ELIA - Express Language in Actions: Learning Tool for children with hearing impairments

Background:

Sign language is crucial for communication and early development in deaf children. In Switzerland, approximately 200 children per year are affected by deafness. Without early language acquisition, children often experience difficulties in language development, lower academic performance and an increased risk of social exclusion. Early learning can lower these risks, promote social integration and improve academic success. Children benefit particularly when they have access to high-quality sign language models. Despite the proven importance of early sign language, there are very few digital, age-appropriate learning resources for children under five. This highlights a significant research gap precisely during the developmental phase in which the linguistic and cognitive foundation for later literacy are establishes.

Methods:

The project follows a multi-stage, interdisciplinary approach. First, a literature review is conducted on early learning in deaf children and the role of caregivers. Based on this, the interdisciplinary team develops an interview guide and conducts interviews with parents of deaf children as well as professionals in special education and speech therapy. The findings from literature review and interviews feed into the development of a learning tool prototype with both digital and analogue elements, which is then tested by the experts. The project brings together expertise from the Institute of Health Sciences, the Institute of Interactive Informatics and the Bachelor of Science Occupational Therapy program.

Outcomes and Impact:

The project involves developing a prototype of a playful learning tool featuring 1 – 2 signs, designed to help deaf preschool children get started with sign language. Through stories and tasks, additional signs are gradually introduced. The approach provides new insights into how digital and playful methods can support early language acquisition. The results contribute to the development of suitable learning materials and aim to strengthen the children’s language and communication skills. Parents, siblings and friends can also use the tool to learn together with de children. This helps to integrate the sign language into everyday life and promotes social participation. In addition, the project aims to raise societal awareness of sign language, reduce barriers and foster inclusion and participation for deaf children.
