The cost/accuracy approach: a method for selecting filming rate for manual materials handling activities.
This paper presents a method for determining filming rate for developing kinetic biomechanical models of manual materials handling activities. Using a high-speed camera, manual lifting activities were filmed at 500 frames per second. Different framing rates were then simulated by skipping one or more film frames. The data analysis indicated that selection of filming rate on the basis of cost and accuracy trade-off is superior to existing framing rate selection criteria. The proposed method can be used for other similar activities.
