Who had the first idea of the video game

In a very loose sense something resembling (Video Games) were on display for public use at the Hall of Science at the NY World"s Fairs. by manipulating control knobs fair visitors could make simulations of various types of atoms, based on the Rutherford-Bohr model. This was not a game but something akin to radar simulation with overtones of etch-a -sketch. still a remote (l964) forerunner of the Video Games. these machines had circular screens like oscilloscoped and did not make noise, thank God.
