Abstract
An intention estimation and operation assistance system for estimating an operator'"'"'s intention and providing assistance to operation of a machine. Reference data, such as the operation of a plurality of hypothetical operators, is provided for comparison with the operation of a real operator, to determine an estimated intention of the operator. The estimated operator is utilized to alter the operation of the machine, to provide a safer and/or smoother operation experience in operating the machine.
