The hard hat and safety goggles are getting a makeover. Across the country, workers are using high-tech alternatives to give themselves heat vision, virtual instructions and even measure their own brain waves.
It's called augmented reality. Think of Google Glass and how it displayed information — directions, incoming calls, photos — over the wearer's field of vision. Basically, it's like layers of virtual reality projected onto the real world. That information can then be controlled with voice, gesture or touch commands.
Google Glass has stalled, but new companies are working on bringing similar technology to workers in mines, oil refineries and factories.
"It's combining the digital world and the physical world," Tuong Nguyen, principal research analyst at Gartner, told NBC News. "There are a lot of companies that are trying this technology out."
