U.S. highway workers suffer tens of thousands of injuries and 1,000 of them die every year. Over time, even sounds designed to keep them safe become monotonous. 鈥淎nd that is the moment when fatal accidents happen,鈥� says , assistant professor department of civil and environmental engineering at the University of Dayton.
Virtual software Kim designed is proving successful when it comes to increasing their safety awareness. The Texas-based construction company Webber tested his program on its workers. Now that Kim is at UD, he will reach out to local crews.
In the scenario Kim demonstrated for WVXU at UD鈥檚 new , workers are asked to clean up. Holding a real broom, Kim watches his virtual self at a construction site. A front loader is moving back and forth and at some point, sounds an alarm when it's getting close.
鈥淥ur system knows, 'Oh this guy doesn鈥檛 pay attention to surrounding hazards and then the accident will happen,' 鈥� he says. The worker then virtually sees and feels the impact.
鈥淭o maximize this effort,鈥� Kim explains, 鈥渨e developed a wireless electronic stimulus system so we are going to add additional feedback during the accident, and we believe that will increase the effect of this safety training system.鈥�
Kim says there are hundreds of safety training systems. So, what makes this one different besides the fact it's virtual? He says it can measure a worker's physical movement, eye movement and pupil dilation 鈥� elements safety managers can analyze to figure out how well workers behave in dangerous situations.
Highway construction training is only the beginning
The university's new Intelligent Infrastructure Lab Manager Jack Hui Wong is thrilled about all the things this virtual space can do.
鈥淭his whole lab is very exciting, very new and also very powerful," he says. "We can do a lot of different research. For example, some application in psychology 鈥� we are going to do some human physical interaction in this virtual environment.鈥�
One example is investigating how people interpret distance in virtual space so it can be accurate in physical space. Kim looks forward to developing other safety software scenarios for firefighters, manufacturers and electricians.
Robert Liang is UD鈥檚 department chair for civil engineering. His students are using the Intelligent Virtual Lab to build buildings.
鈥淭his will open up so many opportunities for different disciplines, researchers to conduct their research and to advance their field of science,鈥� he says.
The Intelligent Infrastructure Engineering Lab was dedicated in August.
