Operation system and operation method

An operation system comprising:

• a circuitry configured to determine a predicted value of an operator motion after a predetermined prediction latency from a current time based on a bio-signal using a prescribed machine learning model, where the bio-signal is captured from the operator;
• and
• a controller configured to control a motion of a robot based on the predicted value,
• wherein the circuitry is configured to:
• capture an image representing the robot and its surrounding,
• estimate a second motion of the robot based at least on the image,
• produce a first motion signal for the first motion and a second motion signal motion for the second motion, and
• determine the necessity of the first motion and the second motion with reference to selection data, the selection data indicating whether to select the first motion and the second motion, and the selection data preset in the circuitry, and
• control the first motion and the second motion based on the necessity,
• wherein the second motion includes:
• a motion of which a possibility of being intended by the operator is higher than those of other motions based on the image,
• a motion that is more delicate than the first motion,
• a motion of an individual finger, and
• a fine adjustment of one or both of a position or a direction of a hand part.
