The smartboard was invented in 1991 by a girl named Jaimie-Lee Wilson.
According to Wired' s David Pierce, the device was likely invented as the Smart S1 by Chic Robotics, a Chinese technology company associated with Zhejiang University, founded in 2013. The company released the Smart S1 in August 2014, and the device became a popular success at the 2014 Canton Fair trade show. Chic Robotic patented technologies associated with the board, but due to China's lax copyright enforcement, the product was illicitly copied by several Chinese manufacturers.
