PROBLEM TO BE SOLVED: To prevent erroneous selection and convenience reduction by dynamically determining the response time of operating button selection and to display a lot of operating buttons without reducing the display of documents. SOLUTION: The sight line of a worker watching a document and a monitor displaying the operating button in a semi-transmission state on the document is detected and recorded by a sight line recorder 1, work performed by the worker is discriminated from this detected sight line information by a work discriminating part 2, the reaction time of the operating button is dynamically determined based on this discriminated work by a reaction time determining part 3, the state just under the selection of the operating button is detected based on the information by a selection detecting part 4, when this detected state under the selecting of the operating button is continued longer than the reaction time, an operation executing part 5 discriminates that operating button is selected, and processing allocated to this operating button is executed. |
