Claim:
1. A method for performing a process using a controller and a video display device including a processor, the method comprising: providing a reference structure having a known and constant spatial dimension; obtaining control data including at least one of image data captured by an image sensor in the controller of the known and constant spatial dimension of the reference structure and data determined by an analysis of the image data; calculating a first distance representative of a real space distance between the controller and the reference structure; defining an effective range as between a first distance from the reference structure to a second distance from the reference structure, wherein the effective range is defined to include the calculated first distance between the controller and the reference structure; calculating an effective range position representing a position of the controller within the effective range using the defined effective range and a calculated second distance representative of a real space distance between the controller and the reference structure; performing a process in the virtual world through an operation using data representative of the effective range position data, and displaying the virtual world after performing the process.
