Biomechanical Analysis of Opening Glass Jars: Using Kinematics to Inform Design for Improved Accessibility

The objective of this project is the development of a methodology that employs a motion capture system to quantify the motions as people use packaging. The information obtained from the developed method will be leveraged to inform package design, enhancing utility.  A review of the biomechanics literature involving packaging revealed that researchers tended to focus on the effect of torque, and little is known about motion and the use of packaging.  Experiments that do focus on motion frequently restrain subjects; this restraint has the potential to influence subject motion.  This project examined the relationship between constraining opening to a work surface and opening in free space as measured by five camera motion capture system.
