<p>PROBLEM TO BE SOLVED: To scroll an object to be observed which is displayed on a displaying medium such as a display without giving an observer a visual load. SOLUTION: Data S read from media 2 are shown on a display 1 and the displayed position is set as a reference position. The movement of a display device 7 is detected by a sensor 4, and a scroll operating part 6 calculates the scroll quantity of an object to be observed which is shown on the display 1 and scrolls based on the detected scroll quantity. The scroll is fixed at the point of time when the sensor 4 is turned off, and an observer moves the display device 7 to a position where the observer easily sees it and observes display contents shown on the display 1. When scroll is performed again, the sensor 4 is turned on, the display device 7 is moved and the object to be observed is scrolled.</p> |
