A method of determining the location of a device on the body of a user carrying it, comprising determining a mathematical representation of a transformation between a device reference frame and an earth reference frame at the device; receiving information from a sensor arrangement of the device capable of measuring device movement while the user is walking, and transforming information from the sensor arrangement, using said mathematical representation, into the earth reference frame at the device; and performing statistical analysis on at least one component of the information from the sensor arrangement obtained in the transformation to identify one or more features corresponding to a specific location of the device. Also provided is a method of determining the orientation of a user's body relative to a reference frame, using a device carried by a user. The method comprising determining a location of a device on the body of a user carrying it, and selecting a method out of a plurality of methods for determining the orientation of the user relative to the reference frame based on the determined location of the device. |
