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.

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]

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.

The human being has changed in time due to both biological and cultural evolution. In a first step, biological evolution was the cornerstone of the changes in our species; later cultural evolution provided key adaptations. These adaptations include clothing, tools, reading and writing, calculation and some forms of rudimentary prosthesis. Technoscience has enhanced these adaptations conducing to a broad-sense cyborg. Our contemporary society includes a huge proportion of these latter individuals. In this article we discuss this reality and our future based on the interconnections between humans, cyborgs and robots. [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

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]

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.
