    A Developer’s Guide to Building and Testing Accessible Mobile Apps
    (Association for Computing Machinery (ACM), 2024) Sandoval Alcocer, Juan Pablo; Merino del Campo, Leonel Alejandro; Fernandez Blanco, Alison; Ravelo Mendez, William; Escobar Velásquez, Camilo; Linares Vásquez, Mario
    Mobile applications play a relevant role in users’ daily lives by improving and easing daily processes such as commuting or making financial transactions. The aforementioned interactions enhance the usability of commonly used services. Nevertheless, the improvements should also consider special execution environments such as weak network connections or special requirements inherited from the user’s condition. Due to this, the design of mobile applications should be driven by improving the user experience. This tutorial targets the usage of inclusive and accessibility design in the development process of mobile apps. Making sure that applications are accessible to all users, regardless of disabilities, is not just about following the law or fulfilling ethical obligations; it is crucial in creating inclusive and fair digital environments. This tutorial will educate participants on accessibility principles and the available tools. They will gain practical experience with specific Android and iOS platform features, as well as become acquainted with state-of-the-art automated and manual testing tools.

    Controlling Trajectories with OneButton and Rhythm
    (Association for Computing Machinery, 2024) Bellino, Alessio; Rocchesso, Davide
    We demonstrate two-dimensional navigation with velocity control on a single button. Users can vary the speed of the controlled object by rhythm tapping, and can control direction by pressing and tilting, releasing the button once the desired rotation is achieved. Feedback is multisensory. Tactile pulses are being delivered at 30-degree intervals during rotation, simulating the detents of a rotary encoder. Simultaneously, a sonic glissando accompanies rotation, raising or lowering pitch according to the change of direction. Absolute positional feedback is provided visually as well as auditorilly, with an intermittent auditory tone whose pitch conveys vertical position, panned to the left or to the right depending on horizontal position. The rhythmic pace corresponds directly to the on-screen element speed, defined by the tapping interval. Participants will be engaged in a target-following task, thus being able to appreciate the precise speed and direction control of the multisensory navigation experience.

    Exact classification of nmr spectra from nmr signals
    (Institute of Electrical and Electronics Engineers Inc., 2024) Lehmann, Pedro Izquierdo; Xavier, Aline; Andia Kohnenkampf, Marcelo Edgardo; Sing Long Collao, Carlos Alberto
    Nuclear magnetic resonance (NMR) spectroscopy is routinely used to study the properties of matter. Therefore, different materials can be classified according to their NMR spectra. However, the NMR spectra cannot be observed directly, and only the NMR signal, which is a sum of complex exponentials, is directly observable in practice. A popular approach to recover the spectrum is to perform harmonic retrieval, i.e., to reconstruct exactly the spectrum from the NMR signal. However, even when this approach fails, the spectrum might still be classified accurately. In this work, we model the spectrum as an atomic measure to study the performance of classifying the spectrum from the NMR signal, and to determine how it degrades in the presence of additive noise and changes in field intensity. Although we focus on NMR signals, our results are broadly applicable to sum-of-exponential signals. We show numerical results illustrating our claims.

    Normalización terminológica en el ámbito de los bienes patrimoniales chilenos: del corpus a la plataforma web (Short Paper)
    (2024) Montero Casado, Ignacia Andrea; Tebé Soriano, Carles; Pissolato de Oliveira, Luciana
    En esta ponencia se aborda el proceso de normalización terminológica en un corpus monolingüe en español de Chile del ámbito de la conservación-restauración de bienes patrimoniales realizado en el marco del proyecto FONDEF IDeA I+D “Plataforma para la identificación de las alteraciones a los bienes patrimoniales chilenos”. En específico, se explicarán las etapas metodológicas que constituyen el proceso de normalización: 1) constitución del corpus, 2) extracción de información terminológica del corpus, 3) preparación de los materiales para la sesión de normalización, 4) las sesiones de normalización y 5) elaboración del dossier de salida, previas a la etapa de transición que corresponde al traslado de los resultados de la normalización a la plataforma web. El objetivo de este proceso de normalización es obtener términos relativos a conceptos de alteraciones de los bienes patrimoniales chilenos bien delimitados y consensuados por los especialistas del ámbito para la creación de una base de datos terminológica accesible mediante una plataforma web. La singularidad de la normalización llevada a cabo es que, si bien las decisiones finales recaen en los especialistas del ámbito, el proceso para llegar a esas decisiones está guiado por terminólogos. Esta ponencia se centrará en presentar las particularidades y desafíos que surgieron en las diferentes etapas y las soluciones adoptadas en cada una de ellas, y relacionarlas con las características del ámbito disciplinar, del corpus y con los objetivos y necesidades del proyecto
