This article presents the methodological process of creation in the development of the V.S.C.O (Ocular Control Video Synthesizer) software, which is the result of the research-creation project of the same name that gathers evaluation results of its prototype through user-centered design (UCD) tools. The user-software interface is also part of the conceptualization of an artwork that operates in the context of digital art and computational art. The descriptive methodology and mixed approach will allow, through the collection of user data, to delve into the public/player experience that integrates a typology of play in the field of creation and entertainment, thus demonstrating in a perceptual evaluation of the digital artwork how it promotes states of mental relaxation in the audience. The connection between sound and visuals in the V.S.C.O computational system is also appreciated, aligning with the aesthetic and technical purposes of Visual Music, an aesthetic that dates back to the early 20th century and aimed to create a temporal architecture realized in the synesthetic fusion of colors, shapes, and movements. It is expected that the visual and auditory dynamics of the V.S.C.O, through its interaction capabilities with the audience in space, will construct its own temporal architecture, linking it with the technical and poetic aspects of Visual Music.

Usability plays a key role in increasing user satisfaction and provides numerous benefits to websites. Successful and easy-to-use sites are the result of a user-centered design process with a strong emphasis on usability assessment, a task that can be lengthy and costly. To deal with this situation, we present the development of an evaluation process with a heuristic approach based on the usability components defined by J. Nielsen (Learning, Efficiency, Memorization, Error Prevention and Satisfaction), to which we apply knowledge discovery techniques to determine the relationships between different heuristics and components, in order to discover patterns in usability problems. Five studies were performed to find different types of relationships using data mining techniques, obtaining several patterns that designers or developers could use to prioritize their efforts in improving websites, either in user interface designs or in features they offer.

The cognitive perception of scenes or objects of large or very small size, such as the architecture of a building or the anatomy of a cell, is based mainly on the visual appreciation of the scene or object through photographs, computer images, or the physical presence. However, in the case of visually impaired people, visual appreciation cannot be used, so the cognitive process is based on auditory and tactile appreciation. Nevertheless, tactile appreciation is practically impossible when dealing with very small or extremely large objects or scenes. In this work, the use of the tactile appreciation by computer, also known as digital touch or virtual touch, is proposed as an educational communication strategy for people with visual disabilities. Digital tactile appreciation is achieved with haptic systems, which add the sense of touch to the human-computer interaction, allowing the user to touch or feel virtual scenes or objects. The results obtained show that participants with visual disabilities can learn to identify objects using digital touch by computer. [ABSTRACT FROM AUTHOR]

From Moore's three interactions of distance education, Hillman, Willis & Gunawardena (1994) proposed a technological interaction in the instructional domain, the learner-interface interaction. Twenty-six years after their proposal, due to the high degree of technologization of educational technology due to its link with artificial intelligence, this interaction is more valid than ever. This article develops the past, present and future of this fourth interaction. The three most important technological areas related to education are presented, for the future development of the learner-interface interaction: Evaluation of technological interactions in the learning domain (Usability and user experience), Capabilities of intelligent educational agents (Artificial intelligence and natural language processing) and Scope of predictive algorithms in education (Deep learning and big data), as fundamental elements, although not the only ones, for the design of the next generation of 2&3D intelligent multimedia interactive interfaces for educational purposes. The need for a unified interactional model, based on the Anderson-Moore triangular interactional model, is raised, and the Anderson equivalence theorem is taken to hypothesize a possible future scenario in the short, medium and long term for highly technological education.

El poder de las computadoras se ha extendido más allá del simple procesamiento de datos, convirtiéndose en una asistente para la gestión de información. Mantener protegida la información, díganse los datos personales, es objetivo común de productores, clientes y usuarios finales del software. Esta es una ardua tarea, aún más, si se considera el volumen de datos personales manejados por software actualmente. El principio de Protección por Diseño, promueve una visión de futuro donde la privacidad no puede ser garantizada sólo a través del cumplimiento de los marcos regulatorios; más bien, debe convertirse en el modo de operación predeterminado de cada organización. La presente investigación pretende demostrar que la implementación del principio de Protección por Diseño en el proceso de desarrollo de software, desde etapas tempranas del proceso y manteniendo una estrecha vinculación con el usuario final, permitirá garantizar la seguridad del producto resultante. El resultado más relevante fue la obtención de un marco conceptual, evidenciando la relación bidireccional existente entre el principio de Protección por Diseño, la calidad de software y la satisfacción del usuario final.

This paper presents a characterization of the proposal related to user interface development for interactive systems based on the distribution of video content. The characterization is stablished related to different perspectives in the domain of software engineering and in the context of the Human-Computer Interaction (HCI). These perspectives are notation, process, tools, HCI, and validation. A characterization method is established to achieve results, which once applied, shows the strengths and weaknesses of the proposals related to each perspective as well as possible improvement and integration. Future works are presented as a result of the characterization. [ABSTRACT FROM AUTHOR]

In this work, a combination of two areas is proposed that offer ideal conditions to approach new challenges with the objective of creating new algorithms and interaction systems for the discovery of novel knowledge through data analysis. Data that comes from sensors, mobile devices, social networks, images, digital videos, purchase records, banking transactions, mobile and ubiquitous computing, among others. Making sense of these data remains a fundamental challenge, so one of the great challenges is the analysis of these complex data volumes, which require new, efficient and easy to use solutions for their manipulation and understanding. In this sense, the synergistic combination of processes, approaches, and methods of two originally separated areas, data mining and human-computer interaction, has an impact not only on academia but on society, which could be a knowledge field important in the science and technology. The purpose is to promote research for the development of new algorithms and user-centered interactive systems, with the main objective of improving human interaction, representation, and visualization of new data patterns of valid and potentially useful, as support in decision-making. In this case, the starting point is pattern recognition through visual data analysis. [ABSTRACT FROM AUTHOR]

There are diseases that make it difficult to use computational tools efficiently. Of course, some entities and research centers develop software applications to facilitate access to the use of equipment to people suffering from diseases that significantly alter their motor skills. For the software product to perform the functions for which it was designed, some tests are performed. One of them is the usability evaluation of the software, which is often done in an empirical way. This article proposes a method with a heuristic approach to evaluate the utility of software designed to facilitate access to computing for people with motor disabilities. Often, in useful subjects, a developer who does not know the specific needs of the people mistakenly approaches the guidelines in the design of the software. This research makes the importance for what users with pathologies assign weights to the characteristics of the software that experts in usability consider important. [ABSTRACT FROM AUTHOR]

Use cases (UC) have traditionally been applied by software development teams as a technical and administrative tool. From each of these perspectives, it is necessary to have a set of attributes to manage, because the information taken for the development of a software product contains information from both the system and the organization. If all this information is intended to be captured through the uc, probably what results is a significant increase in the complexity of its specification, which creates some level of confusion when using them. In this paper we propose the separation of business and technical elements, when drafting uc, using the ATx. We are introducing the ATx in modeling with uc to reduce its complexity and mainly to increase their effectiveness and usefulness in what has to do with the human computer interaction.

Nowadays, the term user experience (Ux) is widely used by Interactive Design in order to determine the acceptance by the users when they interact with any technological product. However, for some time now, different fields have used this term with different approaches, generating an increment of studies with no epistemological grounds, making it difficult to determine its true origins and research dimensions. This article explores the evolution of the user experience from the human - computer interaction (HCI), computer information systems, and the theory of design order to propose three research topics on the subject.

Information architects are mostly focused on the conceptual modeling and analysis of non-functional aspects in the early stages of interactive web projects. The resulting output is then processed by software engineers to design the needed web interface. However, this flow of information is somehow difficult to automate due to the implicit differences in the conceptual level of information processed by each expert. In order to facilitate this flow of information we propose a tool called Interarch, which helps to establish bridges between the information processed by both professionals, automatically creating analysis and design information for software engineers from the content models created by the information professionals.

The terminology used in biomedicine has lexical characteristics that have required the elaboration of terminological resources and information retrieval systems with specific functionalities. The main characteristics are the high rates of synonymy and homonymy, due to phenomena such as the proliferation of polysemic acronyms and their interaction with common language. Information retrieval systems in the biomedical domain use techniques oriented to the treatment of these lexical peculiarities. In this paper we review some of these techniques, such as the application of Natural Language Processing (BioNLP), the incorporation of lexical-semantic resources, and the application of Named Entity Recognition (BioNER). Finally, we present the evaluation methods adopted to assess the suitability of these techniques for retrieving biomedical resources. [ABSTRACT FROM AUTHOR]

This essay examines the relationship between player and diegetic sound FX in immersive computer game environments and how this relationship leads, in large part, to the contextualization of the player within the virtual world of the game. This contextualization presupposes a primarily sonically-based perception of objects and events in the world and, in a multi-player game, this ultimately leads to communication between players through the medium of diegetic sound. The players' engagement with, and immersion in, the game's acoustic environment is the result of a relationship with sound that is technologically mediated. The game engine, for example, produces a range of environmental or ambient sounds and almost every player action has a corresponding sound. A variety of relevant theories and disciplines are assessed for the methodological basis of the points raised, such as film sound theory and sonification, and, throughout, the First-Person Shooter sub-genre is used as an exemplar. Such games include the «Doom» and «Quake» series, the «Half-Life» series and derivatives and later games such as «Left 4 Dead». The combination of the acoustic environment, the interactive placement of the player - as embodied by his virtual, prosthetic arms - in the environment and the sonic relationships between players produces the acoustic ecology. An exposition of this multi-player communication and the resultant acoustic ecology and player immersion, is the main objective of the essay. [ABSTRACT FROM AUTHOR]

The article reports that generally users get to know about the information management system (SGI) while using it, which can cause problems in information retrieval. It states that the SGI interface takes into account the user, the task and the completion of the task, with the support of cognitive ergonomics, the emotional design, usability, and an evaluation of the interface project. It mentions several techniques applied to this end were the questionnaire, the interview, and card management

Multimedia is one of the less studied characteristics, probably because of the less-developed level of the digital language. Along with hypertext and interactivity, it is one of the characteristics that defines the digital edition. Those characteristics have been always studied from the point of view of production, although not so much from the point of view of reception. How do users read a digital text? The reader's participation, reading depth, different trailblazing, the relation user-interface and the conception of multimedia text as a module of a database introduce major changes in the reception of the text, which can and must be studied.

Growing development of advanced technologies demands designing, continuously, new educational strategies and instructional mechanisms to provide effective teaching and learning processes improving quality in education. As we have discussed in a recent research, the spatial factor, and how a virtual environment is perceived and experienced by the subjects, as well as the opportunities that this environment allows and encourages are all relevant factors for designing proposals for teaching and learning supported by technologies. This complex relationship is manifested throughout perceptual, emotional and socio-cognitive aspects evidenced by individuals when they are interacting with those virtual environments. Thus, this complex framework of interactions subject-virtual environment requires a deeper analysis, and at the same time new ways of understanding, different from the traditional spaces, in order to improve educational processes developed by the technologies.

User interfaces of web based online public access catalogs (OPACs) of academic, special, public and national libraries in countries belonging to Mercosur (Argentina, Brazil, Paraguay, Uruguay) are studied to provide a diagnosis of the situation of bibliographic description, subject analisis, help messages and bibliographic display. A cuali-cuantitative methodology is adopted and a checklist of systems functions created by Hildreth (1982) is updated and used as data collection tool. The resulting 38 closed questions checklist has allowed to observe the frequency of appearance of the basic functions of four areas: Area I -- operational control; Area II, search formulation control and access points; Area III, output control; and IV, user assistance: information and instruction. The study is carried out on the information obtained from 297 information units. Strata are delimited according to type of software, type of library and country. Chi square, Odds Ratio and multinomial logistic regression are applied to results. This analysis confirms the presence of significative differences according to the delimited strata and shows that most of the OPACs surveyed offer minimum capabilities. [ABSTRACT FROM AUTHOR]

The article discusses the advantages of GEMMA guide, a design guide to start and stop modes, in solving complex automation problems. The GEMMA guide is designed with considerations to include human operator as an integral part of the automation procedure, as well as the concept of cognitive ergonomic theory and human-computer interaction. The GEMMA guide also allows to smoothen the transition from academical examples to industrial setting.

El artículo discute la relación entre la ética y la estética en la interacción persona-computadora. Surge un conflicto entre los dos conceptos en cómo presentar información dentro de sistemas interactivos. Aunque este tema debería ser considerada durante el desarrollo de nuevas tecnologías, casi han desaparecido dentro de los estudios de la interacción persona-computadora.
