LOCATIONAR

Simple Location based Argumented Reality library, based on the WebRTC, Geolocation, DeviceOrientation and AmbientLightSensor

Online Samples:

1. Use Chrome
2. goto the Compass example and see if it's working [camera is working, north in the right direction]
3. goto the Location example and you should see a red cube 10 m in the direction of North
4. If you don't see the cube or want to change the position click "InfoPanel" and then you can press the button GetPosition to set the position of the cube to your current position and offset it with the +10N, +10W,... buttons Here you can also see the raw sensor data

Problems/Limentations

• missing compass accurcy[can't find exact numbers, but up to +/- 10° on good devices, on some devices completely unuseable]
• camera fov[different phones have different fov's and if the difference between the camera fov and the set fov is to big, the mapping for non-centered, far away objects will be distorted]
• gps accurcy[can be a problem if the object is nearer than 20 meters]
• to use the light ambient light sensor, you need to set the chrome flag #enable-generic-sensor-extra-classes to enabled
