This study evaluates the involvement of 14 adults aged 51–78 in a co-design session aimed at safeguarding Madeiran cultural expressions using technology. Participants collaborated in groups to develop preservation strategies following an introductory session on cultural heritage. The session concluded with a presentation and collective discussion of these ideas. Audio transcriptions and a questionnaire capturing participants’ experiences and opinions, were used for thematic analysis. This research explores the interplay between culture, communication, and society, offering insights into the perception of cultural expressions over time through the theme “How adults and older adults prefer to convey cultural expressions”. Although the preferred method of transmission between participants is oral communication, it is possible to combine this same medium to promote cultural heritage through technology. Additionally, the findings inform inclusion policies and cultural programs, highlighting the role of technology and adults and older adults in fostering community and preserving cultural heritage.
