Generation of User Interfaces from Business Process Model Notation (BPMN)
2019
Business Process Model Notation focuses on functional processes; so, the design of the interface generally depends on the subjective experience of the analyst. This thesis proposes a new method to generate interfaces from BPMN models. The idea is to identify rules from BPMN to interfaces in existing real projects. We have analyzed 7 Bizagi projects to generalize a list of rules. It has been done considering five BPMN patterns. Apart from BPMN primitives, there are rules that depend on elements of Class Diagrams to know how to generate the interfaces. When the rules have several alternatives to generate the interfaces, we need an unambiguous semantics to specify which alternative we are goin…
An innovative mechanical motion converter for sea wave applications
2018
The paper shows an innovative system designed and developed by University of Palermo. The device is based on a simple mechanical converter able to transform a variable bidirectional linear motion into a unidirectional rotary motion. This technology can be successful used in sea wave applications, producing a mechanical output usable for the electrical energy production.
Predicting perceived visual complexity of abstract patterns using computational measures: The influence of mirror symmetry on complexity perception
2017
Visual complexity is relevant for many areas ranging from improving usability of technical displays or websites up to understanding aesthetic experiences. Therefore, many attempts have been made to relate objective properties of images to perceived complexity in artworks and other images. It has been argued that visual complexity is a multidimensional construct mainly consisting of two dimensions: A quantitative dimension that increases complexity through number of elements, and a structural dimension representing order negatively related to complexity. The objective of this work is to study human perception of visual complexity utilizing two large independent sets of abstract patterns. A w…
Scientific Production on Web Usability
2016
Scientific literature on Web usability is presented by the bibliometric analysis of published Science and Scopus database articles available on the Web. We analyzed the productivity, temporal distribution and scientific production by authors, institutions, countries and journals. There has been a growing trend in the number of articles published, confirming the consolidation and progress in web usability research.
Bayesian Metanetwork for Context-Sensitive Feature Relevance
2006
Bayesian Networks are proven to be a comprehensive model to describe causal relationships among domain attributes with probabilistic measure of appropriate conditional dependency. However, depending on task and context, many attributes of the model might not be relevant. If a network has been learned across multiple contexts then all uncovered conditional dependencies are averaged over all contexts and cannot guarantee high predictive accuracy when applied to a concrete case. We are considering a context as a set of contextual attributes, which are not directly effect probability distribution of the target attributes, but they effect on a “relevance” of the predictive attributes towards tar…
Comprehensive Experimental Analysis of Handcrafted Descriptors for Face Recognition
2018
Over the past few decades, LBP descriptor, which shown its high robustness in extracting discriminative features from an image, has been successfully applied in diverse challenging computer vision applications including face recognition. The efficiency and usability of the LBP operator and its success in various real world applications has inspired the development of much new powerful LBP variants. Indeed, after the appearance of the LBP operator, several renowned extensions and modifications of LBP have been proposed in the literature to the point that it can be difficult to recognize their respective LBP-related strategies, strengths and weaknesses according to a given application, and th…

Web-Based Learning Objects in School Education
2010
The added value of Web-based learning objects (WBLOs) lies in supporting learners to acquire the right knowledge and skills in order to function as active and collaborative learners. To realize this, WBLOs must be both technically and pedagogically usable. Technical usability in itself is not sufficient. To support the learning process, the usability concept must be extended to include pedagogical considerations. The importance of pedagogical usability in education has been recognized, but not sufficiently researched. In addition, little research has been done to evaluate the pedagogical value of WBLOs. The main goal of this paper is to show how to foster pedagogically usable WBLOs in schoo…
Evaluation of the Measuring Active Drag system usability: An important step for its integration into training sessions
2010
This paper is the first stage of an iterative process aiming at the (re)design of a training device for swimming. The purpose of this study was to evaluate the usability of the Measuring Active Drag (MAD) system, a technical device for biomechanical evaluation and performance analysis. To do so, this study examines real activity of elite swimmers using this system. It was conducted within an activity-centred approach: the course-of-action technological research programme. Three international male swimmers volunteered to participate in the study. Two types of data were collected: (a) video recordings, and (b) verbalisations during post-protocol interviews. The data were processed in two step…
Impact of fabric end-use knowledge on handle perception
2006
Abstract The objective was to determine whether the knowledge of the fabrics' end-use may impact the way textile experts organize their haptic perception. Two groups of 10 textile experts were asked to freely sort the same set of 25 fabrics in two different contexts. The first group was informed that the set of fabrics would be used to make dresses and the other one that they would be used to make sportswear. Both groups also rated the appropriateness of each fabrics for each end-use. Results did not show any effect of the end-use context. The two perceptual spaces were basically the same and accounted for appropriateness of use similarly. If confirmed, this result indicates that descriptiv…
