1. Tangible computer readable memory having computer readable software embodied thereon for programming a processor to perform a method for recognizing an intent of a person to engage with an application in a motion capture system, the method comprising: receiving images of a field of view of the motion capture system; based on the images, distinguishing a person's body; determining a bounding shape of the person's body, the bounding shape is represented by a point within the bounding shape; tracking a location of the person's body in the field of view based on the point within the bounding shape relative to a location in the field of view in which an intent to engage with the application is most probable; based on the tracking determining a probabilistic measure of an intent by the person to engage with the application; based on the probabilistic measure of the intent by the person to engage with the application, determining that the person intends to engage with the application; in response to determining that the person intends to engage with the application, allowing the person to engage with the application by automatically associating a profile and an avatar with the person in the application, and displaying the avatar in a virtual space on a display; and updating the display by controlling the avatar as the person engages with the application by moving the person's body.
