Psychometric Evaluation of the F-SUS: Creation and Validation of the French Version of the System Usability Scale

ABSTRACT While the System Usability Scale (SUS) is probably one of the most widely used questionnaires to measure the perceived ease of use of interactive systems, there is currently no scientific valid translation in French. This article describes the translation and statistical validation of the French version of the SUS, called F-SUS. On the basis of two translations carried out by a committee of bilingual experts, the various psychometric analyses made it possible to select only one translation. Fidelity measurement, factor analysis and sensitivity measurement obtained results very close or similar to the original version of the SUS. Thus, the F-SUS can be used with confidence by French-speaking usability researchers and practitioners.

From excavation to drawing and from drawing to the model. The digital reconstruction of twenty-year-long excavations in the archaeological site of Bedriacum

Within technological progress and the use of interactive systems for the enhancement of Cultural Heritage, the archaeological research is witnessing a growing digitization of acquired data during the excavation phase. Considered as a fundamental medium for the reconstruction of the events that characterize an archaeological area, three-dimensional interactive models used for the documentation, conservation and musealization of excavation sites, allow to orient both the visitor and the researcher in virtual spaces, where the steps of excavation stratigraphy can be ordered and reconstructed. The creation of virtual 3D environments, aimed not only at dissemination and education but also at historical and architectural analysis, is one of the objectives of the research conducted by DAda-LAB laboratory of the University of Pavia on the archaeological site of Bedriacum, Romanvicusnear Calvatone, in the Cremona district (Italy).The twenty-year-long excavations carried out on-site by the archaeologists from the University of Milan, have discovered a complex system of built areas, villas, and structures referable to a period between the II century B.C. and the V century A.D. The central site ofBedriacum, relevant for the two wars fought in 69 A.D. for supremacy after the death of Nerone, today is not appreciable because it is completely buried.The research, co-financed by Lombardia Region, has provided the organization of drawings produced during the excavation activities within a three-dimensional system where individual actions, conducted by the archaeologists and the corresponding artifacts, were included. The three-dimensional system, in which it is possible to appreciate the ruins of the different areas at different depths, was then oriented to a 3D database obtained by laser scanner and photogrammetric survey of the entire archaeological site.Starting from the surveys conducted during the excavation campaigns, it was possible to create a new database consisting of three-dimensional representations, determining a cognitive picture of the excavation process conducted in recent years. The model highlighted the structures present in the subsoil, at different depths, which are currently not accessible. The production of three-dimensional models will support analyses and interpretations for the development of reconstructive hypotheses, enabling the creation of information tools and Virtual Reality models for the promotion of the local archaeological heritage.

Tourism 4.0 technologies and tourist experiences: a human-centered design perspective

Building on the momentum of Industry 4.0 developments in production and manufacturing, the tourism-specific concept of Tourism 4.0 currently fuels visions of similar technology-based transformations towards highly interconnected and phygital systems in the tourism industry. There is an implicit assumption that the technological innovations of Tourism 4.0 work better for the benefits of tourists. However, even marvels of tourism information technology often come with a serious lack of human-centered design. The unprecedented speed of development and implementation of Tourism 4.0 technology further adds to this neglect. In addition, traditional approaches to designing the user experience of interactive systems are now seriously challenged by the disruption of traditional views on the goals of system use, more complex user roles, and the dynamic and hybrid context of the use. The powerful capabilities of Tourism 4.0 technologies allow for the enhancement of interaction with a system and enrichment of the tourist experience itself, providing new ways of assisting in behavior change and even in the long-lasting transformation of the users. However, this also means greater potential for harm. This viewpoint conceptualizes three different effects of interactive system use on technology-mediated tourist experiences—besides goal achievement that impacts satisfaction, effects can be goal-limiting (ranging from distracting to damaging) or goal-surpassing (ranging from enhancing to transforming). This conceptualization is then used to frame the importance of human-centered design for emerging Tourism 4.0 technologies.

Defining a notation for usability-oriented interaction and navigation modeling for interactive systems

Modeling the interaction and navigation of an interactive system can assist designers in making decisions about how the users will be able to achieve their interaction goals. However, there is a lack of proposals to: (1) deal with interaction and navigation in an integrated way and (2) deal with usability features in interaction and navigation modeling. In this paper, we propose a usability-oriented interaction and navigation model to improve the quality in use of interactive systems. We evaluate the feasibility of the model through a study with three participants with experience in using models in industry, teaching models and carrying out academic research about models. Our main contributions are: (1) a knowledge base about the existing solutions for the problem, (2) the USINN (Usability-oriented Interaction and Navigation) model, (3) a preliminary evaluation about the feasibility of USINN, (4) the evolution of the USINN notation based on the results of the feasibility study, and (5) the definition of the USINN metamodel.

Supporting GUI Exploration through USS Tool

Advances in usability and design techniques (e.g. user-centered design) try to facilitate the use of interactive systems. However, users still have to adapt to interactive systems, i.e. they have to learn the steps required to accomplish a task either by trial and error or by obtaining help. While advanced users are usually able to adapt without much effort this is far from being the case with beginners. Some interactive systems offer different interaction styles in an attempt to meet the needs of all types of user but this is not the case with all interactive systems. In this sense, we present an approach to support the use of any interactive system making use of enriched models and picture-driven computing to achieve tasks automation. The USS tool (User Support System) is the basis to the adaptation of interactive systems accordingly to the users' needs. The approach provides the foundation for the addition of help (based on demonstration) to any graphical user interfaces (GUI) facilitating learning and use. The work is illustrated by a case study and completed with a preliminary user evaluation which provides insights about the validity of the approach.

Analysing situated interaction hazards: an activity-based awareness approach

This paper presents a case for the usefulness of activity theory (AT) for the analysis of situated interaction hazards in safety-related systems. It is suggested here that situation awareness is a safety critical attribute that is acquired and maintained through situated activity or actions. We introduce an activity-based awareness model based on this fundamental premise and we show how the model is consistent with the principles of AT. We also provide an example of the usefulness of AT as a theoretical and practical foundation for the analysis of situated interaction hazards in complex, safety-related systems. Specifically, we describe how the activity-based awareness model and AT principles were applied to an investigation of situation awareness in a military air traffic control system. We show how this approach can also be used to support analyses of general interactive systems use. We suggest that this general approach can be used to support analyses of interactive system use, to inform system design, and mitigate against the situated interaction hazards inherent in safety-related systems, and that this provides evidence that AT can be a useful way of looking at situational hazards in safety-related systems use.

Behavioral issues in the use of interactive systems

This paper identifies behavioral issues related to the use of interactive computersprimarily by persons who are not computer professionals, so-called “general users”. This is not an exhaustive literature survey but instead provides: (1) a structure fordiscussing issues of interactive computing, and (2) the authors' best estimate of important behavioral problems, with suggestions for solutions. The discussion is limited in this paper to general issues which do not take into account the user's particular task. The two major topics are System Characteristics (performance, facilities and on-line information), and Interface Characteristics (dialogue style, displays and graphics, other input/output media).

Aesthetic considerations for the composition and performance of computer-based jazz

Computers, critical doubts not withstanding, provide an important way to extend jazz improvisation and compositional resources. Jazz musicians have long explored the use of new technologies and have given a number of recent instruments their first virtuosos and repertoires. Just as jazz had given the saxophone its voice, through musicians like Coleman Hawkins, it also established the validity of the drum set in the work of Baby Dodds among others, and the electric guitar in the breakthroughs of Charlie Christian. I have sought to expand my work as a jazz improviser and composer through the use of interactive systems. For the past 12 years I have presented concerts that included original compositions for saxophone and computer controlled electronics. In the process I have explored several approaches to designing and performing with these systems, and addressed issues of how jazz is evolving. The lecture will include a demonstration of one such composition that uses an interactive system.

Suggestions for improving the derivation of winds from geosynchronous satellites

For more than the past two decades and for the foreseeable future measurements from geosynchronous satellites will be a major contributor to the determination of winds, especially over oceanic areas. The winds can be determined from features (e.g. clouds) that closely follow the air motion, and from the thermal wind relationship poleward of the tropics. Major improvements in accuracy and coverage should be possible during the coming decades through the combination of better sensors and their operation and the increased use of interactive systems. These data could contribute significantly to a long-term wind data base associated with global change studies.

Marketing Information Systems: Their Current Status in Fortune 1000 Companies

:A mail survey of Fortune 1000 firms reveals considerable variation in the designs of their marketing information systems, yet a uniformly high level of sophistication in regards to use of interactive systems and decision modeling. Many of the data-gathering and storage components of these systems are not computerized. The best decision support is at the upper and middle management level for planning and controlling the firm’s product offering. This top-level support indicates that the user possibly has a greater influence on system implementation than does problem structure.

Some experience in interactive system development and application

Minicomputers pgoggammed in a high-level interactive language form a very attractive basis fog the development of systems involving close man-computer collaboration. This paper is based on a wide range of experience of interactive minicomputer systems in commercial, medical, industrial, and scientific applications. It is first argued that the development of systems fog effective man-computer collaboration requires not only interactive system use but also interactive system depelopment. The designer needs to be able to tailor the system to user requirements at least partially as an experimental dialogue at a terminal with a user. There follows a critique of certain features of central computer utilities that limit their effectiveness in interactive apllications, leading to a proposal fog the use of minicomputer-based systems programmed, and used, interactively. We then give a number of case histories of our own experience in developing and using such systems in commercial, medical, and scientific appllications. From this experience, we have extracted a number of rules for programming interaction between the user and computer system which are outed. Finally, the main features of the software technology underlying these systems are briefly described.

Experimental Study of Deadline Scheduling for Interactive Systems

This paper outlines a resource allocation strategy called deadline scheduling, which is intended for use in interactive systems. Experiments are reported in which simplified versions of deadline scheduling and two time slicing strategies are modeled and compared under identical conditions. Results suggest that deadline scheduling, primarily by reducing paging overhead, provides faster response and supports more interactive users concurrently than do the two time slicing methods.
