Detection of user activities by a portable device

At least one non-transitory computer-readable medium comprising computer-executable instructions that, when executed by at least one processor associated with a portable consumer device, configure the at least one processor to:

• receive, from at least one inertial sensor, measurements data associated with one of (i) movement of the portable consumer device or (ii) orientation of the portable consumer device;
• receive, from at least one context sensor, data associated with an external environment of the portable consumer device;
• compare an amplitude of the data to an amplitude threshold;
• determine, based at least in part on the received measurements data, the received environment data, and the comparison of the amplitude of the data to the amplitude threshold, a user activity;
• compare the determined user activity to a desired user activity;
• and
• display user feedback on a display based at least in part on the comparison.

A computer-implemented method comprising:

• executing, by a portable consumer device comprising one or more computer processors, at least one application configured for:
• outputting a direction associated with a desired user activity;
• receiving, from at least one inertial sensor, measurements data associated with one of (i) movement of the portable consumer device or (ii) orientation of the portable consumer device;
• receiving, from at least one context sensor, data associated with an external environment of the portable consumer device;
• comparing an amplitude of the data to an amplitude threshold;
• determining, based at least in part upon the received measurements data, the comparison of the amplitude of the data to the amplitude threshold, and received environment data, a user activity;
• comparing the determined user activity to the desired user activity;
• and
• displaying user feedback on a display based at least in part on the comparison.
