Title:
REFERENCE COORDINATE SYSTEM DETERMINATION
Document Type and Number:
WIPO Patent Application WO/2014/070312
Kind Code:
A3
Abstract:
A method of determining a reference coordinate system includes: obtaining information indicative of a direction of gravity relative to a device; and converting an orientation of a device coordinate system using the direction of gravity relative to the device to produce the reference coordinate system. The method may also include setting an origin of the reference coordinate system and/or determining a scale value of the reference coordinate system. The method may also include refining the reference coordinate system.
