description This study aims to analyse the users’ perceptions about a 3D digital artifacts prototype for teaching the fingerspelling alphabet of Brazilian Sign Language (LIBRAS). For this purpose, a high-fidelity prototype was developed with a non-programming method, and a usability test was conducted using a structured questionnaire with 31 participants, including Deaf and hearing people. Most users (96.7%) rated the learning experience with the tool as positive, with 67.7% rating the experience as "good", 12.9% as "very good", and 16.1% as "excellent". Comparing the evaluation between Deaf and hearing people showed that both target groups mostly rated it positively. However, most hearing people rated it "good," while the majority of the Deaf rated it as "excellent" (29%) or "outstanding" (14%) compared to 13% and 12%, respectively, among the hearing. In summary, considering the variables presented, the experience was well rated and did not encounter solid obstacles or resistance.
