Marsico, Maria De, Kimani, Stephen, Mirabella, Valeria, Norman, Kent L. and Catarci, Tiziana (2006): A proposal toward the development of accessible e-learning content by human involvement. In Universal Access in the Information Society, 5 (2) pp. 150-169

“Most of the existing efforts for supporting the design, preparation, and deployment of accessible e-learning applications propose guidelines that primarily address technical accessibility issues. Little, if any, consideration is given to the real actors involved in the learning experience, such as didactical experts and disabled learners. Moreover, implementing artifacts addressed to the e-learning world requires a wide range of particular skills which are related not only to technical but also to didactical, pedagogical, usability, and accessibility aspects of the produced material. This paper argues that the know-how of a number of stakeholders should be blended into a joint design activity, and that it should be possible to determine the role of each participant in the successive phases of the development lifecycle of e-learning applications. The paper sketches the methodological guidelines of a design framework based on involving the users with disabilities, as well as pedagogical experts, in the development process. The novelty of this proposal mainly stems from being built up around the core of strategies and choices specifically bound to accessibility requirements. Characteristic elements of learner-centered design are then further integrated into processes and methodologies which are typical of participatory and contextual design approaches. Following such guidelines, it will be possible to gain a deeper understanding of the requirements and of the operational context of people needing accessible material, either as learners or educators. The underlying objective is to increase the potential to realize learning systems that better meet different user needs and that provide a more satisfying learning experience. Moreover, when people get involved in the development process, they gain a sense of ownership of the system and are therefore more likely to accept and "promote" it.”

In: Proceedings of 7th conference on Human-computer interaction with mobile devices and services 2005. pp. 77-82. Available online

“Although expert-based evaluation techniques such as heuristic evaluation and cognitive walkthrough are often inexpensive and quick to apply, they have not proved to be effective in capturing contextual factors that arise in real-world settings. It is no trivial issue to understand how such evaluation techniques could be modified or differently applied so as to better take into account context, without loosing the advantages inherent in those techniques. This paper explores a possible way of addressing the trade-off between application of cognitive walkthrough and low cost improvements of its contextual validity. In particular, we propose and investigate the benefits of supporting cognitive walkthrough with video data about user interaction with an eLearning course on mobile device. Initial results from this study indicated that video data provided evaluators with a more detailed understanding of user characteristics and interaction contexts, leading to an improvement of their assessments in terms of the total number of system's flaws detected. Video data was regarded by experts as both relevant and useful, especially for tuning the evaluation focus on types of difficulties they would normally not have experienced because of differences in terms of abilities, knowledge and background with those of the target user group.”

“Different organizations adopt accessibility for various and diverse reasons. Interesting and inspiring as such reasons may be, it is important to ensure that the motivation for supporting accessibility is that it is the right thing to do, i.e. a commitment to the provision of equal opportunities for accessing resources for people with special needs. Among the various efforts for supporting the development of accessible e-learning material, most of them propose guidelines that prevalently address technical accessibility issues (such as the format and navigation of learning material) with little or no consideration for the didactical experts, and thus their didactical experience, in developing learning material. Moreover, the aforementioned guidelines tend to provide generic indications on alternative forms of didactical content for equivalent access to it. None the less, the sole provision of equivalent forms does not guarantee the retention of desirable user interface aspects and may therefore have a negative impact on learning effectiveness. While this paper acknowledges the role of such guidelines, it does propose that the didactical experts be provided with a non-technical recourse, improving their development of accessible e-learning content. By tapping into the experience of the didactical experts, this work provides them with an avenue leading to enhance the accessibility of e-learning material.”

Catarci, Tiziana, Matarazzo, Giacinto and Raiss, Gianluigi (2002): Driving usability into the public administration: the Italian experience*1. In International Journal of Human-Computer Studies, 57 (2) pp. 121-138

“The Italian Public Administration (PA) represents an important testbed for fulfilment of software usability in real settings. This is due to the volume of existing applications, the various types of ongoing projects and the potential users to whom the produced applications are addressed (both internal PA users and citizen-users). Most acquisitions of computer products in the PA are made in terms of ad hoc developments. This type of development could provide, in principle, the best condition for usability purposes, i.e. a constant contiguity between designers and users. Unfortunately, this does not lead to user-centred projects and usable products in reality. To analyse the current situation and propose improvements, the Italian authority which controls the software diffusion in PAs (Autorita per l'Informatica nella Pubblica Amministrazione -- AIPA) created a working group, the Usability Working Group -- UWG. Among the various activities of the group, two tests carried out for the PA on two different development designs of interactive systems gave several hints. The UWG also produced the guidelines for setting up PA contracts including usability as a key requirement for the interactive systems to be supplied. This paper reports the tests, compares the results with the ISO 13407 (1999) standard, and outlines the main indications coming from the proposed guidelines. Finally, the outcome and influence of the UWG activities on the PA contracts is discussed.”

“Approximately one and half year ago, the Italian authority which controls the software diffusion in Public Administrations (Autorita per l'Informatica nella Pubblica Amministrazione -- AIPA) created a working group, the Usability Working Group, with the main purposes of assessing the extent to which both suppliers of computer technologies and the public administration pay attention to product usability and of surveying the level of comfort (or discomfort) the public administration users reach when interacting with new software systems. The group had also the duty of determining possible improvements and indicating how to obtain them in the short-medium term. Among the various activities of the group, two tests carded out for the public administration on two different development designs of interactive systems gave several hints. This paper reports about such tests and their outcomes. In particular, it concentrates on: 1) work methods of the design teams; 2) participation modes of the public administration in the design process; 3) users' evaluation of the system usability with respect to their implicit and explicit needs. Finally, the lessons learned from this experience are discussed.”

“We present a prototype system to be used for visually accessing heterogeneous databases. The basic idea is to provide the user with several visual representations of data as well as multiple interaction mechanisms for both querying databases and visualizing the query results. Since some visual representations better fit certain user classes, the system adapts to the user's needs by switching to the most appropriate visual representation and interaction mechanism, according to a suitable user model. The data and query representations are consistent in every paradigm. Such a notion of consistency stems from formal basis, i.e. a twofold data/representation model, namely the Graph Model, and a set of basic Graphical Primitives. This formal approach allows the user to switch from one interaction paradigm to another, always saving the query state.”

Proceedings of the Tenth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers X August, 1995, Huddersfield, UK. pp. 151-165.

“The role of the users and their needs are now recognized in the database community. Many efforts are devoted to improve the quality of the interaction between the user and the database. For designing better interfaces that make the systems more usable, the use of suitable metaphors is crucial. The problem we address in this paper is whether an appropriate notion of metaphor can be tailored to the database interaction, so reflecting the peculiarities and needs of this specific field. Our argument originates from a recently published paper that presents a formalism whose aim is to provide a framework for flexible use, definition, and evaluation of visual metaphors in the specific case of database schemata. By discussing such a paper, we try to clarify concepts such as metaphor, data model, visual representation, etc. We also highlight some peculiarities of the database interaction. The considerations presented in this paper should constitute a basis towards a formal approach to metaphorical design for database interaction.”

Catarci, Tiziana and Santucci, Giuseppe (1995): Are Visual Query Languages Easier to Use than Traditional Ones? An Experimental Proof. In: Kirby, M. A. R., Dix, Alan J. and Finlay, Janet E. (eds.) Proceedings of the Tenth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers X August, 1995, Huddersfield, UK. pp. 323-338.

“The importance of designing query system which are effective and easy to use has been widely recognized in the database area. Also, it is well known that the adequacy of a system can be mainly tested against actual users in a well settled experiment. However, very few such experiments have been conducted. The overall objective of our study is to measure and understand the comparative ease with which subjects can construct queries in either a novel visual query language, namely QBD*, or a well-known traditional textual language such as SQL. More specifically, we are interested in determining whether there is significant interaction between: * the query class and the query language type; and * between the type of query language and the experience of the user. The analysis of the experiment results allows us to say that the effectiveness of a query language varies depending on the classes of queries and the kinds of users. However, the result trend is generally in favor of the QBD* approach, which is based on a conceptual data model, closer to the user view of the reality than the relational model, a visual representation of such a model, more attractive and graspable than a textual list of table names, and direct manipulation commands, having a syntax much easier than the SQL one.”

“One of the main problems in the database area is to define query languages characterized by both high expressive power and ease of use. In this paper, we propose a system to query databases, using diagrams as standard user interface. The system, called Query by Diagram* (QBD*), makes use of a conceptual data model, a query language on this model and a graphical user interface. The conceptual model is the Entity-Relationship Model; the query language, whose expressive power allows recursive queries, supports visual interaction. The main characteristics of the interface are the ease of use, and the availability of a rich set of primitives for schema selection and query formulation.”
