Support for visually impaired people to improve movement.
The GMark application is designed as a support for visually impaired people to move around and find themselves in space. GMark tags are located in various places such as offices, service premises, bus stops, and they advertise their presence via the BLE (Bluetooth Low Energy) protocol. The application detects such tags and reads information about them from the server. When the application finds the tag, it notifies the user and allows the user to run the tag if it is the active version. The active marker can play a melody / sound and generate a light signal
