The tt2 system is a revolutionary positioning system for mobile devices. Unlike all other positioning systems we have come across, tt2 is not dependent on any external signals.
The system requires that the device can provide accelerometer and gyroscope values. It can be deployed at any venue without setting up any infrastructure or doing venue-specific tuning. Together with our map-generation tool, a venue can be configured in minimal time. The only requirement to set up a new venue is to provide the tt2 system with a floorplan.
The tt2 system can be started in multiple ways. The most trivial start mode is using a fixed-point reference, such as a QR-code or a cradle storage location. Other possibilities are to start the system via external sources such as Wi-Fi-signals or GPS-signals together with a magnetometer.
