The KISS & GO! project aims to improve passive bilingualism in the population near the Italian-Slovenian border through cross-border events in shopping malls. Using an innovative approach based on IT technologies and direct interactions, partners will implement an app to informally discover the neighbor's language. Outputs include an interactive multimedia installation, a play-based language teaching app, a mini-dictionary of common dialect terms, and a promotional campaign with visual gadgets to promote bilingualism. The goal is to increase interest in minority language learning and improve the perception of language use in the cross-border territory.
