Tiago Oliveira, Manuel Freire · Interactive Learning Environments · 2025
Over 450 million people worldwide suffer from hearing loss, relying on over 200 sign languages for communication. Serious games offer a solution to teach sign language, bridging communication barriers. This systematic literature review examined 414 articles, identifying 42 serious games targeting 19 sign languages. Evaluations generally support their effectiveness in engaging and educating learners of all ages, both hearing impaired and non-impaired. This study aids game developers in selecting suitable technologies and approaches for developing and evaluating sign language teaching games. Serious games emerge as valuable tools in enhancing communication between hearing impaired and non-impaired individuals.
