“In a mobile environment, it is often hard to plug in and use a mouse. On the go, built-in pointing devices can be a source of frustration. For pointer operation, TOUGHBOOK Business mobiles now provide a wheel pad. You can be forgiven for thinking that a round design is no more than a cosmetic improvement over the square pointing devices that are commonly used. In fact, the round design did start out with the intention to differentiate Panasonic from other brands of notebook computer. At one glance, it adds a certain distinction to TOUGHBOOK Business mobiles. Wheel pad operation is extremely simple. By moving the fingertip clockwise near the edge of the pad, you scroll down; to scroll up, the motion is counterclockwise. In the lower half of the pad, left and right motions provide horizontal scrolling in those directions. Vertical and horizontal scrolling is free and continuous.”
