2 We modified our goals to more suitably match our application 1.Inexpensive 2.High Elongation (>10%) 3.Fast Response Time 4.Precision

We need: Movement through Space Rotation Real Time Feedback Can act as a supplement Reduce Errors 4 Improvements to be Made to Our System in Order to compete with existing Motion Capture Technologies

5 Our Product Could Be Used to Monitor and Provide Feedback for Joint Extension Inexpensive Output of strain Track degenerative diseases Posture Feed Back Loops Need to reduce distractibility
