TUET (Toys & games Usability Evaluation Tool) is a method of analysis to evaluate play materials by considering the physical characteristics that are appropriate for children with hearing, visual, or upper-limb motor impairments.

Based on Universal Design principles, this unique tool helps children with the widest range of abilities to play for the sake of play with easily accessible and usable toys and games. A quick analysis with TUET makes the identification of such play materials possible.

What is TUET for?

TUET is designed for toy companies, for education and rehabilitation professionals, toy librarians, teachers and parents to help them design, select and adapt toys and games to the needs of all children, including those with hearing, visual or motor impairments.

To design inclusive toys and games

To identify and select inclusive toys and games

To understand the needs of children with disabilities

What does TUET evaluate?

It evaluates the usability and accesibility of toys and games considering three impairments: Hearing, Visual, and Upper-limb Motor.

How it works

After reading the detailed instructions on how to use the tool, there are three steps:


Define the purpose and intended user of the toy/game


Indicate the type and level of impairment of the intended user


Answer each question on the tables, calculate results and evaluate the toy/game
