LOGITECH M570 Trackball

For anyone who has never held, let alone used a trackball, the M570 is going to look odd. It looks like a large mouse with a large gumball attached to it. Its main function is to provide a stable and highly comfortable grip for your hand while your thumb moves a small ball.

The ball on the side covers the sensor which translates the ball’s movement into X and Y axis movement of your onscreen pointer. Letting your fingers do more work, in this case your thumb, repetitive motions with your wrists are greatly reduced. The small bones and cartilege in your wrist are much more prone to RSI’s than your fingers.

Ergonomic mice in general try to minimize this by leaving your wrist in a neutral position and using your forearm and fingers to handle the motion. They can take some time to learn and are initially uncomfortable. Most users usually complete the transition in less than a week. With time you will become just as proficient as with a mouse. An added benefit is the desktop real estate requirements are much lower. Trackballs don’t need a mousepad area, they are completely stationary. You get a lot more desk to use when make the switch to the M570 or any other trackballs.
