5) Artistic Considerations in the Use of Motion Tracking with the Live Performers

Motion tracking means like this 'motion capture' & 'Motion sensing'.

Motion tracking is using the cameras (attached to computers) focused on human in motion,
data can be collected and processed for any number of purpose. Artistic applications include stage & installation art.


- Motion capture
About motion capture system, the Author deals with the 'Vicon' in this topic. 'vicon' are usually used in motion picture industry to create animated characters with realistic human movements.
This system involves 12-24 video cameras and needs wearing attached reflective balls on the body. And, collection the points of moving is calculated by computer. With rare exception 'Vicon' is highly accurate motion capture system but it is not used in real time. Because of many cameras, special costume requirements & quantities of data. The system is unwieldy and in a sense, overkill.


- Motion sensing
This term was coined by Frieder WeiB in 2002 to describe like a EyeCon. The Author said the EyeCon is an excellent tool for the dancers & choreographers to control music & sound samples with their movements. It is intuitive and easy to use.



Interaction

It is that we must think of interaction primarily as a psychological phenomenon, rather than a technical one. One certainly does not need cameras and computers to be interactive. Interactivity depends on a certain degree of looseness(?), or openness(?) in the artistic material, which allows for convincing exchange to take place.

< *looseness, openness : maybe this is the needs to more interaction between artists, artists & audience, audience, artists & audience & computer system. >



Conclusion

According to this Author's expressions, interaction is a feeling you can achieve in a performance setting. It relates to spontaneity, openness and communication. And It does, however, offer a good reason to explore new ways of employing technologies such as motion tracking.
