Location Based channels

Location Based channels show points of interest (POIs) in the surrounding of the user. The user can hold his/her phone up and look around to see virtual objects floating at the position of a POI. Those virtual objects can be individualized with text, thumbnails or can be animated and static 3D objects. Each POI can be linked with images, sounds, videos or websites. Also an easy integration of navigational hints, websites, email addresses or phones numbers related to a POI can be done.

Each device supporting junaio has a GPS sensor and a compass, so junaio knows, where a user is at and which direction he or she is looking.

When you create a channel with location-based Points of Interest (POIs), you will provide a GPS position for each POI. This position consists of a latitude and longitude value, as well as altitude (Note: Altitude is currently mostly ignored, since the GPS sensors are very inaccurate on altitude values).

Since junaio now knows where the user is at and where the POI is placed in the world, we can render certain virtual information "exactly" where it is in the real world as well. 

A note on accuracy

Currently, devices are somewhat inaccurate. GPS is accurate to about 10-15m in a perfect case, and as bad as 500m indoors. We are constantly working on using our experience to also improve this accuracy in all environments (e.g. Augmented City / SLAM).
