasts who want to shape future understanding and current practice related to technology in every kind of outdoor experience.

Understanding emotions is becoming ever more valuable in design, both in terms of what people prefer as well as in relation to how they behave in relation to it. Approaches to conceptualising emotions in technology design, how emotions can be operationalised and how they can be measured are paramount to ascertaining the core principles of design. Emotions in Technology Design: From Experience to Ethics provides a multi-dimensional approach to studying, designing and comprehending emotions in design. It presents emotions as understood through basic human-technology research, applied design practice, culture and aesthetics, ethical approaches to emotional design, and ethics as a cultural framework for emotions in design experience. Core elements running through the book are: cognitive science - cognitive-affective theories of emotions (i.e., Appraisal); culture - the ways in which our minds are trained to recognise, respond to and influence design; and ethics - a deep cultural framework of interpretations of good versus evil. This ethical understanding brings culture and cognition together to form genuine emotional experience. This book is essential reading for designers, technology developers, HCI and cognitive science scholars, educators and students (at both undergraduate and graduate levels) in terms of emotional design methods and tools, systematic measurement of emotion in design experience, cultural theory underpinning how emotions operate in the production and interaction of design, and how ethics influence basic (primal) and higher level emotional reactions. The broader scope equips design practitioners, developers and scholars with that 'something more' in terms of understanding how emotional experience of technology can be positioned in relation to cultural discourse and ethics.

In The Human Factor, Kim Vicente coined the term 'Human-tech' to describe a more encompassing and ambitious approach to the study of Human-Technology Interaction (HTI) than is now evident in any of its participating disciplines, such as human factors, human-computer interaction, cognitive science and engineering, industrial design, informatics or applied psychology. Observing that the way forward is 'not by widgets alone,' Vicente's Human-tech approach addresses every level-physical, psychological, team, organizational, and political-at which technology impacts quality of life, identifies a human or societal need, and then tailors technology to what we know about human nature at that level. The Human Factor was written for a broad audience, in part to educate general readers beyond the HTI community about the need to think seriously about the tremendous impact that poorly designed technology can have, ranging from user frustration to the tragic loss of human life. The articles collected in this book provide much of the technical material behind the work that was presented in The Human Factor, and the commentaries by Alex Kirlik situate these articles in their broader historical, scientific and ethical context. This collection of articles and commentaries forms a set of recommendations for how HTI research ought to broaden both its perspective and its practical, even ethical, aspirations to meet the increasingly complicated challenges of designing technology to support human work, to improve quality of life, and to design the way will live with technology. As the first book both to integrate the theory and research underlying Human-tech, and to clearly delineate the scientific challenges and ethical responsibilities that await those who either design technology for human use, or design technology that influences or even structures the working or daily lives of others, Human-tech: Ethical and Scientific Foundations will appeal to the broad range of students and scholars in all of the HTI disciplines.

This book interconnects two essential disciplines to study the perception of speech: Neuroscience and Quality of Experience, which to date have rarely been used together for the purposes of research on speech quality perception. In five key experiments, the book demonstrates the application of standard clinical methods in neurophysiology on the one hand and of methods used in fields of research concerned with speech quality perception on the other. Using this combination, the book shows that speech stimuli with different lengths and different quality impairments are accompanied by physiological reactions related to quality variations, e.g., a positive peak in an event-related potential. Furthermore, it demonstrates that - in most cases - quality impairment intensity has an impact on the intensity of physiological reactions.

Over the next few decades, millions of people, with varying backgrounds and levels of technical expertise, will have to effectively interact with robotic technologies on a daily basis. This means it will have to be possible to modify robot behavior without explicitly writing code, but instead via a small number of wearable devices or visual demonstrations. At the same time, robots will need to infer and predict humans' intentions and internal objectives on the basis of past interactions in order to provide assistance before it is explicitly requested; this is the basis of imitation learning for robotics. This book introduces readers to robotic imitation learning based on human demonstration with wearable devices. It presents an advanced calibration method for wearable sensors and fusion approaches under the Kalman filter framework, as well as a novel wearable device for capturing gestures and other motions. Furthermore it describes the wearable-device-based and vision-based imitation learning method for robotic manipulation, making it a valuable reference guide for graduate students with a basic knowledge of machine learning, and for researchers interested in wearable computing and robotic learning.

Auralization is the technique of creation and reproduction of sound on the basis of computer data. With this tool it is possible to predict the character of sound signals which are generated at the source and modified by reinforcement, propagation and transmission in systems such as rooms, buildings, vehicles or other technical devices. This book is organized as a comprehensive collection of the basics of sound and vibration, acoustic modelling, simulation, signal processing and audio reproduction. With some mathematical prerequisites, the readers will be able to follow the main strategy of auralization easily and work out their own implementations of auralization in various fields of application in architectural acoustics, acoustic engineering, sound design and virtual reality. For readers interested in basic research, the technique of auralization may be useful to create sound stimuli for specific investigations in linguistic, medical, neurological and psychological research, and in the field of human-machine interaction.
