Abstract
The Betrothed Next, here introduced as a case study, is a pilot project developed in three phases – the a geo-based urban augmented narrative (2011-15), the time-machine based on historical cartographies (2015-18) and in this last hypothesis the multimodal and multi-sensorial experience (2018-20) – of a mobile app aimed to discover the city of Milan according to an explorative and emotional perspective. In particular, the paper presents the last experimental round focused in conceiving, prototyping and assessing the the creation of a hypothetical urban soundscape crossing the tree historical thresholds – the novel (17th century), the author (19th century) and the contemporary city – to emotionally activating and interacting with people at a visceral level. The research, after exploring the state of the art and investigating the evolution of interface and interaction ecosystems in the cultural and intangible heritage field, focuses on the design of the acoustic and sound component in digital artefacts to enrich, according to a multimodal and synesthesic approach, the concept of generous interfaces.
