<p><P>PROBLEM TO BE SOLVED: To provide an information processing method, an information processing apparatus and a program for achieving efficient collaborative operations by efficiently specifying an object which should be targeted by a user who is trying to execute the cancellation of operations in a virtual space simultaneously accessible by a plurality of users. <P>SOLUTION: When an Undo button is selected, only operations related with objects OBJ1, OBJ2, and OBJ4 included in a View range VA1 are extracted as Undo candidate operations, and an operation related with an object OBJ3 positioned outside the View range VA1 is not extracted as the Undo candidate operation. Then, when the operation related with the object OBJ2 (in this case, a moving operation) is defined as the latest operation, the operation is canceled. That is, the Undo processing is executed to the object OBJ2, and the object OBJ2 is returned to the position before movement. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
