Vigencia:
De 01/Ago/2023 hasta 10/Ago/2025

Descripción:

El objetivo del proyecto consiste en realizar el estudio para el diseño y establecimiento de un servicio de evaluación de la experiencia de usuario, usabilidad y accesibilidad de software a nivel nacional. Los servicios de este tipo son necesarios para asegurar la calidad y potenciar la usabilidad de las herramientas tecnológicas que se usan a nivel nacional. Además, ofrecer este tipo de servicios permitiría al CITIC constituirse en una unidad académica de investigación a la vanguardia, logrando potencialmente una mayor vinculación con el sector productivo. Este proyecto permitirá desarrollar la infraestructura tecnológica y las herramientas necesarias para mejorar la experiencia de usuario, usabilidad y accesibilidad del software a nivel nacional. De esta manera aspiramos a contribuir a una integración más plena del quehacer científico y la transferencia tecnológica en el área de la computación e informática.

Evaluation of Usability, User Experience and Accessibility of Applications: a Tertiary Review

Descripción:

In the present time, there is a growing need to understand how users interact with digital applications to ensure the success of new products and a good experience for the users. Three main concepts are central to this subject: usability, user experience, and accessibility. As such research efforts have been undertaken to create evaluation instruments for each and apply them to multiple tools. This study aims to perform a compilation of the research gathered in multiple secondary studies on the subject of evaluating these concepts.A systematic search process was performed to answer research questions related to how evaluations in the field of usability, user experience, and accessibility are performed. From this search 45 secondary studies were obtained and further analyzed. We were able to identify the most common methodologies and tools high-lighted across the secondary studies for each concept. The main results found were the following: questionnaires are ubiquitous in the field of user experience evaluation and to a lesser extent for usability while accessibility evaluation is mostly performed with the aid of automated tools, there is a tendency for authors to develop and use their own questionnaires without validating them and 24 main categories for the evaluated characteristics were found, of which Satisfaction, Efficiency, Effectiveness, and Attractiveness were the most common.

Smart Speakers and Intelligent Personal Assistants: Experiences, Perspectives, and UX Evaluation

Descripción:

This paper consolidates the efforts of our research group in designing and developing voice applications for smart speakers and intelligent personal assistants (such as Amazon Alexa, Google Assistant, Siri, and Cortana) over recent years. We present six case studies: a career guidance system, an application for educational fairs, an appointment booking system for a dentist's office, a set of games for seniors, a notification system for smart farming, and the use of smart speakers as mechanisms to evaluate user experience. These case studies encompass various contexts, each requiring unique approaches. Each voice application was individually evaluated using standardized questionnaires and customized surveys. Additionally, we conducted two parallel evaluations to address key questions about human interaction with intelligent personal assistants. These evaluations involved both expert groups and end-users of the voice applications. Finally, we synthesize the knowledge, experiences, and perspectives gathered over these years to present a list of lessons learned, aimed at guiding researchers and developers in enhancing the user experience (UX) of voice applications.

Improving the user experience of standardized questionnaires by incorporating gamified mechanisms

Descripción:

User experience (UX) evaluation is essential for organizations since it allows them to generate competitive advantage and ensure that the software created is in accordance with the target users. There are several UX evaluation techniques and tools for information systems, among which the most widely used are standardized written questionnaires. However, in recent years, more interactive techniques have begun to take center stage, such as gamified methodologies that seek to include gaming techniques to attract greater interest from evaluators. This research aims to analyze the use of gamified mechanisms in combination with standardized UX evaluation questionnaires, taking advantage of the already demonstrated statistical capabilities of the questionnaires and at the same time providing the novelty of gamification techniques so that the collection of evaluation responses is attractive to participants.

Current Practices in Accessibility Evaluation: A Literature Review of Over 100 Studies

Descripción:

This article aims to fill the gap in accessibility assessment practices through a comprehensive review of over 100 research articles, identifying the most commonly used accessibility assessment methods. The review includes both studies assessing the accessibility of systems and those promoting accessibility or assistive technologies. By reviewing existing research, we seek to provide a clear overview of the predominant methodologies in the field, highlighting current practices and pointing out areas for methodological improvement and innovation. The significance of this study lies in its potential to inform future research and practice, providing a basis for developing more effective and comprehensive assessment frameworks that improve accessibility for users with disabilities.
