Space Tracking System
Magnetic tracking system
- Widely
used
- Inexpensive
and readily available
- Limited
range of operation
Acoustic tracking system
- Good accuracy,
responsiveness and registration
- Time-of-flight
- Suffer
from acoustic noise
- Phase
coherent
- Higher
data rate => better performance
- Suffer
from cumulative error
Mechanical tracking system
- Good
accuracy, responsiveness and registration
- Easy to
integrate force feedback
- Limited
range of operation
- Do not
allow multiple users to work in the same working space
Optical tracking system
- Fixed
transducer, pattern recognition
- Trade
off between accuracy and range of operation
