In 1974 Atari released the first publicly available computer audio game in "Touch Me". If you've played "Simon Says", this is the same but electronic. Like many early games of the time, it was fully accessible to deaf-players. It may have been accessible to blind players too if the sounds played for each of the four buttons was different.
Beyond those firsts, Touch Me was likely the first pattern following game that would lead to Simon, Parappa the Rapper, Dance Dance Revolution and Guitar Hero games.
