Basically, our project consists of two clocks. There is one for the teachers and one for the students.
The teacher's clock ticks when a student does not understand the explanation, does he understand it, more or less understands it, speaks or does not listen.
Our project focuses on SDG number 4.
Our device especially helps people who are embarrassed to ask or say that they did not understand, thus helping to make sure that students do not lose a knowledge due to embarrassment.
This device, being a watch, is particularly comfortable to wear.
