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.

The tt2 system is highly adaptable for different use cases and can be customized to suit a multitude of venues with differing requirements. We have set up a standardized test that allow us to show the overall system accuracy for tt2. Depending on the chosen setup, the expected accuracy can differ in both directions.*

The system provides a position in real time, only using the computing power of the device. The system also provides a map which rotates so that it always “follows” the physical store. This removes any ambiguities in how the map is rotated for the end user, making for an easier navigation experience. The rotation signal is instant which makes the whole user experience feel responsive.
