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. The inclusion of two such
multi-function, repositionable controller assemblies, on opposing sides
of the apparatus, allows the apparatus to be rapidly configured by the
user for left-handed or right-handed operation.
