As the number of Internet users grows, the increase in smart devices interconnected through the Internet of Things (IoT) have contributed to improvements in the functionality of everyday products and enhancement of user experience. Yet, they affect user privacy and render personal data more vulnerable. To foster a digital future fully aware of user privacy requirements, a line of design research emerges that focuses on balancing product innovation with user data protection. This matter relates to sociocultural, economic, and technological aspects, and its core is a human-centered design strategy. Still, there is a gap in academic research oriented towards guiding product developers on how to consider personal data privacy concerns when designing honest IoT devices. To define this gap and delve deeper into this relevant topic, this paper presents a systematic literature review of recent academic research using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. This review focuses on prevalent research topics such as data privacy, personal data, data surveillance, and user behaviour in IoT. The result is a state-of-the-art compilation of 45 scientific studies mapping the most relevant concepts and approaches for product development in the last ten years of research, aligned with some central research questions. The Discussion and Conclusion sections provide a deep understanding of the complexity of the fast-changing landscape of privacy and personal data management using IoT products. Finally, this study proposes future academic research directions devoted to providing product designer specific, specialised help from different (yet interconnected) scientific approaches.

Product sound design is a current topic in the field of product design. It proposes the study and application of sound as one of the essential configurable parameters in the product design process, given its potential to communicate relevant and complex information to the user. In this article, we describe some of the basic principles of this discipline based on different examples and reflect on the importance of implementing specific design methodologies available for product design teams. Finally, we propose possible lines of work that can contribute to new knowledge and facilitate access to future work in this field.

El contexto de cambios de la EEES supone un reto y una oportunidad para la implantación y mejora de las titulaciones en carreras técnicas, como el grado en Diseño Industrial yDesarrollo de Producto de la Universidad de Zaragoza en el que se ha implantado la coordinación de módulos por grupos de asignaturas. Estos módulos permiten conseguir una serie de objetivos de aprendizaje y competencias por medio de los objetivos parciales de cada asignatura, permitiendo mejorar los resultados académicos y reduciendo el abandono. Los objetivos que pretende el trabajo por módulos son asegurar el resultado del aprendizaje, complementar sin solapar contenidos de asignaturas, dar sentido a todas las asignaturas independientemente de su área de conocimiento y optimizar los recursos y esfuerzos del alumno. El logro es gracias a una serie de actividades programadas por los responsables docentes de cada módulo en los que se introducen buenas prácticas como la evaluación continua y conjunta, aprendizaje basado en un proyecto común para todas las áreas de conocimiento que aproxima al alumno a la realidad profesional del diseñador.Los resultados obtenidos son muy satisfactorios para los alumnos por su mejora de aprendizaje, encontrando sentido a algunas materias técnicas que tenían difícil aplicación en diseño, y por la mejora de sus resultados académicos. Otro resultado destacado es la coordinación y la comunicación entre el profesorado que mejora el ambiente y buena disposición entre todos los miembros de la Comunidad Universitaria que intervienen en el Grado.

Purpose: This contribution describes the integration of netnography in critical contexts where traditional service design faces limitations, presenting the case of a neonatal intensive care unit clinical setting under COVID-19 pandemic restrictions. Design/methodology/approach: Under tough constraints, netnographic immersion, digital surveys and remote participatory methods replaced successfully the intended ethnographic observation research. The study follows four phases: research approach, data collection, data analysis and sharing of findings. Findings: The findings highlight the potential of netnography for service design in highly constrained environments. Digital immersion facilitated contextual understanding and iterative co-creation. This hybrid approach helps to engage stakeholders and overcome access limitations in critical ecosystems such as healthcare. Research limitations/implications: The COVID-19 emergency prolonged the data collection process longer than expected. While work continued in 2022 and 2023, the main phase of the project was carried out under significant time pressure. Practical implications: This study provides guidelines for applying netnography in critical service design contexts. In healthcare, the model developed can be adopted in projects devoted to improve patient-centered service design, optimize healthcare workflows and enhance collaboration between frontline professionals and decision-makers. Social implications: The case demonstrates that digital tools can help to bridge geographical, cultural or institutional barriers. They can also facilitate participatory design processes in critical contexts. Originality/value: Previous studies have explored ethnographic approaches in service design and netnography in digital research. This study bridges the two and offers a scalable and adaptable approach for complex, critical service environments. The study delves into the use of digital tools to develop participatory research processes.
