On the surface, the production lines at Hangzhou Zhongheng Electric look like any other.
Workers outfitted in uniforms staff lines producing sophisticated equipment for telecommunication and other industrial sectors.
But there's one big difference – the workers wear caps to monitor their brainwaves, data that management then uses to adjust the pace of production and redesign workflows, according to the company.
The company said it could increase the overall efficiency of the workers by manipulating the frequency and length of break times to reduce mental stress.
Hangzhou Zhongheng Electric is just one example of the large-scale application of brain surveillance devices to monitor people's emotions and other mental activities in the workplace, according to scientists and companies involved in the government-backed projects.
