Information technologies have been growing and developing at a rapid pace. With the creation of 3D virtual world platforms came the possibility of creating a metaphor for the real world.

This study presents the current scenario of the Microsoft Kinect human-computer interface and introduces it as the main means of interaction between man and machine applied in a 3D virtual world.
