Motion capture in the BlackBox
There are currently two major systems for movement capture and recognition in the Blackbox: The Vicon system and the Kinect. There are also a set of accelerometers that you can use.
Choosing the right system
Before you begin capturing motion data, you should choose which motion capture system to use. Your choice will depend on several different factors.
What kind of movement do you need to capture?
What kind of movement do you need to capture? Consider the following:
- Are you capturing movements of the entire body or only some body parts (face, hand, arms, fingers, torso, legs)?
- Is the entire body going to be moving through a large volume of space (greater than about 5 feet by 5 feet) (e.g., walking, running, many forms of dancing) or will the body stay more or less in one spot (within a space of about 5 feet by 5 feet)?
What type of sensor is best?
what kinds of sensors best fit the motion phenomena you wish to capture. Motion capture systems use different kinds of sensors. To find out which type of sensor best suits your application, see the section on Sensor Selection. In general:
- Low-frequency movement is best captured using measurements of position (the Vicon or the Kinect will be your best)
- Intermediate-frequency movement is best captured using measurements of velocity
- High-frequency movement is best captured using measurements of acceleration (accelerometers will be appropriate)
===Do you need to p
There are several considerations that you'll have to ta Capture volume. Full-body versus gestural versus face tracking.
Do you need to process the movement data in real-time?
