An integrated mouse or trackball system includes either a wired interface for the mouse or trackball device, or else a wireless receiver coupled to a wired or wireless relay keyboard. Positioning structures are included for optionally enabling the mouse or trackball device to be coupled to the interface device or receiver from either a right-hand or left-hand side of the keyboard, or from both sides of the keyboard. The positioning structures may including notches on left and right sides of the keyboard for accommodating leads or receivers, complementary pin/aperture sets for positioning receivers on either side of the keyboard or at a selected orientation at the center of the keyboard, or selectively positioned signal guiding means for guiding wireless signals from either the left or right side of the keyboard to a receiver positioned at a center of the keyboard. |
