<p><P>PROBLEM TO BE SOLVED: To provide an information processor in which respective users of a coordinate input device connected to the information processor and capable of outputting a plurality of coordinates can operate a shared screen in parallel, and to provide its controlling method. <P>SOLUTION: A shared screen display device 101 for displaying a shared screen which are shared by a plurality of users is connected to a plural coordinates input device 102 for detecting coordinate values indicated by using a plurality of coordinate pointing tools and generating a plurality of coordinate data. On the basis of the positions and anterior/posterior relation of windows of a plurality of applications displayed on the display device 101 and coordinate data inputted from the coordinate input device 10, an input distribution part 106 determines whether the coordinate data are to be supplied to the applications or control right is acquired and an event is to be issued to an operating system 108. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
