<p>PURPOSE:To naturally transfer and receive the right of device operation by displaying by mark a position by a coordinate indicating means on a display screen when the coordinate indicating means is made to come into contact or to approache on an inputting board during inputting of a coordinate position by plural coordinate indicating means. CONSTITUTION:Plural coordinate positions for the input board 12 by plural coordinate indicating means 13, 14 for indicating coordinate positions are indicated respectively and input operation for inputting the coordinate positions indicated by the means 13, 14 is performed by the input board 12. When plural coordinate indicating means 13, 14 come into contact or approach on the input board 12, a coordinate position detecting means 15 extracts the coordinate position data of the means 13, 14 and a coordinate conversion means 16 converts the coordinate position data extracted by the means 15 into one coordinate position data. A mark display means 11 displays a mark 18 on a display position corresponding to the coordinate position data converted by the means 16 on the screen of the device 11. Consequently the cursor operation right can be clearly and naturally transferred between plural persons.</p> |
