Commentary on 'scenarios and task analysis' by Dan Diaper
Paternò F.
Both Carroll's book and Diaper's paper address fundamental issues for the HCI field and stimulate important discussion that can help to clarify at least some of them. I have noticed that in recent years some tension has arisen between scenario-based approaches and task analysis, with the risk of degenerating into a kind of religious war. To some extent, the solution to this tension is simple: both approaches are important and complementary. However, this solution is often interpreted as a diplomatic, polite position in which people do not actually believe. So, some more in-depth reflections should prove to be useful.Source: Interacting with computers 14 (2002): 407–409. doi:10.1016/S0953-5438(02)00008-5

A Tool for Creating Design Models from Web Site Code
Paganelli L., Paternò F.
In this paper we present a method and the related tool for analysing Web site code in order to automatically reconstruct the underlying logical interaction design. Such design is represented through task models that describe how activities should be performed to reach users' goals. The models also include a specification of the objects that should be manipulated to accomplish such tasks. We also discuss how the result of this reverse engineering process can be provided as input to a number of tools for various purposes (model analysis, usability evaluation, user interface redesign).Source: International journal of software engineering and knowledge engineering 13 (2003): 169–189.

Understanding Interaction with Mobile Devices
Paternò F.
This editorial paper introduces an emerging and important area for human-computer interaction research, which concerns interaction with mobile devices. The design of interactive mobile applications should differ from that of traditional desktop applications. To this aim, the paper discusses some concepts and models that help to understand the new challenges as well as recently introduced techniques that can be useful for exploiting the characteristics of these devices. Lastly, tool support for the design of nomadic applications is considered, taking into account the potential contexts of use, with particular attention to the platform features.Source: Interacting with computers 15 (2003): 473–478.

Model-based tools for pervasive usability
Paternò F.
This paper aims to provide a discussion of how model-based approaches and related tools have been used to address important issues for obtaining usable interactive software and the new challenges for this research area. The paper provides an analysis of the logical descriptions that can be used in the design of interactive systems and how they can be manipulated in order to obtain useful results. This type of approach has recently raised further interest in the ubiquitous computing field for supporting the design of multi-device interfaces. The new challenges currently considered are mainly in the area of end-user development, ambient intelligence, and multimodal interfaces.Source: Interacting with computers 17 (2005): 291–315. doi:10.1016/j.intcom.2004.06.017

Collaborative social structures and task modelling integration
Penichet V. M., Paternò F., Gallud J. A., Lozano M. D.
Interdisciplinary work groups have proved to be one of the best practices (in terms of efficiency) in modern organizations. Large applications have many different users who can play different roles with responsibilities and rights depending on such roles. There are so many roles, groups, relationships among them, tasks, and collaborations, that it is very difficult to develop an application without gathering all this information in a proper way. This paper describes a modelling approach supported by a graphical notation, which makes the representation of such information easier to analyse and manage. The goal is to provide a complete and integrated approach to model collaborative interactive systems.Source: Lecture notes in computer science (2006): 180–188.

Natural modelling of interactive applications
Paternò F., Volpe N.
This paper presents an approach, and the associated environment, aiming to support designers to intuitively model interactive applications. The goal is to make modelling activity more natural. The approach is based on a transformation able to convert hand-drawn visual model sketches on boards into task-model specifications that are further editable and analysable through automatic visual tools. A first test of the environment has been carried out and has provided useful suggestions about how to improve it.Source: Lecture notes in computer science (2006): 67–77.

Designing Multi-device User Interfaces: How to Adapt to the Changing Device
Paternò F.
Nowadays, everyday life is becoming a multi-platform environment where people are surrounded by different types of devices through which they can connect to networks in different ways. Most of them are mobile personal devices carried by users moving freely about different environments populated by various other devices. Such environments raise many issues for designers and developers, such as the possibility of obtaining user interfaces able to adapt to the interaction resources of the available devices. The main learning objective is to gain knowledge and skills in methods and tools for the design of multi-device interfaces that can support designers and developers to address a number of issues raised by ubiquitous computing.Source: Human-Computer Interaction - INTERACT 2007. 11th IFIP TC 13 International Conference, pp. 702–703, Rio de Janeiro, Brazil, 10-14 September 2007

Customization of Web applications through an intelligent environment exploiting logical interface descriptions
Macias A., Paternò F.
Customization of Web-based applications is often considered a designer skill rather than an end-user need. However, there is an ongoing shift to end-user-centred technology, and even users with poor or no skill in Web-based languages may feel the need to customize Web applications according to their preferences. Although Web authoring environments have an increasing number of features, the challenge of providing end-users with the ability to easily customize entire Web applications still remains unsolved. In this paper, we propose an intelligent approach to customizing Web-based applications. Customizations rules are automatically inferred by the system from changes that users supply as examples. They remain as long-term knowledge that can be applied to support future interactions, thus minimizing the amount of authoring that end-users need to do for this purpose. In order to better understand the implications of the user's modifications, they are analysed using the logical descriptions of the corresponding Web pages.Source: Interacting with computers 20 (2008): 29–47. doi:10.1016/j.intcom.2007.07.007

Design and evaluation of an adaptive virtual guide for Web applications
Marucci L., Paternò F.
Most applications accessible through the Web suffer from a noticeable lack of support for adapting to the different information needs that different users may have regarding a certain topic. However, completely automatic adaptive support can still be confusing for users who may not understand the reasons for the dynamic change in the behaviour of an application. In this paper, we present a possible solution to provide adaptive support that does not disorient the user. The solution integrates a virtual January 18, assistant that is able to provide adaptive support in an adaptable application. We discuss an example of the application of this approach involving the support of Web visits to virtual museums. We then present the results of an empirical usability test of such an application.Source: Universal access in the information society (Print) 1 (2002): 163–175. doi:10.1007/s102090100016

The design of a handheld, location-aware guide for indoor environments
Ciavarella C., Paternò F.
Because of the growing spread of mobile and small devices (like PDAs, mobile phones, etc.), designers and developers of interactive systems have to consider user mobility and the dynamic context of use. In this paper we discuss the design criteria we have defined for developing handheld location-aware systems for indoor environments. We analyse some of the technologies currently available for this purpose and examine how to use them in order to obtain locationdependent information. We report on our experience in designing a location-aware guide for museum visitors and identify possible design criteria for this type of system, which uses automatic detection of a change in environment to trigger the presentation of multi-modal, context-dependent information through a hand-held guide.Source: Personal and ubiquitous computing (Internet) 8 (2004): 82–91. doi:10.1007/s00779-004-0265-z

From Model-based to Natural Development

Model-based approaches aim 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 discusses how they should be extended in order to obtain environments able to support real end-user development, by which designers can develop or modify interactive applications still using conceptual models but with a continuous support that facilitates their development, analysis, and use.Source: HCI International 2003, Universal Access in HCI, pp. 592–596, Heraklion, Creete, June 2003

Intelligent support for nomadic Web applications personalization
Macias J., Paternò F.
The increasing availability of different types of interaction devices raises the need of applications able to adapt to the changing interaction resources. Even systems able to generate interfaces able to adapt taking into account usability criteria may not meet all the specific user preferences. In this paper, we present an approach able to allow users to specify examples of desired changes through direct manipulation of the user interface, and then analyse such changes in order to derive general preferences. The analysis of the user changes is done at a logical level that can be useful to better identify semantic aspects in the users' request. Our approach is mostly addressed to support customization of Web nomadic applications with minimal assumptions about user programming skills.Source: INFORMATIK 2006, pp. 584–587, Dresden, September 2006
