Smart Navigator

Do you know that the error in determining a person’s position in space via GPS reaches 50 meters? We know! Our developers have managed to reduce this error. We have created a mobile application "Smart Navigator" which allows determining the user's location with an accuracy of the angle in the room. It is based on the trilateration method using iBeacon. The name of the client, the project goals, and details are all under the NDA. But we can share with you the implemented technical features.

Our task was to create a system that would adapt to the location and habits of the house owner. To localize the location, we made a special version of the Bluetooth beacons, created a mathematical model of the user's environment, and several mobile applications for configuration and use of the system. The server was integrated with the existing real-time home control solution which allowed to provide users with exactly those management objects that were around them at the moment.

In this project we did:

Map processing

We decided to store the data about the premises, borders, and objects indoors in SVG format. Then, the map was uploaded to the server which automatically recognized the premises and objects. The server allowed providing the map with additional data: the name of the premises, the texture for the objects, the functions possessed by the objects, the access rights for a specific user and much more. As a result, after processing the map, the app knew everything about everything including the location of the radio beacons.

Animation and perspective

Since it was not only a room but a whole building, we have implemented a convenient zoom and beautiful animation to display a map of all floors premises in perspective.
For indoor navigation, a special version of the radio beacon was developed which could operate in both iBeacon mode and BLE mode to increase the frequency of transmitted signals. The combination of data gave the best result for determining the location.

Real-time object state

Another interesting technical challenge was keeping the map up to date. Turned off lights or opened window—everything is automatically updated in the app.
For this:
— the server was integrated with hardware data sources,
— we have developed a server interaction protocol through sockets with a mobile application in real time.
In addition to all the technical achievements of the project, we have gained unique experience in developing complex administrative tools on Ajax technologies as well as in creating a data privacy system.
