Patent ID: 7010756

Claim:
A display operating system comprising: a detecting section for detecting a plurality of unique positions of an operating body on an operating plane; an inputting section for inputting one of a position detection signal and a determined candidate selection signal, the inputting section being provided with the detecting section, and the position detection signal corresponding to only one of said unique positions of the operating body on the operating plane detected by the detecting section, and the determined candidate selection signal corresponding to only one of said unique positions of the operating body on the operating plane detected by the detecting section; a monitoring section for displaying a plurality of groups of selection elements displayed on a screen provided thereat wherein a total number of displayed selection elements is greater than a total number of position detection signals that can be generated by said inputting section; and a controlling section for controlling such that, of the plurality of groups of selection elements displayed on the screen of the monitoring section, at least one group of selection elements at a position corresponding to the position of the operating body on the operating plane is set to a selectable state on the basis of the received position detection signal, and, of the at least one group of selection elements in the selectable state, one selection element at a position corresponding to the position of the operating body on the operating plane is set to a determined candidate on the basis of the determined candidate selection signal, wherein, if, between a time of reception of the position detection signal and a time of reception of the determined candidate selection signal, the controlling section receives a different position detection signal satisfying a specified condition, a different group of selection elements, from the first selected group of selection element, is set to the selectable state by the controlling section, wherein the different group of selection elements corresponds to the new position of the operating body on the operating plane, such that said inputting section is capable of sequentially generating either a position detection signal and a determined candidate selection signal, or first and second position detection signals.
