Abstract: "Computing systems have changed rapidly since the first graphical user interfaces were developed. Hardware has become faster and software architectures have become more flexible and more open; a modern computing system consists of many communicating machines rather than a central host. Understanding of human-computer interaction has also become more sophisticated and places new demands on interactive software; these include, in particular, support for multi-user applications, continuous media, and 'ubiquitous' computing. The layer which binds user requirements and computing systems together, the user interface, has not changed as quickly; few user interface architectures can easily support the new requirements placed on them and few take advantage of the facilities offered by advanced computing systems. Experiences of implementing systems with unusual user interfaces have shown that current window system models are only a special case of possible user interface architectures. These window systems are too strongly tied to assumptions about how users and computers interact to provide a suitable platform for further evolution. Users and application builders may reasonably expect to be able to use multiple input and output devices as their needs arise. Experimental applications show that flexible user interface architectures, which can support multiple devices and users, can be built without excessive implementation and processing costs. This dissertation describes Gemma, a model for a new generation of interactive systems that are not confined to virtual terminals but allows collections of independent devices to be bound together for the task at hand. It provides mediated shared access to basic devices and higher-level virtual devices so that people can share computational facilities in the real world, rather than in a virtual world. An example window system shows how these features may be exploited to provide a flexible, collaborative and mobile interactive environment."

Written by international researchers in the field of Distributed User Interfaces (DUIs), this book brings together important contributions regarding collaboration and usability in Distributed User Interface settings. Throughout the thirteen chapters authors address key questions concerning how collaboration can be improved by using DUIs, including: in which situations a DUI is suitable to ease the collaboration among users; how usability standards can be used to evaluate the usability of systems based on DUIs; and accurately describe case studies and prototypes implementing these concerns. Under a collaborative scenario, users sharing common goals may take advantage of DUI environments to carry out their tasks more successfully because DUIs provide a shared environment where the users are allowed to manipulate information in the same space and at the same time. Under this hypothesis, collaborative DUI scenarios open new challenges to usability evaluation techniques and methods. Distributed User Interfaces: Collaboration and Usability presents an integrated view of different approaches related to Collaboration and Usability in Distributed User Interface settings, which demonstrate the state of the art, as well as future directions in this novel and rapidly evolving subject area.

The recent advances in display technologies and mobile devices is having an important effect on the way users interact with all kinds of devices (computers, mobile devices, laptops, tablets, and so on). These are opening up new possibilities for interaction, including the distribution of the UI (User Interface) amongst different devices, and implies that the UI can be split and composed, moved, copied or cloned among devices running the same or different operating systems. These new ways of manipulating the UI are considered under the emerging topic of Distributed User Interfaces (DUIs). DUIs are concerned with the repartition of one of many elements from one or many user interfaces in order to support one or many users to carry out one or many tasks on one or many domains in one or many contexts of use – each context of use consisting of users, platforms, and environments. The 20 chapters in the book cover between them the state-of-the-art, the foundations, and original applications of DUIs. Case studies are also included, and the book culminates with a review of interesting and novel applications that implement DUIs in different scenarios.

User Interfaces (UI) of applications, since about 2010, are usually implemented by dedicated frontend programs, following a Rich-Client architecture and are based on the Web technologies HTML, CSS and JavaScript. This approach provides great flexibility and power, but comes with an inherent great overall complexity of UIs, running on a continuously changing technology stack. This is because since over twenty years Web technologies still progress at an extremely high invention rate and unfortunately at the same time still regularly reinvent part of their self. This situation is harmless for small UIs, consisting of just a handful dialogs and having to last for just about one or two years. However, it becomes a major hurdle for large UIs, consisting of a few hundred dialogs and having to last for five or more years. This is especially the case for the complex UIs of industrial Business Information Systems. The main scientific contribution of this dissertation is the Hierarchical User Interface Component Architecture (HUICA), a scalable software architecture for Rich-Client based User Interfaces. It is primarily based on the important architecture principle Separation of Concerns (SoC), the derived idea of Hierarchical Composition, the invented design pattern Model-View-Controller/Component-Tree (MVC/CT) and the existing concepts Presentation Model and Data Binding.

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".
