With ongoing advancements in virtual reality and gamification, researchers have started exploring their application in sign language learning, aiming at enhancing communication between hearing individuals and the deaf community. This study compares the impact of 2D and 3D games on American Sign Language (ASL) learning, using questionnaires to assess user experience. Results show that 3D games enhance engagement, attractiveness, usability, and efficiency, although user performance remains similar in both environments. The findings suggest the potential of 3D game-based approaches to improve ASL learning experiences while also identifying areas for enhancing their dependability and clarity.
