DeviceOrientation Event Specification ( http://w3c.github.io/deviceorientation/spec-source-orientation.html) has been amended with the following changes: - added 'deviceorientationabsolute' event, - the already existing 'deviceorientation' event is now 'relative' by default. The idea is that 'deviceorientationabsolute' event can be used in Augmented Reality applications (when the direction of the magnetic north is important). While the 'deviceorientation' event would be suitable for Virtual Reality applications or games. In particular the reasons behind this change are the following: - compatibility of 'deviceorientation' with Safari on iOS (where it is 'relative' by default). - 'deviceorientation' does not require magnetometer anymore and is not distorted by potential external magnetic field. - usability of 'deviceorientation' for VR applications (e.g. no 'sensor drift' which occurred in the previous 'absolute' implementation) These changes have been implemented in Chrome for Android but are currently in 'experimental' state, i.e. not yet enabled by default. thanks, Tim
