Fuzzy logic-based evaluation and feedback of exercise performance

A fitness system comprising:

• a camera-based sensor to detect image data of a user;
• one or more processors;
• and
• memory, storing instructions that, when executed by the one or more processors, perform operations comprising:
• generating a set of exercise rules based, at least in part, on personal information about the user;
• analyzing the image data detected by the camera-based sensor to produce one or more measurements representative of a muscle tension of the user;
• mapping the one or more measurements representative of the muscle tension to a set of fuzzy variables by a membership function;
• and
• generating an evaluation for the user based, at least in part, on i) the set of fuzzy variables and ii) the set of exercise rules.

A computer-implemented method comprising:

• generating a set of exercise rules based, at least in part, on personal information about a user;
• detecting, by a camera-based sensor, image data of the user;
• analyzing the image data to produce one or more measurements representative of a muscle tension of the user;
• mapping the one or more measurements representative of the muscle tension to a set of fuzzy variables by a membership function;
• and
• presenting, on a display, an evaluation for the user based, at least in part, on i) the set of fuzzy variables and ii) the set of exercise rules.
