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]
