What kinds of location based augmented reality exist?

Location based Augmented Reality shows Augmented Reality content that is attached to a specific location, which can be outdoor or indoor.

Outdoor location based Augmented Reality

Outdoor location based Augmented Reality shows Augmented Reality content triggered by specific GPS location.

In order for GPS location Augmented Reality apps to work a user’s phone needs to have GPS option turned on. GPS accuracy is affected by a number of factors, including satellite positions, noise in the radio signal, atmospheric conditions and  natural barriers to the signal. Noise can create an error between 1 to 10 meters and results from static or interference from something near the receiver or something on the same frequency. Objects such as mountains or buildings between the satellite and the receiver can also produce error, sometimes up to 30 meters. Therefore, much more accurate user position is shown when the user stands on an open field instead in a city surrounded by buildings.

Indoor location based Augmented Reality

GPS location is not really suitable for indoor usage since the use case quite often requires an accuracy of less than 10m. Therefore, we offer two different indoor location based Augmented Reality solutions.

Beacon (Bluetooth)

The position within a building can be determined through the use of Bluetooth Beacon (iBeacon). The use of Bluetooth Low Energy (BLE) technology enables the use of batteries for months, without having to resort to external power supplies. This means that temporary installations, such as exhibitions, can also be realized in unusual locations. The position can be identified inside enclosed buildings to within a few meters.

Smartphone sensors

The utilization of the internal sensors of a smart phone also plays an important role in indoor positioning and indoor navigation. Here a variety of sensors in a mobile device (smart phone) are used and evaluated: GSM, 3G/4G (LTE), magnetic fields, compass, air pressure, barometer, accelerometer and gyroscope. Positioning can be significantly improved through the unique combination of these technologies with the other options for navigation inside enclosed buildings.
