Abstract Communication barriers between Deaf patients and healthcare professionals remain a critical challenge in ensuring equitable medical care. This study examines the application of immersive technologies to facilitate anamnesis processes in Brazilian Sign Language (Libras), to improve accessibility and autonomy for Deaf individuals in medical settings. We conducted a systematic mapping of immersive applications designed for the Deaf community, which informed the development of two augmented reality–based solutions: one tailored for magnetic resonance imaging anamnesis and another for pupillometry examinations. Both applications enable interaction through Libras, hand gestures, and touch inputs, avoiding reliance on spoken or written language. To validate these tools, we carried out a usability evaluation with 27 Deaf participants using SUS-Libras, a culturally adapted version of the System Usability Scale. Results indicated an average score of approximately 55 points, classified as “OK” on the adjective rating scale, suggesting a satisfactory though improvable usability perception. No significant differences were found between the two applications, and demographic factors such as age, gender, education, and exposure time to Libras showed no predictive effect on usability outcomes. The research contributes to inclusive design practices and provides a foundation for future studies that extend immersive technologies to other medical scenarios.
