A method in a video gaming system including a processor, a memory and a sensor system for capturing body motion is described. In one embodiment, the body motion can be associated with a person pretending to hit or launch an object, such as an object used in a sporting activity. In general, body motion can be associated with any activity involving similar body motions that are repeated during the activity. In a video game generated by the video gaming system, a consistency with which the repeated body motions are made over time can be used to determine an outcome for a single instance of the body motion. In a particular embodiment, a probability of a more desirable outcome resulting from the single instance of the body motion can increase as the consistency with which the repeated body motions are made increases.
