In this project, four partners from three European countries intend to develop a new type of visual teaching material in the subject of mathematics for deaf students between 10-12 years.The unique thing for deaf students is that they need to get their education in their native language, the sign language, which is a visual language. Sign languages are different all over the world just like spoken languages. That is why the project includes Turkish Sign Language, Norwegian Sign Language and Swedish Sign Language.This project will produce a teaching material, in the sign languages of three different countries, in the subject of geometry where we use AR (Augmented Reality). AR is a technology that will enhance the comprehensibility of our deaf students, but which will equally work on other secondary target groups. The end product of this project will be able to be used in AR glasses and / or tablets or mobile phones. We will place both sign language content in the form of video as well as geometric graphics in an educational layer on these units.Together we will produce the script with our mathematics teachers and special pedagogues from the three countries. After translations into each different sign language it will be recorded with a deaf actor from each country in the greenscreen studio the Swedish partner possess. The sign language videos will then be merged together with geometry graphics into AR by our Turkish partner. The combined effort of all partners and the final result of the educational material of geometry in AR, will amaze the end users which opinions will be researched and evaluated by Örebro University. In the long term, this AR material, will probably set the standard become a whole new media of distribution of educational material for the deaf pupils.
