Many computer applications require microprocessors to reliably interconnect and communicate with other peripherals in order to perform their intended functions. Interface design, which includes the development of the methods and processes by which two or more components communicate, is a crucial step in the deployment of microprocessors in an embedded computing environment. ARM-based microprocessors are a leading technology in this field, offering a wide range of performance for different applications. This book provides a comprehensive treatment of interface design from basic logical and theoretical principles to practical implementation on an ARM-based microprocessor, addressing both hardware and software considerations. The microprocessor’s high level of complexity is carefully analysed in the text to provide clear guidance for the reader in the design of new applications, resulting in an invaluable reference resource for graduates and engineers involved in the design of electronic products and systems. Key Features: Brings together aspects of digital hardware, interface design and software integration in a single text to make clear the link between low and high level languages for interface control Categorises interface techniques into easily distinguished chapters, progressively involving greater complexity, enabling the reader to quickly find relevant material for a particular application Provides many practical C-coded examples showing both the preparation and use of complex programmable subsystems implemented in a typical commercial product Presents in each chapter an introduction to the essential theoretical aspects and the development of simple interface designs using basic logical building blocks
This is the only book that describes a complete approach to customer-centered design, from customer data to system design. Readers will be able to develop the work models that represent all aspects of customer work practices.
Technology is meant to make life easier and to raise its quality. Our interaction with technology should be designed according to human needs instead of us being required to adapt to technology. Even so, technology may change quickly and people and their habits change slowly. With the aim of supporting user acceptance of iTV, the focus of this book is on the usability of iTV applications. A method for developing interaction design patterns especially for new technologies is presented for the first time. The main characteristics covered in this new approach are: systematic identification of recurrent design problems; usability as a quality criterion for design solutions; integration of designers into the pattern development process including identification of designers' needs, and iterative evaluation and optimisation of patterns to encourage designers to accept and use them; usability testing to identify proven design solutions and their trade-offs; presentation of specific design guidelines.

As modern technologies continue to develop and evolve, the ability of users to interface with new systems becomes a paramount concern. Research into new ways for humans to make use of advanced computers and other such technologies is necessary to fully realize the potential of 21st century tools. Human-Computer Interaction: Concepts, Methodologies, Tools, and Applications gathers research on user interfaces for advanced technologies and how these interfaces can facilitate new developments in the fields of robotics, assistive technologies, and computational intelligence. This four-volume reference contains cutting-edge research for computer scientists; faculty and students of robotics, digital science, and networked communications; and clinicians invested in assistive technologies. This seminal reference work includes chapters on topics pertaining to system usability, interactive design, mobile interfaces, virtual worlds, and more.
Work practices and organizational processes vary widely and evolve constantly. The technological infrastructure has to follow, allowing or even supporting these changes. Traditional approaches to software engineering reach their limits whenever the full spectrum of user requirements cannot be anticipated or the frequency of changes makes software reengineering cycles too clumsy to address all the needs of a specific field of application. Moreover, the increasing importance of ‘infrastructural’ aspects, particularly the mutual dependencies between technologies, usages, and domain competencies, calls for a differentiation of roles beyond the classical user–designer dichotomy. End user development (EUD) addresses these issues by offering lightweight, use-time support which allows users to configure, adapt, and evolve their software by themselves. EUD is understood as a set of methods, techniques, and tools that allow users of software systems who are acting as non-professional software developers to 1 create, modify, or extend a software artifact. While programming activities by non-professional actors are an essential focus, EUD also investigates related activities such as collective understanding and sense-making of use problems and solutions, the interaction among end users with regard to the introduction and diffusion of new configurations, or delegation patterns that may also partly involve professional designers.
Despite the fact the human computer interface is the main facilitator of communication between the user and the computer system, its importance has been highly disregarded by system designers. This has resulted in many undesirable consequences, and in prescription and other healthcare systems, these problems are aggravated by the fact that not only are the users inconvenienced, but there are potential threats to the well-being of the patients under care as well. Many healthcare systems are often designed without considering the potential users of these systems. Consequently, the systems are created ad hoc, there is general dissatisfaction and eventually most of these systems are abandoned. This wastes human as well as economic resources while creating a stigma among the users towards the use of automated systems. In order to salvage one such system, different methods from the areas of usability engineering, human-computer interaction, psychology and cognitive science are considered, to systematically derive a framework to guide the redesign process. The research undertaken in this project highlights the role and significance of the human-computer interface and puts an emphasis on the importance of user involvement in interface design in order to effectively satisfy their needs. Principles and guidelines for interface design are reviewed in order to obtain the guidance necessary for successful redesign. The research also reviews the different techniques involved in the design of user-centered interfaces and filters these to a reasonable set to be applied. Results from the research review, as well as from visits conducted to other healthcare facilities in Nairobi, are also used to pinpoint best practices for designing usable prescription system interfaces. Following the gathering of this information, a series of evaluations are conducted on the abandoned system to identify the flaws that could have caused its failure. Feedback from these evaluations, user suggestions and recommendations as well as best practices are used to iteratively develop an improved prototype system. The redesigned system presents a successfully applied example of the user-centered design framework. A comparison between the original and redesigned system interfaces shows improvements in information quality, interface quality and system usability.
