Sign language learning toy

This chest is a tool designed by students of Industrial Design Engineering and Product Development at the University of Zaragoza to facilitate and promote the learning of Spanish Sign Language through a trial-and-error method.

 The project was developed based on the case of Eiden, a six-year-old child with hearing impairment who was experiencing difficulties learning sign language. Thanks to the collaboration of his teachers, we were able to analyze the key aspects that needed improvement in the classroom in order to enhance his interaction with classmates.

The device operates in an intuitive and dynamic way: it includes a screen that displays videos of different signs that the user must identify. To answer, the child searches among several physical coins for the image corresponding to the displayed sign and inserts that coin into a slot. If the answer is correct, the system moves on to the next sign; if incorrect, the child has two more attempts. The vocabulary is organized in a booklet divided into seven thematic categories, each associated with a specific color to make identification easier: nature, people, places, objects, emotions, actions, and abstract concepts.

The toy aims to teach children with or without hearing impairments, using play as a tool to learn sign language, break down communication barriers, and help create a more inclusive society for everyone.

We are especially proud of how our design promotes a refill culture, encouraging people to shop locally in bulk stores and support independent businesses that share our values of sustainability and waste reduction.
