This work focuses on how we can improve automatic evaluation based on guidelines inspection throughout the life cycle of Web applications by mapping guideline concepts to different artifacts produced during the development process. In order to support such an evaluation approach, we present a tool for automated evaluation based on guidelines reviews [ABSTRACT FROM AUTHOR]

In this paper we describe MultiModal WebRemUsine, a tool for remote usability evaluation of Web sites that considers data regarding the user behavior coming from multiple sources. The tool performs an automatic evaluation of the usability of the considered Web site by comparing such data with that contained in the task model associated with the pages (which describes the expected behavior of the user). The results of the analysis are provided along with information regarding the user behavior during the task performance. Using such information, evaluators can identify problematic parts of the Web site and make improvements, when necessary. An example of application of the proposed method is also discussed in the paper [ABSTRACT FROM AUTHOR]

The need for checking both usability and accessibility of Web sites is widely recognized, approved and recommended by several official organizations. What should really be more recognized or addressed is an equal need for repairing the usability and accessibility defects that have been detected. Within the Destine suite, we developed a tool allowing to repair the HTML source code of a page with user interaction. Thanks to an improved version of the Guideline Definition Language (GDL), the accessibility guidelines are not hard-coded, so that our tool can deal with any existing or future standards [ABSTRACT FROM AUTHOR]

Software Engineering community has been interested in defining methods and processes to develop software by specifying its data and behavior, but disregarding user interaction. Human-Computer Interaction community has defined techniques oriented to the modeling of the interaction between the user and the system, proposing user-oriented software constructions. In this paper, we show how to lay proper bridges between both visions, by integrating a CTT task model into a sound, model-based software development process. This proposal is underpinned by the MDA-based technology OlivaNova Method Execution, which makes software generation a reality, while still taking the user interaction needs into account [ABSTRACT FROM AUTHOR]

Task modeling has become one of the cornerstones of model-based user interface design. In this paper, a task-based approach to user interfaces design is introduced. This approach is supported by a tool, namely IdealXML, that allows for the animation of the specified user interfaces to generate a hi-fi prototype of the future user interface while still in the first development stages [ABSTRACT FROM AUTHOR]

The design of user interfaces is a step which takes a long time. The automatic generation of these interfaces induces shorter durations. With this automatic generation, the UIDLs have appeared. They allow specifying an interface using a Description Language. A step which also takes a long time is the redesigning of the user interface to take into accounts users remarks. We propose to use the operators of the tree algebra with a UIDL as UsiXML which is structured as a tree to improve this step of design. These operators help the designer to modify the interfaces and to reuse parts of interfaces. We have estimated the saving of time in two case studies [ABSTRACT FROM AUTHOR]

Although many methods have been proposed, model-based development methods have only to some extent been adopted for UI design. In particular, they are not easy to combine with user-centered design methods. In this paper, we present a hybrid UI modeling and GUI prototyping tool, which is designed to fit better with IS development and UI design traditions. The tool includes a diagram editor for domain and UI models and an execution engine that integrates UI behavior, live UI components and sample data. Thus, both model-based user interface design and prototyping-based iterative design are supported [ABSTRACT FROM AUTHOR]

The Model Driven Development has its foundations on metamodeling and new tools are required in order to support users on the definition and customization of their modeling languages. The MetaSketch Editor takes advantage of the current OMG technology to provide the metamodeling mechanisms required to support the integration of some widely used human-computer interaction (HCI) notation into the UML, through precise and semantically sound metamodeling extensions. With this integration, HCI field could contribute to leverage the model-driven development paradigm and support automatic generation of interactive applications [ABSTRACT FROM AUTHOR]

We present a system for designing Internet based applications that automatically adapt to different devices. We define a model that describes the user interaction in terms of elementary input/output actions. Then, we model devices to implements the user interaction in a multi-device context. Finally, we model users, to further adapt the interface [ABSTRACT FROM AUTHOR]

We present a rendering engine for displaying graphical user interfaces on multiple devices. The renderer interprets a standardized XML-based user interface description language: the User Interface Markup Language (UIML). A generic architecture for the renderer is defined so that deployment of the engine on different devices implies only little effort. We show that our rendering engine can be used on iDTV set-top boxes, mobile phones, PDAs and desktop PCs, and smoothly integrates with both local and remote application logic. As a test bed for the UIML specification we also explore support for extensions to UIML that enable the user interface designer to maximize accessibility and target multiple devices and different types of users at once [ABSTRACT FROM AUTHOR]

Three types of representation are typically produced during the User Interface (UI) development life cycle: a conceptual representation holding the models used for elaborating a UI, an internal representation concerning the code of the UI, and an external representation expressing the look and feel of the UI. While the end user typically manipulates the external representation only, the designer and the developer respectively focus on the conceptual and internal representations. The Comets Inspector gathers all three representations into a single environment, thus providing the user (actually, the designer and the developer; in the future, the end-user) with multiple views of a same UI simultaneously. Each representation is made observable and modifiable through one or many "mini-UIs". Consistency is ensured through mappings between these representations. From a methodological point of view, the benefit is the integration of three stakeholders' perspectives in a consensual and consistent way, enabling the exploration and manipulation of design alternatives at run time. In particular, when the context of use will be changing, the end-user will be able to inspect the UI capabilities and control its adaptation, thus sustaining explicit plasticity [ABSTRACT FROM AUTHOR]

This paper introduces a software tool for rapid prototyping of interactive systems whose user interfaces could be distributed according to four axes defined in a design space: type of computing platform, amount of interaction surfaces, type of interaction surface, and type of user interface. This software is based on a virtual toolkit for rendering the user interfaces in a virtual world depicting the real world in which the distribution occurs. The virtual toolkit consists of a layer for rendering a concrete user interface specified in a user interface description language. This paper presents its extension to modeling the external environment in terms of the design space so as to render the context of use in which the user interfaces are distributed. For each axis, a pair of functions enables exploring the axis in decreasing and increasing order so as to explore various situations of distribution, axis by axis, or in a combined way. As the interfaces resulting from this rendering are truly executable ones, this system provides designers with an acceptable means for generating ideas about how a user interface can be distributed in a context of use, and helps to evaluate the quality of a solution at an early design stage. Four representative situations located on the design space are implemented and discussed: distribution in a multi-platform context, distribution of the workplace, ubiquitous computing, and ambient intelligence, thus proving the coverage of the design space and the capabilities of the whole system [ABSTRACT FROM AUTHOR]

This article describes how the development of user interfaces for different devices can be improved and accelerated by integrating design support methods into the interactive design process that are based on a transformational consistency measure [ABSTRACT FROM AUTHOR]

One of the main goals of the Internet is to disseminate information, which grows fast and the need to maintain it up-to-date is fundamental. The advent of mobile devices and the growth of resources for these devices, as a way to access the Internet, are re-directing software companies to design multi-device user interfaces to disseminate information. There is a challenge in this situation: how to update information on the Internet in an easy and fast manner, and also that can be accessed through various devices? This research consists in developing a system to support the publication and edition of content for the web, which includes a flow of activities that makes it possible to create this content to various devices [ABSTRACT FROM AUTHOR]
