A taxonomy for migratory user interfaces
Berti S, Paternò F, Santoro C
Migratory user interfaces are particularly promising for forthcoming ubiquitous environments enabled by the evolution of wireless technology and the proliferation of a wide variety of interactive devices. In this paper we present a logical framework and some fundamental concepts and dimensions that can be useful to help user interface designers and developers understand migratory interfaces, analyse the state of the art, and identify areas which need further research. A number of works in this area are compared and referred to such framework and dimensions, so as to identify the advantages and drawbacks of the various approaches.

Analysing context-dependent deviations in interacting with safety-critical systems
Paternò F, Santoro C
Mobile technology is penetrating many areas of human life. This implies that the context of use can vary in many respects. We present a method that aims to support designers in managing the complex design space when considering applications with varying contexts and help them to identify solutions that support users in performing their activities while preserving usability and safety. The method is a novel combination of an analysis of both potential deviations in task performance and most suitable information representations based on distributed cognition. The originality of the contribution is in providing a conceptual tool for better understanding the impact of context of use on user interaction in safety-critical domains. In order to present our approach we provide an example in which the implications of introducing new support through mobile devices in a safety-critical system are identified and analysed in terms of potential hazards.Source: RELIABILITY ENGINEERING & SYSTEM SAFETY, vol. 91, pp. 1546-1553

Preserving rich user interface state in Web applications across various platforms
Paternò F, Santoro C, Scorcia A
This paper aims to provide thorough discussion of the aspects that compose the state of a Web application user interface, and show how it can be preserved across multiple devices with different interaction resources when the user interface dynamically migrates. The approach proposed exploits a migration server along with logical user interface descriptions.

User interface migration between mobile devices and digital TV
Paternò F, Santoro C, Scorcia A
In this paper we present a demonstration of the Migrantes environment for supporting user interface migration through different devices, including mobile ones and digital TV. The goal of the system is to furnish user interfaces that are able to migrate across different devices, in such a way as to support task continuity for the mobile user. This is obtained through a number of transformations that exploit logical descriptions of the user interfaces to be handled. The migration environment supports the automatic discovery of client devices and its architecture is based on the composition of a number of software services required to perform a migration request.

Scan and tilt: towards natural interaction for mobile museum guides
Mantyjarvi J, Paternò F, Santoro C, Salvador Z
This paper presents a new interaction technique -scan and tilt- aiming to enable a more natural interaction with mobile museum guides. Our work combines multiple modalities - gestures, physical selection, location, graphical and voice. In particular, physical selection is obtained by scanning RFID tags associated with the artworks, and tilt gestures are used to control and navigate the user interface and multimedia information. We report on how it has been applied to a mobile museum guide in order to enhance the user experience, providing details on a first user test carried out on our prototype.

A tool suite for integrating task and system models through scenarios
Navarre D, Palanque P, Paternò F, Santoro C, Bastide R
This paper presents a set of tools supporting the development of interactive systems using two different notations. One of these notations, called ConcurTaskTrees (CTT), is used for task modelling. The other notation, called Interactive Cooperative Objects (ICO), is used for system modelling. Even though these two kinds of models represent two different views of the same world (users interacting with interactive systems), they are built by different people and used independently. The aim of this paper is to propose the use of scenarios as a bridge between these two views. On the task modelling side, scenarios are seen as possible traces of activities, while on the system side, they are viewed as traces of actions. This generic approach is presented in a case study inthe domain of Air Traffic Control.

One Model, Many Interfaces
Paternò F, Santoro C
The wide variety of devices currently available, which is bound to increase in the coming years, poses a number of issues for the design cycle of interactive software applications. Model-based approaches can provide useful support in addressing this new challenge. In this paper we present and discuss a modelbased method for the design of nomadic applications showing how the use of models can support their design. The aim is to enable each interaction device to support the appropriate tasks users expect to perform and designers to develop the various device-specific application modules in a consistent manner.

Remote Web usability evaluation exploiting multimodal information on user behavior
Paternò F, Piruzza A, Santoro C
In this paper we describe MultiModal WebRemUsine, a tool for remote usability evaluation of Web sites that considers data regarding the user behaviour 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.

Reverse Engineering Cross-Modal User Interfaces for Ubiquitous Environments
Bandelloni R, Paternò F, Santoro C
Ubiquitous environments make various types of interaction platforms available to users. There is an increasing need for automatic tools able to transform user interfaces for one platform into versions suitable for a different one. To this end, it is important to have solutions able to take user interfaces for a given platform and build the corresponding logical descriptions, which can then be manipulated to obtain versions adapted to different platforms. In this paper we present a solution to this issue that is able to reverse engineer even interfaces supporting different modalities (graphical and voice).

Usability evaluation of tools for nomadic application development
Chesta C, Santoro C, Paternò F
Evaluating the usability of tools for development of nomadic applications introduces specific issues since it requires attention to both the interface of the tool itself, and the interface of the application produced through the tool. The paper addresses this problem by discussing the criteria and methodologies applied as well as the results obtained in an experimental activity on the subject.

Metodi per sistemi workflow interattivi
Paternò F, Santoro C
I sistemi di workflow hanno come obiettivo di fornire supporto automatico ai processi di un'organizzazione. Essi incorporano delle regole che definiscono come possono essere eseguite le attività delle persone, come possono comunicare tra loro, e come possono essere manipolati gli oggetti di interesse. In alcuni casi queste regole possono essere rigide ed entrare in conflitto con pattern di attività più informali e meno strutturati che contribuiscono ad un più snello svolgimento dei processi.

End User Development for Interactive Multi-Platform Applications
Paternò F, Santoro C
Natural development aims to ease building interactive software systems. Some work has been dedicated to obtaining natural programming, which aims to support programming through languages understandable by people without any specific programming skills. On the one hand, natural development implies that people should be able to work through familiar and immediately understandable representations that allow them to easily express relevant concepts, and thereby create or modify applications. On the other hand, since a software artefact needs to be precisely specified in order to be implemented, there will still be the need for environments supporting transformations from intuitive and familiar representations into precise -but more difficult to develop-descriptions.

Ad-Hoc Interactions in a Museum
Paternò F, Ciavarella C, Marucci L, Santoro C
Recent years have seen an increasing availability of interaction device types. This has posed a number of issues for identifying suitable criteria for the design of interactive software applications. At the same time, network communication technology has evolved enabling more flexible protocols for communication among dynamic sets of devices, thus opening up further possibilities. In this position paper we discuss the various levels of interactive support that is possible to make available using a museum application as case study. The aim is to enable each interaction device to support the appropriate tasks users expect to perform and designers to develop the various device-specific application modules in a consistent manner.

Improving dependability through a deviation analysis on distributed tasks in safety critical systems
Marhan A, Paterno F, Santoro C
This paper describes a method aiming to support dependability in interactive-safety critical systems. It proposes a multidisciplinary approach integrating areas usually considered separately -task modelling and distributed cognition- in order to analyse if possible deviations occurring in the performance of a system might affect its overall dependability. The basic idea is that analysis of interactive systems requires a clear understanding of the information needed to accomplish the tasks, and this information has to be derived from both internal cognitive representations and external representations provided by various types of artefacts. We illustrate our approach also applying it to a case study in the air traffic control domain.

Natural development of nomadic interfaces based on conceptual descriptions
Berti S, Paternò F, Santoro C
Natural development aims to ease the development process of interactive software systems. This can be obtained through the use of familiar representations together with intelligent environments able to map them onto corresponding implementations of interactive systems. The main motivation for model-based approaches to user interface design has been to support development through the use of meaningful abstractions in order to avoid dealing with low-level details. Despite this potential benefit, their adoption has mainly been limited to professional designers. This paper shows how they should be extended in order to achieve natural development through environments that enable end-users to create or modify interactive applications still using conceptual models, but with continuous support that facilitates their development, analysis, and use. In particular, we discuss the application of the proposed criteria to the CTTE and TERESA environments, which support the design and development of multi-device interfaces
