Abstract
Methods for real time motion capture for control of a video game character is provided. In one embodiment, a method initiates with defining a model of a control object. Then, a location of a marker on the model is identified. Next, movement associated with the control object is captured. Then, the movement associated with the control object is interpreted to change a position of the model. Next, movement of the character being presented on the display screen is controlled according to the change of position of the model. A computer readable media and a processing system enabling control of video character through real time motion capture are also provided.

A method for real time motion capture for control of a video game character during game play, comprising:
- defining a model of a control object, wherein the model is mapped to the video game character;
- identifying a marker on the control object and mapping the marker to the model;
- associating a location of the marker to the model;
- capturing movement associated with the control object with a single video capture device;
- interpreting the movement associated with the control object to change a position of the model based on data captured through the single video capture device, the data captured including the marker, in the interpreting,
- for certain movements during game play, associating in real-time, the movement associated with the control object to a corresponding motion capture input stored in a database, the corresponding motion capture input is predefined to be used without modification and performed by the video game character, the predefined motion of the video game character is presented in real time and in response to a similar movement of the control object;
- for certain movements during game play, the movements associated with the control object are mirrored to the video game character without use of the predefined motion;
- and
- movement of the video game character being presented on the display screen in real time according to the change of position of the model.
A method for controlling an object presented on a display screen in communication with a computing device through real time motion capture during video game play, comprising:
- capturing movement of a depth image associated with an object being tracked through a single video capture device;
- identifying a model associated with both an object presented on a display screen and the object being tracked,
- after one or more frames are captured by the single capture device, performing operations of,
- fitting the model to the depth image to captured motion associated with the object being tracked through data from the single video capture device, the fitting includes filling a three dimensional space of the model for the object presented on the display screen that corresponds to the object being tracked;
- during the video game play,
- for certain movements being tracked, associating the movement of the object being tracked to a corresponding stored motion capture input stored in a database, wherein the corresponding motion is a predefined motion to be used without modification and performed by the object presented on the display screen, the predefined motion is in response to a similar movement of the object being tracked;
- for certain movements being tracked, mirroring the movement of the object being tracked without use of the predefined motion;
- controlling the object presented on the display screen in real time according to the movement of the object being tracked;
- and
- displaying the corresponding stored motion capture input on the display screen in real time.
