App Preventing People From Losing Themself in Crowd

See shield? Where was the X-ray Department? Where is the Austrian? There are clinics such as in Aachen and Frankfurt airport, the same a small town. Seeping effect guaranteed. Help comes from Dresden: Fraunhofer researchers have developed an app that navigate through aisles, corridors, rooms and floors. And how do you find Apple this idea?

Large trade fairs, airports, shopping malls, museums, hospitals and authorities a maze often similar to. Despite well-intentioned Guide and overview plans draws a lot of time in the country, until it finds its target. Researchers of the Fraunhofer Institute for Photonic Microsystems (IPMS) in Dresden have found a way to use your phone inside the building for the navigation. So far, GPS-based indoor classic navigation programs not work since walls and interfere with the satellite signal.

Software is based on Wi-Fi spots

The scientists use their navigation to the local wireless network Wi-Fi, which is becoming more widespread in buildings. Hospitals about had caught up strongly in recent years when Wi-Fi spots, explains IPMS researcher Christian Scheibner. “For example, there are more and more medical devices which are equipped with Wi-Fi radio and can be used for the Heesen.” The software of Fraunhofer researchers evaluates the signal strength of the Wi-Fi spots and can thus find the position of a Smartphone at 2 metres exactly.

Building plan appears on the Smartphone display

When starting the app the senseless user can target select – about examination rooms, patient rooms, canteens or toilets. As with navigation equipment in the car he sees the building plan two-dimensional from the bird perspective. Target and current position are marked with points.

The user starts the place point moves. Is the target off the screen, or on a different floor, arrows point the way. So he quickly reaches its destination. As long as he bangs on the constant gaze of the Smartphone with the nose against a wall.

And how do the software know how a building is constructed? It’s simple: The operator provides maps. Rescue plans also could use as a template, says Safi. “We can bring sharp and without annoying delay on each display any big card.”

Supposedly, it is also quite easy to integrate the positions and search algorithms in your own applications thanks to open interfaces. Well possible so that a lot of applications with the technology from Dresden in the future.

Speaking of large airports: for it is interested in the European satellite system Galileo: it aimed for example due to its high accuracy that all vehicles at an airport pass their place facts to a Central Office and so the control room know exactly where is just which tractor, bus, or gate stairs are. However: This works just outside.

Apple developed for indoor navigation app

Apple seems to experiment of indoor navigation with Smartphone app. Apparently, an app called indoor survey showed up on Sunday in the app store for a short time, the online magazine Apple Insider reported, citing the developer Steve Troughton-Smith. “Using points on a map in the survey application, you simply highlight your place within a place, while walking through”, it was reportedly said in the description of the app, which is now gone. “While you do it, measures the survey app radio frequencies and combines them with the sensor data of the iPhone.”
