Abstract: An apparatus, such as a handheld electronic learning system, is provided with at least one multi-function, repositionable controller assembly. The controller assembly includes a first user input device, such as a joystick, and a second user input device, such as a pushbutton switch. The controller assembly, carried by the housing of the apparatus, is rotatable between a first position and a second position. When the controller assembly is in the first position, they joystick is accessible on the exterior surface of the apparatus, while the pushbutton switch is concealed within the housing and inhibited from use. When the controller is rotated to the second position, the pushbutton switch is accessible on the exterior surface of the apparatus, while the joystick is concealed within the housing and inhibited from use.
