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.

What kind of movement do you need to capture?What kind of movement do you need to capture? Consider the following. | ||||||
Do you need to identify individual body parts or is it sufficient to treat the body as a blob? | You could use the Vicon for this, but it's an impractical solution | |||||
Are you capturing movements of the entire body or only some body parts (face, hand, arms, fingers, torso, legs)? |
Yes | |||||
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)? |
Yes | |||||
Are you going to be tracking movement in the transverse plane of the body, such as
|
Yes | |||||
Do you need to track movements of the separate parts of the torso (the cervical, lumbar, thoracic, and sacral areas)? |
If you don't need to track precise movements of the parts of the torso, the Kinect is fine. | Yes | ||||
Will the mover be changing their frontal orientation (e.g., by turning around or spinning) |
Yes | |||||
Do you need to track both large movements (e.g., lunging, jumping, turning around) and small gestures (e.g., foot tapping, fingers drumming, head slightly tilting)? | Yes | |||||
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:

Do you need to process the movement data in real-time? |
