Putter path detection and analysis

A method for analyzing a putting stroke using a stroke sensor assembly including a processor, a memory communicating with the processor, and an accelerometer, the method comprising:

• determining a preferred putting path based on successful putts executed by a user, the preferred putting path being unique to the user, and storing the preferred putting path in the memory;
• measuring characteristics of a putting stroke with the accelerometer;
• comparing, with the processor, the characteristics of the putting stroke with the preferred putting path;
• and
• generating an output indicative of the comparison.

A putting stroke sensor assembly cooperable with a putter head, the putting stroke sensor assembly comprising:

• a processor;
• a memory communicating with the processor;
• and
• an accelerometer communicating with the processor, the accelerometer being configured to measure characteristics of a putting stroke,
• wherein the processor is programmed to operate in a learning mode in which the processor interactively communicates with a user to measure a preferred putting path that is unique to the user based on successful putts executed by the user, the memory storing the preferred putting path, and wherein the processor is further programmed to compare the characteristics of the putting stroke with the preferred putting path and to generate an output indicative of the comparison.
