Multi-sensor system and method to deter obsessive compulsive behavior

A method for providing an alert responsive to the relative proximity between one or more of a user's appendages, the method comprising the steps of:

• attaching at least one sensor subsystem to a user's first appendage, each said sensor subsystem comprising at least two sensors in relative spaced relation;
• moving said first appendage in a pre-determined calibration motion pattern;
• adjusting the sensitivity of said sensor subsystems responsive to said moving step, such that the sensor subsystems negate the affect of the earth's magnetic field on said sensor subsystems;
• attaching at least one trigger subsystem to a second appendage of the user;
• monitoring the proximity of all said trigger subsystems to all said sensor subsystems;
• and
• emitting an alert perceptible to the human senses when the distance between any said trigger subsystem is closer to any said sensor than a preset threshold distance.

A wearable proximity alert system, comprising:

• at least one magnet subsystem configured to be worn by a user on a first portion of the user's body;
• and
• at least one sensor subsystem configured to be worn by the user on a second portion of said user's body, with each said sensor subsystem in spaced relation to other said sensor subsystems worn by the user, each said sensor subsystem comprising:
• at least two sensor systems in relative spaced relation for detecting when one said magnet subsystem is less than a threshold distance from said sensor system;
• a calibration system for comparing the magnetic field detected by one said sensor system and the magnetic field detected by the other said sensor system;
• and
• an output system for generating an alert perceptible to the human senses when one said sensor system detects a magnetic field that is stronger than a threshold strength and also stronger than a magnetic field detected by another said sensor system.
