Just when you thought surveillance in China couldn\u2019t get creepier, you learn it has its own version of George Orwell\u2019s Thought Police.Besides the use of CCTV surveillance and artificial intelligence (AI) to make spying in real-time resemble something out of TV show Person of Interest \u2014 it can even be used to text jaywalkers a fine \u2014 and surveillance being used to record public Wi-Fi users\u2019 online activity, there are face scans required to be issued a strip of toilet paper and China\u2019s social credit system, or Citizen Score.Well, now there\u2019s news circulating about surveillance tech being used to monitor employees\u2019 brainwaves.True, the \u201cemotional surveillance technology\u201d is not (yet) capable of reading minds, which is what Orwell's Thought Police does. Still, the worker\u2019s hats or safety helmets are fitted with wireless sensors that are capable of monitoring \u201cemotions and other mental activities.\u201d Employees\u2019 brainwaves are streamed to computers where AI is used \u201cto detect emotional spikes such as depression, anxiety, or rage.\u201dYes, there are potential repercussions in the workplace for employees\u2019 state of mind. Even their thoughts are not private because if the system detects emotions that are considered undesirable, the worker could be moved or even sent home.\u201cThe technology is in widespread use around the world, but China has applied it on an unprecedented scale in factories, public transport, state-owned companies, and the military to increase the competitiveness of its manufacturing industry and to maintain social stability,\u201d\u00a0the South China Morning Post writes.Expert Jin Jia explained, \u201cWhen the system issues a warning, the manager asks the worker to take a day off or move to a less critical post. Some jobs require high concentration. There is no room for a mistake.\u201dSome workers were initially less than enthusiastic about being required to wear the hats fitted with brainwave sensors, but Jin said, \u201cAfter a while they got used to the device. It looked and felt just like a safety helmet. They wore it all day at work.\u201dScientists, companies praise the surveillance tacticNaturally, scientists and companies involved in the projects to read employee brainwaves and mine the data had nothing but praise for the practice. The article stated that the \u201cunprecedented amount of data from users could help the system improve and enable China to surpass competitors over the next few years.\u201dCheng Jingzhou, who oversees the emotional surveillance program at Hangzhou at State Grid Zhejiang Electric Power, claimed, \u201cThere is no doubt about its effect.\u201d The company\u2019s profits jumped $315 million since its 40,000 workers started having their brainwaves monitored in 2014.Zhao Binjian, a manger of Ningbo Shenyang Logistics \u2014 yet another company using the tech \u2014 claimed, \u201cIt has significantly reduced the number of mistakes made by our workers because of the \u2018improved understanding\u2019 between the employees and company.\u201dThere\u2019s not just one specific company behind the brainwave-reading tech. For example, Neuro Cap, a Chinese government-funded brain surveillance project, has been implemented at \u201cmore than a dozen factories and businesses.\u201d The device and tech has been used in China\u2019s military operations, although no specifics were provided.
