Claim 4:
5. A wearable ergonomics improvement system comprising:
an encoder system to couple to a limb of a body, the encoder system to generate first outputs in response to movement of the limb relative to the body to determine a position of the limb relative to the body, the encoder system including:
a first encoder assembly to generate first ones of the first outputs in response to movement of a shoulder to determine a first position of the shoulder relative to the body, wherein the first encoder assembly is a first string encoder assembly including:
a first string encoder;
a first anchor;
a first string having a first end coupled to the first string encoder and a second end attached to the body via the first anchor, the first string to extend at least partially across a shoulder joint of the body;
a second string encoder;
a second anchor; and
a second string having a first end coupled to the second string encoder and a second end coupled to the body via the second anchor, the second string to extend across at least partially across the shoulder joint of the body, and the second string to cross the first string;

a second encoder assembly to generate second ones of the first outputs in response to movement of an elbow to detect a second position of the elbow relative to the body; and
a third encoder assembly to generate third ones of the first outputs in response to movement of a hand to detect a position of the hand relative to the body;

a load sensor to generate a second output representative of a load carried by the body; and
a position sensor to generate a third output representative of a position of a right foot of the body relative to a position of a left foot of the body.
