Systems, methods, and articles of manufacture to measure and recommend lie angle

A system for detecting and characterizing a position of a golf club, comprising:

• a golf club having a shaft;
• a connection mechanism coupled to the shaft and configured to hold a portable electronic device, the portable electronic device comprising:
• an application display;
• a plurality of sensor components including a gyroscope and an accelerometer;
• and
• a processor in operable communication with a memory including instructions defining a process executable by the processor, the process, when executed, being operable to:
• issue an indication for a user to line up the golf club in an address position;
• continuously compute a stream of lie angles based on actual lie angle data from the accelerometer as the user holds the golf club;
• dynamically calculate a standard deviation of the stream of lie angles;
• calibrate the gyroscope to detect movement of the golf club;
• numerically define a sensitivity threshold, corresponding to an upper limit of the standard deviation of the stream of lie angles that indicates when the golf club is in the address position;
• trigger a first countdown, once the standard deviation of the stream of lie angles drops below the sensitivity threshold;
• activate a lock-in period, after the first countdown expires without the standard deviation of the stream of lie angles exceeding the sensitivity threshold;
• wherein the accelerometer measures a locked-in lie angle after the lock-in period expires;
• and
• wherein the locked-in lie angle corresponds to a color code, the color code being predetermined to be associated with one or more suggested golf clubs approximately calibrated to the locked-in lie angle.
