At&T Image Analysis System Development for Manual Lifts

Abstract

AT&T Video Ergonomics Evaluator System (AT&T-VEE) is a state-of-the-art computer analysis system used to analyze the hazards of a Manual Material Handling (MMH) task. This project was funded and managed by the American Telephone & Telegraph Company (AT & T) and designed and developed at Texas A&M University. The system is a lifting analyses tool for the 1992 NIOSH Lifting Equation to determine minimal user effort in lifting an object and to standardize the outputs. This system is now capable of providing the AT & T safety specialists with clear access to: complete NIOSH analyses, pictures of the lift environment, and background information on the MMH process.

It was determined that a system, such as AT & T-VEE, was needed to reduce AT & T's MMH injuries and ensuing problems. The scope of the project was to develop a menu driven, user friendly system that would provide employees with the ability to determine the maximum weight of objects utilized at MMH tasks. In order to perform a lifting analysis, a video tape of a manual lift is first produced. The system user, in conjunction with a computer, enters employee's measurement landmarks and points of analyses, e.g., ankles, load center, weight, etc. AT & T-VEE produces a NIOSH Lifting Equation analyses, pictures and records of the MMH task.
