ABSTRACT:
A belted-roller treadmill may be modified to serve as a potentiometer whose variable potential may be controlled by sliding the treadmill's belt (10) back and forth with one's foot. The exposed surfaces of the belt would be flush with the exposed surface of a classroom floor (190). An array of such treadmills may be connected to computer hardware for real-time acquisition of data so that an instructor may gauge his students' satisfaction with his instruction in real time.
