<p><P>PROBLEM TO BE SOLVED: To provide an operation state determination device which can provide more appropriate operation support to a user by presenting a target function with high presumption accuracy to the user by discriminating a history of operations performed randomly and deleting them even if the user issues an operation support request after the user performs the operations at random. <P>SOLUTION: The operation state determination device is provided with an operation load calculation unit 106 which calculates a user operation load upon the execution of user's selection operation to an instrument by using the current selection operation and the other selection operation which is contained in the history of the selection operation performed for executing the function of the instrument by the user and precedes the current selection operation, and an unthought operation determination unit 107 by which as the operation load of the user calculated at the operation load calculation unit becomes smaller, the selection operation is determined as a more randomly-performed operation. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
