Navgate

Navgate is a navigational aid for the visually impaired. It is a haptic belt paired with a mobile app. 

It consists of three subsystems: positioning system, user interface and feedback to the user.

The Positioning System aims to locate the user's position by using BLE beacons, which will conceptually be placed throughout the airport’s infrastructure.
The User Interface will be a mobile application that takes in user’s input via Speech-to-Text and outputs audio information by Text-to-speech. A real-time database was also set up for the demo using Firebase to simulate retrieving flight information.

The feedback is in the form of a Haptic belt, which consists of
8 vibrating coins that correspond to a direction.

The function of the path-finding subsystem of the mobile application is to ensure that a path is mapped out from the start location to the destination and that the path found is the shortest and most efficient. Coded the A* Algorithm for the path finding function in the mobile app

Tested the BLE Beacons connections to the mobile application. Analysed the signal strength and robustness.

Refined skills in communication, teamwork, leadership. Learned Java and Android Studio.
