Ergonomic Trackball Computer Mouse

A trackball mouse keeps the body of the mouse still on the desk while you roll the ball to move the cursor. The hand rests in one place instead of sweeping across the desk, which is why trackballs are popular with designers and people working in tight desk spaces.

How does a trackball differ from a standard mouse?

A standard mouse moves as a whole unit; a trackball stays put and only the ball moves. Thumb-controlled trackballs place the ball under the thumb, finger-controlled designs such as the Kensington Expert Mouse put a large ball under the fingers.

Are trackballs ergonomic?

Many people choose a trackball to reduce the arm and wrist movement of a standard mouse. As with any input device, fit matters: some users prefer thumb control, others finger control. The range here covers both, wired and wireless, from Kensington, Logitech and Adesso.
