Ultimately, the text exists to provide a definition that encompasses the intellectual facets of the field, the conceptual underpinnings of interaction design as a legitimate human-centered field, and the particular methods used by practitioners in their day-to-day experiences. This text is recommended for practicing designers: interaction designers, industrial designers, UX practitioners, graphic designers, interface designers, and managers. - Provides new and fresh insights on designing for behavior in a world of increased connectivity and mobility and how design education has evolved over the decades - Maintains the informal-yet-informative voice that made the first edition so popular

Thoughts on Interaction Design

by Jon Kolko

Thoughts on Interaction Design explores the theory behind the field of Interaction Design in a new way. It aims to provide a better definition of Interaction Design that encompasses the intellectual facets of the field and the particular methods used by practitioners in their day-to-day experiences. It also attempts to provide Interaction Designers with the vocabulary necessary to justify their existence to other team members. The book positions Interaction Design in a way that emphasizes the intellectual facets of the discipline. It discusses the role of language, argument, and rhetoric in the design of products, services, and systems. It examines various academic approaches to thinking about Design, and concludes that the Designer is a liberal artist left to infuse empathy in technologically driven products. The book also examines the tools and techniques used by practitioners. These include methods for structuring large quantities of data, ways of thinking about users, and approaches for thinking about human behavior as it unfolds over time. Finally, it introduces the idea of Interaction Design as an integral facet of the business development process.*First book to provide a solid definition and framework for the booming field of interaction design, finally giving designers the justification needed to prove their essential role on every development team *Provides designers with tools they need to operate effectively in the workplace without compromising their goals: making useable, useful, and desirable products *Outlines process, theory, practice, and challenges of interaction design – intertwined with real world stories from a variety of perspectives

A Thousand Brains: A New Theory of Intelligence

by Jeff Hawkins

A bestselling author, neuroscientist, and computer engineer unveils a theory of intelligence that will revolutionize our understanding of the brain and the future of AI. For all of neuroscience's advances, we've made little progress on its biggest question: How do simple cells in the brain create intelligence? Jeff Hawkins and his team discovered that the brain uses maplike structures to build a model of the world-not just one model, but hundreds of thousands of models of everything we know. This discovery allows Hawkins to answer important questions about how we perceive the world, why we have a sense of self, and the origin of high-level thought. A Thousand Brains heralds a revolution in the understanding of intelligence. It is a big-think book, in every sense of the word.

Three Approaches to Data Analysis: Test Theory, Rough Sets and Logical Analysis of Data (Intelligent Systems Reference Library #41)

by Igor Chikalov Vadim Lozin Irina Lozina Mikhail Moshkov Hung Son Nguyen Andrzej Skowron Beata Zielosko

In this book, the following three approaches to data analysis are presented: - Test Theory, founded by Sergei V. Yablonskii (1924-1998); the first publications appeared in 1955 and 1958,- Rough Sets, founded by Zdzisław I. Pawlak (1926-2006); the first publications appeared in 1981 and 1982,- Logical Analysis of Data, founded by Peter L. Hammer (1936-2006); the first publications appeared in 1986 and 1988.These three approaches have much in common, but researchers active in one of these areas often have a limited knowledge about the results and methods developed in the other two. On the other hand, each of the approaches shows some originality and we believe that the exchange of knowledge can stimulate further development of each of them. This can lead to new theoretical results and real-life applications and, in particular, new results based on combination of these three data analysis approaches can be expected.- Logical Analysis of Data, founded by Peter L.

Three-Dimensional Computer Vision (Symbolic Computation)

by Yoshiaki Shirai

The purpose of computer vision is to make computers capable of understanding environments from visual information. Computer vision has been an interesting theme in the field of artificial intelligence. It involves a variety of intelligent information processing: both pattern processing for extraction of meaningful symbols from visual information and symbol processing for determining what the symbols represent. The term "3D computer vision" is used if visual information has to be interpreted as three-dimensional scenes. 3D computer vision is more challenging because objects are seen from limited directions and some objects are occluded by others. In 1980, the author wrote a book "Computer Vision" in Japanese to introduce an interesting new approach to visual information processing developed so far. Since then computer vision has made remarkable progress: various rangefinders have become available, new methods have been developed to obtain 3D informa­ tion, knowledge representation frameworks have been proposed, geometric models which were developed in CAD/CAM have been used for computer vision, and so on. The progress in computer vision technology has made it possible to understand more complex 3 D scenes. There is an increasing demand for 3D computer vision. In factories, for example, automatic assembly and inspection can be realized with fewer con­ straints than conventional ones which employ two-dimensional computer vision.

Three-Dimensional Digital Tomosynthesis: Iterative Reconstruction, Artifact Reduction and Alternative Acquisition Geometry (Aktuelle Forschung Medizintechnik – Latest Research in Medical Engineering)

by Yulia Levakhina

Yulia Levakhina gives an introduction to the major challenges of image reconstruction in Digital Tomosynthesis (DT), particularly to the connection of the reconstruction problem with the incompleteness of the DT dataset. The author discusses the factors which cause the formation of limited angle artifacts and proposes how to account for them in order to improve image quality and axial resolution of modern DT. The addressed methods include a weighted non-linear back projection scheme for algebraic reconstruction and novel dual-axis acquisition geometry. All discussed algorithms and methods are supplemented by detailed illustrations, hints for practical implementation, pseudo-code, simulation results and real patient case examples.

Three-Dimensional Image Reconstruction in Radiology and Nuclear Medicine (Computational Imaging and Vision #4)

by Pierre Grangeat Jean-Louis Amans

This book contains a selection of communications presented at the Third International Meeting on Fully Three-Dimensional Image Reconstruction in Radiology and Nuclear Medicine, held 4-6 July 1995 at Domaine d' Aix-Marlioz, Aix-Ies-Bains, France. This nice resort provided an inspiring environment to hold discussions and presentations on new and developing issues. Roentgen discovered X-ray radiation in 1895 and Becquerel found natural radioactivity in 1896 : a hundred years later, this conference was focused on the applications of such radiations to explore the human body. If the physics is now fully understood, 3D imaging techniques based on ionising radiations are still progressing. These techniques include 3D Radiology, 3D X-ray Computed Tomography (3D-CT), Single Photon Emission Computed Tomography (SPECT), Positron Emission Tomography (PET). Radiology is dedicated to morphological imaging, using transmitted radiations from an external X-ray source, and nuclear medicine to functional imaging, using radiations emitted from an internal radioactive tracer. In both cases, new 3D tomographic systems will tend to use 2D detectors in order to improve the radiation detection efficiency. Taking a set of 2D acquisitions around the patient, 3D acquisitions are obtained. Then, fully 3D image reconstruction algorithms are required to recover the 3D image of the body from these projection measurements.
