Disclosed is an apparatus and method for classifying a motion state of a mobile device comprising: determining a first motion state associated with a highest probability value and with a first confidence level greater than a first threshold; entering the first motion state; while the first motion state is active, determining a second motion state associated with a highest probability value and with a second confidence level greater than the first threshold, the second motion state being different from the first motion state; determining whether the second motion state is to be entered; and in response to determining that the second motion state is to be entered, entering the second motion state.

Smartphone motion classifier

Systems, apparatus and methods for estimating a mass of an object by a mobile device are presented. The mobile device, which may be a smartphone, vibrates the mobile device both unloaded (without an object) and loaded (with an object) while measuring the unloaded and loaded vibrations. Next, the mobile device compares the unloaded and loaded vibrations and determines the mass of the object from the comparison.
