Smartphone motion classifier

A mobile device comprising:

• a memory;
• and
• a processor coupled to the memory, the processor to:
• determine a first motion state associated with a highest probability value and with a first confidence level,
• enter the first motion state,
• while the first motion state is active, determine a second motion state associated with a highest probability value and with a second confidence level, the second motion state being different from the first motion state, wherein a confidence level of a motion state, associated with a highest probability value, is greater than a first threshold, and is determined based on a difference between the highest probability value and a probability value associated with a motion state with a second highest probability value,
• determine whether the second motion state is to be entered, and
• in response to determining that the second motion state is to be entered, enter the second motion state.

A mobile device comprising:

• means for determining a first motion state associated with a highest probability value and with a first confidence level;
• means for entering the first motion state;
• means for while the first motion state is active, determining a second motion state associated with a highest probability value and with a second confidence level, the second motion state being different from the first motion state, wherein a confidence level of a motion state, associated with a highest probability value, is greater than a first threshold, and is determined based on a difference between the highest probability value and a probability value associated with a motion state with a second highest probability value;
• means for determining whether the second motion state is to be entered;
• and
• means for in response to determining that the second motion state is to be entered, entering the second motion state.

A non-transitory computer-readable medium comprising code which, when executed by a processor of a mobile device, causes the processor to perform a function comprising:

• determining a first motion state associated with a highest probability value and with a first confidence level;
• 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, the second motion state being different from the first motion state, wherein a confidence level of a motion state, associated with a highest probability value, is greater than a first threshold, and is determined based on a difference between the highest probability value and a probability value associated with a motion state with a second highest probability value;
• 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.
