Book Description
Nowadays, the advent of the wireless Internet and the rapid expanding of novel technologies on the mass market have represented a tremendous stimulus for pushing the development of interactive systems able to encompass support for a larger and larger variety of users, tasks, devices and contexts. In this thesis we present the benefits of using task models in the various steps of the lifecycle of an interactive application. Indeed, we show how they can play an important role in the requirements elicitation phase for example, by requiring precise definition of temporal relationships between the different activities that should be performed, so avoiding any ambiguities. Furthermore, we describe how task models may be exploited in software development beyond early analysis as they can provide valuable information for the design of interactive applications through a number of criteria specifying how to use the data contained in task models to drive the design of the user interface. Additionally, we analyse how they can be used for verification purposes, in order to check some properties of the modelled system (in combination with other models), so improving the level of confidence towards the system, which can be relevant especially in safety-critical contexts. Lastly, we show the benefits that can be gained from using task models in the usability evaluation phase, through a systematic analysis of the impact that the deviations from an expected task plan could have on the quality of the overall system.

Book Description
This book constitutes the refereed proceedings of the IFIP WG 13.2/13.5 Joint Working Conferences: 6th International Conference on Human-Centered Software Engineering, HCSE 2016, and 8th International Conference on Human Error, Safety, and System Development, HESSD 2016, held in Stockholm, Sweden, in August 2016. The 11 full papers and 14 short papers presented were carefully reviewed and selected from 32 submissions. The papers cover various topics such as integration of software engineering and user-centered design; HCI models and model-driven engineering; incorporating guidelines and principles for designing usable products in the development process; usability engineering; methods for user interface design; patterns in HCI and HCSE; software architectures for user interfaces; user interfaces for special environments; representations for design in the development process; working with iterative and agile process models in HCSE; social and organizational aspects in the software development lifecycle; human-centric software development tools; user profiles and mental models; user requirements and design constraints; and user experience and software design.

Book Description
This book covers methods for user interface design and evaluation. It shows how the systematic use of task models can make the design and development of interactive software applications easier and more effective, and how it can lead to improved usability. Useful examples of how to apply the methods will be of interest to application developers. A website containing additional exercises and pointers to relevant freeware will also be available.

Book Description
Advances in electronics, communications, and the fast growth of the Internet have made the use of a wide variety of computing devices an every day occurrence. These computing devices have different interaction styles, input/output techniques, modalities, characteristics, and contexts of use. Furthermore, users expect to access their data and run the same application from any of these devices. Two of the problems we encountered in our own work [2] in building VIs for different platforms were the different layout features and screen sizes associated with each platform and device. Dan Ol sen [13], Peter Johnson [9], and Stephen Brewster, et al. [4] all talk about problems in interaction due to the diversity of interactive platforms, devices, network services and applications. They also talk about the problems associ ated with the small screen size of hand-held devices. In comparison to desk top computers, hand-held devices will always suffer from a lack of screen real estate, so new metaphors of interaction have to be devised for such de vices. It is difficult to develop a multi-platform user interface (VI) without duplicating development effort. Developers now face the daunting task to build UIs that must work across multiple devices. There have been some ap proaches towards solving this problem of multi-platform VI development in cluding XWeb [14]. Building "plastic interfaces" [5,20] is one such method in which the VIs are designed to "withstand variations of context of use while preserving usability".

Book Description
The national information infrastructure (NII) holds the promise of connecting people of all ages and descriptionsâ€"bringing them opportunities to interact with businesses, government agencies, entertainment sources, and social networks. Whether the NII fulfills this promise for everyone depends largely on interfacesâ€"technologies by which people communicate with the computing systems of the NII. More Than Screen Deep addresses how to ensure NII access for every citizen, regardless of age, physical ability, race/ethnicity, education, ability, cognitive style, or economic level. This thoughtful document explores current issues and prioritizes research directions in creating interface technologies that accommodate every citizen's needs. The committee provides an overview of NII users, tasks, and environments and identifies the desired characteristics in every-citizen interfaces, from power and efficiency to an element of fun. The book explores: Technological advances that allow a person to communicate with a computer system. Methods for designing, evaluating, and improving interfaces to increase their ultimate utility to all people. Theories of communication and collaboration as they affect person-computer interactions and person-person interactions through the NII. Development of agents: intelligent computer systems that "understand" the user's needs and find the solutions. Offering data, examples, and expert commentary, More Than Screen Deep charts a path toward enabling the broadest-possible spectrum of citizens to interact easily and effectively with the NII. This volume will be important to policymakers, information system designers and engineers, human factors professionals, and advocates for special populations.
