<P>PROBLEM TO BE SOLVED: To improve operability on controlling a projected image using a pointing device. <P>SOLUTION: When a mouse 130A is moved to the right side in a horizontal direction (X axis direction) by a distance L and more and then moved to the left side by the distance L and more within prescribed time T, a computer 120A detects the operation as specific operation. The computer 120A adds flag data (operation command) indicating whether the specific operation is executed or not to mouse data in operation information of the mouse 130A. When a flag indicating the execution of the specific operation is set in an operation command 153', a projector 100 changes a display state of a cursor 111A (in some cases, cursors 111B to 111D) to a specific state. <P>COPYRIGHT: (C)2009,JPO&INPIT |
