Introduction

Topic

The study was mainly performed in a controlled laboratory setting, where the subject constructed paper airplanes with 4 different conditions: posture of choice, slouched posture, good posture, and standing up. This mimics the setting of an assembly line.

A Microsoft Azure Kinect DK was used to measure the variations of the different postures with the given conditions. This motion capture technology is used to analyze the posture variation of the subjects.

The subjects completed the NASA-TLX survey that measured mental demand, physical demand, temporal demand, performance, effort, and frustration.

The idea is to focus on how posture of workers performing an assembly line like task relates to performance and quality of the work produced.

Why Is It Important?

In an assembly line setting, workers spend a majority of their time doing repetitive work in a constant position

Bad repetitive posture a can lead to a slouched posture which can cause Musculoskeletal Disease (MSD)

These factors may impact the quality of the work being produced

Poor posture may also increase levels of mental workload

Making efforts to improve posture among employees can lead to significant increases in production

Relation to HF/E

The following experiment is a type of experiments that has been done by many HF/E experts to determine how to make the workers comfortable

These can determine the balance between the productivity and comfort of the person while keeping safety in mind

Can eliminate short-term and long-term health related problems such as back and neck pain

Hypothesis

The group predicted that posture would have an effect on performance in the workplace.
