The Global Positioning System makes a great job of locating users and devices in real time with high accuracy. This function of smartphones and tablets can be really useful especially when you are somewhere outdoors in the unfamiliar place. However, GPS doesn’t work in the indoors environment- the satellites signals are not able to penetrate anything else bigger that a car roof. That is why today much prominence is given to the new ways of guiding people who are indoors. However, the indoor navigation is necessary when you are situated in a large building and want to visit specific place like certain café in the airport or certain picture in the museum.
As an alternative to the GPS developers have decided to use a Wi-Fi and have created apps that are able to locate the user with help of trilateration- the process of measuring distances between the user and three access points. However, the apps are not as accurate as GPS because they don’t show but predict what room you are in. So there apps require a lot more attention from the developers because their work is not ideal at the moment.
It is a company that helps other businesses to develop apps focused on location-aware technologies. Their the most well-known product known as the Meridian Editor helps to edit and manage location based applications. Many big well-known museums, hospitals, stadiums and airports use this editor for creation of their own navigation applications. Four tools created by the company (the AppMaker, NavKit, BluDotKit and ZoneKit) help their clients to create precise and successful apps.
it is the first app created with help of the Meridian Editor. The app for the American Museum of Natural History helps visitors to find certain exhibition as well as current location of the user, create custom tours, find exhibits, shops of the museum and restrooms and exits.
The technology used by Infsoft is able to find the location of the user inside the building with an accuracy of a few meters using data from the 3G, compass, Wi-Fi, accelerometer etc. of the device. And when the person leaves the building, the app will be connected to the GPS.
