Claim:
1. A virtual object control apparatus, the apparatus comprising: a processor configured to: receive detection information related to a user from a sensor; extract hand motion information related to hand motions of the user from the received detection information; determine whether the extracted hand motion information is valid based on confidence data; being expressed by a reciprocal of a variance of the extracted hand motion an average velocity of the extracted hand motion and a peak acceleration of the extracted hand motion; generate at least one of a posture event and a gesture event according to the extracted hand motion information, in response to the determination that the extracted hand motion information is valid; and output the generated event, wherein a virtual object displayed on a 3-dimensional graphic user interface (3D GUI) is controlled based on the generated event, wherein the processor is further configured to determine that the extracted hand motion information is valid if the confidence data is higher than a preset threshold value, the peak acceleration is greater than a threshold acceleration value, and the average velocity is greater than a threshold velocity value, wherein the virtual object is described by at least one scene representation method selected from binary formats for scenes (BIFS), light application scene representation (LASeR), and Widget.
