Abstract
This doctoral research investigates how Participatory Design can promote neurodivergent self-determination in games and play. This contribution presents an initial study on the collaborative design of an arcade game within a heterogeneous residential community situated in a social cooperative in Trento, Italy. The study explores the intersection of participatory game design, embodied and affective gameplay, and community life. The project involves co-creating a collaborative arcade game with a neurodiverse group, aiming to represent and share the lived experiences, daily routines, and spirit of conviviality that define the house. Through iterative Participatory Design workshops, participants collaboratively shape game stories, mechanics, and affective and embodied interactions using sensors and actuators. The arcade game will act as a playful orientation tool for newcomers and a medium for reflection on diversity and mutual aid. The study employs a second-person design perspective and draws insights from long-term participant observation as a residential volunteer in the cooperative. This research contributes to discussions on inclusive game design, neurodivergent self-determination, and the role of playful technologies in facilitating collaboration within heterogeneous groups.
