Case Study: Eye Tracking Tackles Safety and Performance

Description

To reduce training time and improve worker safety in the high-risk environment of industrial manufacturing, research consultants from Tobii Pro Insight conducted an eye tracking study at the metal foundry of H&H Castings, a premier supplier of aluminum castings. The attention-based study revealed unique insights that will contribute to the quicker onboarding of new workers, new efficiencies in the foundry’s operations, new training guidelines, and the reduced risk of accidents.

 

“Eye tracking certainly opened our eyes to the true impact that visual attention plays in a foundry,” said Jacob Hammill, system manager of H&H Castings. “When you are working with molten metal, it’s difficult to get up close and observe how a task is being conducted. Eye tracking can bridge that gap to give our new hires a whole new understanding of the process. Consultants from Tobii Pro Insight helped us identify unique visual skills that we can now build a training program around.”

 

H&H Castings train a new employee or temp worker in the melt department twice a month on average as it’s one of the most demanding, and subsequently, the most volatile position in the factory. The average training time is one full week. “We hope the eye tracking video will save us two days per employee. Ideally this would save us 400 hours of training time per year in that department,” said Jacob Hammill.

 

The workers recruited to participate in the qualitative study wore eye tracking glasses for 15-30 minutes as they completed their tasks in the foundry. The study found that the work requires an extreme amount of concentration and focus - any sudden break in that concentration could have a disastrous effect on how workers poured liquid metal into casting molds. The eye trackers provided a close-up supervision of how this process was conducted through the eyes of experienced workers.

 

Video taken can now be shown to trainees for the purpose of instruction and the analysis of the attention data revealed steps that can be taken to make the entire metal pouring process safer and more efficient.

 

“With the attention data we were able to help H&H Castings understand behaviors that are intuitive to a skilled performer but difficult to articulate to the novice,” said Mike Bartels, Senior Research Director, Tobii Pro Insight. “We could also identify what is happening immediately before an error on the line occurs that would negatively impact efficiency.”

 

“We live life visually and through eye tracking we can produce a reliable barometer of processes, training and cognitive load,” said Tom Englund, president of Tobii Pro. “Our research consultants can apply the same eye tracking methodology to any business to ascertain the unique processes and skills needed for a more productive and safe work environment.”
