Mental health disorders affect the human also defined as a "Human-trace" (Galinon-Mélénec, 2011), a producer and a product of traces, regardless of their gender, age or social level. Digital, seen as culture (Doueihi, 2013), modifies the construction of sociability and of the space we inhabit. It alters our relationship to mobility in the city. With its advent, one "traces its path" (Vidal, 2015) by producing traces and data that instantly change an urban space in constant movement and expansion. By looking at disability as a variation of human development (Fougeyrollas, 2010), we study the ability of digital technology to achieve full social participation of persons with psychiatric disabilities. Inspired by Interactionism and works of the French School on Trace, our ethnomethodological research takes a closer look at social representations, communication and digital behavior of a group of people with psychiatric disabilities in a specialized habitat in Le Havre, north-west of France. Moreover we interview organizations tasked with assisting the integration of the group in social life. Our findings show a weak use of digital tools, which would normally be key in the building of the social links of these persons with the city. Based on the above, we concluded the need for a connected clubhouse offering digital education and collaborative memorial projects. This clubhouse, ideally built in partnership with public and private actors, would help the group widen its network based social participation (Saba Ayon, 2016).
