- The VisionTek XG6 3D Laser mouse is not your conventional gaming mouse. Using just a mouse, PC users can now move the cursor and the objects along the x, y, and z axes (zoom in and out), and rotate objects and camera about the x (pitch), y (yaw), and z (roll) axes, eliminating the need for the W, A, S, and D keys
