ABSTRACT
This chapter investigates the connection of participatory action research (PAR), co-design, engagement, and technologies in the current academic literature. Following PRISMA-ScR guidelines, a systematic search of academic databases was conducted in March 2025, yielding 265 results. After screening, 32 peer-reviewed studies across fields such as healthcare, human-computer interaction, communication, and sustainability were included. The data was analyzed by thematic analysis in a Google Spreadsheet where researcher triangulation was applied when coding the themes. The findings of this study reveal that PAR functions as a guiding framework for co-design, emphasizing iterative cycles, reflection, and the development of practical, needs-based solutions. Digital tools, including collaborative platforms and multimedia, support engagement and understanding. We conclude that technology-aided practices such as reflexive tool use and user feedback highlight that active user involvement enhances technology acceptance and relevance in everyday contexts.
