- Human-centred design integration on product developmentPublication . ALMEIDA, JOSÉ PEDRO CARDOSO DE; Campilho, Raul Duarte Salgueiral GomesThis dissertation exposes Human-Centred Design methodologies applied to product development engineering. Human-Centred Design is an approach that prioritizes the needs, behaviour and experience of the user, allowing the development of products that are aligned with user's expectations. This method integrates user’s feedback into the product development process, enabling the implementation of specific requirements that increase user’s acceptance and satisfaction. The goal is to propose a structured methodology for engineering teams to follow in the development of new industrial or consumer products, to improve not only functionality, but also intuitiveness and accessibility, resulting in an increased acceptance and satisfaction among users. To create this methodology, Industry 5.0 was analysed, to understand the role of Human-Centred Design as one of its three pillars, providing relevant inputs regarding the identified challenges and how this methodology can be designed to overcome these main issues or limitations. The state-of-the-art methods and tools were compiled from the literature review and arranged into the most appropriate timing in product development, between the stages of detail design, prototyping, and testing and refinement. With such methodology, qualitative and quantitative methods were applied to two distinct case studies, highlighting two contrasting approaches to Human-Centred Design: human-machine interaction and userproduct interaction. The uses cases were selected based on the needs identified by a Portuguese ceramic company, and all the work was conducted in partnership, including tests in the shopfloor with workers. Several user testing sessions took place throughout the mentioned product development stages, extracting user requirements from assessments including questionnaires, ergonomics and technologies such as augmented reality and eye tracking, to optimize product design on each product. This approach enabled the collection of valuable data to validate the proposed methodology, emphasizing the added value of Human-Centred Design in product development. By prioritizing user satisfaction, it enhances market acceptance and increases the success of new products. When integrated into the shop floor, this approach allows to increase new technology adoption, increasing productivity and decreasing worker's injuries. The dissertation aims to contribute to product development practice by highlighting the potential of emerging technology in facing the challenges of Human-Centred Design, in a scalable methodology encompassing the development of industrial and consumer products.
