Information processing apparatus and non-transitory computer readable medium

A non-transitory computer readable medium storing a program that causes a computer to execute information processing, the computer including a preparation device configured to prepare information on a posture of a body, an acting force meter configured to measure a first acting force that the body applies on a first object, a myoelectric potential meter configured to measure a myoelectric potential from a surface of the body, and a processor, the information processing comprising:

• acquiring the information on the posture prepared by the preparation device;
• acquiring information on the first acting force measured by the acting force meter;
• acquiring information on the myoelectric potential measured by the myoelectric potential meter;
• setting an initial value for a second acting force that the body applies to a second object other than the first object;
• estimating a muscle activity state of the body corresponding to the posture, the first acting force, and the second acting force;
• repeating updating the second acting force such that a difference between (i) a muscle activity state determined based on the myoelectric potential and (ii) the estimated activity state decreases;
• and
• presenting the second acting force when the difference is less than a predetermined threshold value.

An information processing apparatus comprising:

• preparation means for preparing information on a posture of a body;
• acting force means for measuring a first acting force that the body applies on a first object;
• myoelectric potential means for measuring a myoelectric potential from a surface of the body;
• and
• means for
• acquiring the information on the posture prepared by the preparation means;
• acquiring information on the first acting force measured by the acting force means;
• acquiring information on the myoelectric potential measured by the myoelectric potential means;
