Bridge / IoT chalk holder and projector


It would be right to offer educational opportunities to children who can not go to school for any reason. 'Bridge' presents the solution through the electronic chalk holder and the standing projector. The electronic chalk holder has a built in microphone and accelerometers to record the teacher's voice and writing coordinates. These data is immediately sent to the cloud server and broadcast through children's standing projectors at home. 'Bridge' will become a connection between school and home for equal education to everyone.
