2 + Culture is a service design thesis aimed at strengthening cultural identity and emotional connection among second-generation Iranian immigrant families in Switzerland. Based on qualitative research, co-design sessions, and workshops with over 80 families and children, the project led to the development of a prototype app and a bilingual card game. The app offers a space for sharing experiences, parenting challenges, and Q&A among immigrant families. It helps parents connect with their children through bilingual card games, cultural exchange, and the creation of a sense of belonging. Additional features include tools for language learning, psychological support, and building support networks among parents. The ultimate goal is to reduce cultural isolation and foster belonging.
