Claim 0:
1. A method for detecting manual use of a mobile phone by a driver of a vehicle, the the method comprising:
a. receiving contemporaneous Earth-frame-referenced heading and speed data pertaining to a vehicle;
b. deriving, based on the contemporaneous Earth-frame-referenced heading and speed data, to the exclusion of any accelerometer data, an incremental heading change, a sign associated with the incremental heading change that is one of positive or negative, and a calculated nominal radial acceleration based on the contemporaneous Earth-frame-referenced heading and speed data;
c. calculating a signed offset between the calculated nominal radial acceleration and a measured actual radial acceleration of the mobile phone, the signed offset bearing the sign associated with the incremental heading change; and
d. determining manual use by the driver, as distinct from any passenger, on the basis of at least the signed offset between the measured actual radial acceleration of the mobile phone relative to the calculated nominal radial acceleration.
