Grenoble: Movea, a French indoor navigation systems provider, has announced two successful trials of its real time indoor navigation mobile app. The company tested its solution in Paris-Gâre de Lyon in France and at the University Station in Seoul, South Korea. The solution works best in buildings with maps and blueprints.
Movea’s mobile app asks for the user’s height to estimate the step length. When the user moves, the accelerometer in the phone registers the step. A magnetometer is used as a compass to know which way the user is facing. Over time, it figures out the trajectory and then uses it for user’s location.”Map matching” or using blueprints for buildings plays a vital role. The app uses the building’s blueprint to match user’s location. If it senses a change in the pressure, it will figure out that the user is going up the elevator. The pressure change is measured by a pressure sensor, which is present in some Samsung devices. Movea partnered with the SNCF, France’s national railway company, and a platform service provider SK planet, a wholly owned subsidiary of SK telecom, South Korea’s largest mobile network operator, to test the indoor navigation solution in the real world. In both the demos, users successfully navigated through two busy train stations that serve thousands of commuters on a daily basis.
