This article explores the development and implementation of strategic devices to shape prospective futures in contexts of vulnerability, highlighting the importance of understanding the complexity of existential structures and the systemic relationship between their infrastructures and metastructures. Based on an analysis of the dynamics and paradigms that sustain these systems, it discusses how strategic devices can support the promotion of meaningful and sustainable change. It presents the arguments of Prospective Design and how this theory applies to methodologies such as Human- Centered Design (HCD), through an extension activity linked to an undergraduate course and an extension project using active methodologies at a public elementary school. Finally, it argues that, in the search for innovative solutions, one should not only address current existential problems, but also consider devices that transform the underlying structures, promoting long-term positive impact.
