This is the ACM IMX paper authored by Patricia de Torres, Tamás Bukits, Joseba Ruiz, Iker Burguera, Mikel Zorrilla, and Sergio Cabrero. It serves as an in-depth exploration of how former inmates and other demographics subjectively perceive personal items. By anchoring the research in the documentation gathered on 1 December 2025 at LICEU, the paper provides a detailed look at these unique subjective perceptions.
