Resumo(s)
Blind individuals continue to face challenges in accessing information about their physical activity due to the predominance of visual interfaces in monitoring systems. Although accessible solutions exist, they still do not offer the same usability and autonomy available to sighted users. This dissertation investigates how auditory feedback can support fast, low-cognitive-effort interactions when accessing physical activity data, with the goal of removing barriers and enabling new experiences. The research was structured into two complementary studies. Study 1 consisted of conducting semi-structured interviews with blind or visually impaired users, aiming to understand their physical activity practices, their relationships with monitoring technologies, and their preferences regarding fast and integrated auditory representations. The analysis revealed concerns about cognitive load, privacy, and contextual appropriateness, and highlighted the importance of using brief, simple, and emotionally suitable sounds. Study 2 further explored these findings by inviting participants to imagine, through use-case scenarios, how such an auditory/haptic system could function in their daily lives. These conceptual simulations made it possible to explore expectations, benefits, and concerns associated with long-term use. Participants expressed a preference for motivating, customizable feedback that is sensitive to social context, reinforcing the need to avoid intrusiveness, excessive repetition, and moments when the system might feel absent. Together, the studies identify opportunities and challenges in designing auditory feedback for physical activity monitoring. The dissertation proposes essential qualities and guiding principles for more meaningful and contextually appropriate sonic experiences for blind individuals. The main contribution lies in adapting and expanding the concept of glanceability to a sonic dimension, demonstrating that fast, low-effort interactions can be effectively translated from the visual domain to the auditory one and, ultimately, promote greater inclusion.
