Three students of Athens College honoured Greece by winning first place in the world competition of Artificial Intelligence WAICY.

Creating the navigAid application, an application-aid for visually impaired people, a three-member group of students from Athens College won the top distinction in the WAICY (World Artificial Intelligence Competition for Youth).

Chrysa Vamvaka, Christiana Georgakopoulou and Amalia Christina Toutziaridi, led by IT professor Andreas Karabela, inspired and created navigAid.

The app aims to enhance the accessibility and autonomy of visually impaired people in the natural and structured environment.

The navigAid application is designed based on specifications for the operating environment of smartphone-type mobile phones and with the help of Artificial Intelligence, supports and simplifies the daily life of people with partial or total vision loss.

The navigAid constantly provides information via voice messages about the exact location of stores (pharmacies, kiosks, supermarkets, etc.), the colour of traffic lights, street names, the value of banknotes and many other useful information.

After intensive preparation for the collection and classification of information, the organisation of the database, the teaching of the Machine Learning model, the writing of the code on which the application is based, and so on, the three students were able to present a perfectly functional application.
