n-ABLER Rollerball

The large, high mass, free running ball requires only a light touch which, together with the function buttons, makes for easy navigation, selection and manipulation of objects on the computer screen.

Rollerball emulates a computer mouse but, with fingertip control and the need for only minimal hand movement, reduces wrist and elbow fatigue, requires far less effort and is less tiring. The symmetrical design enables users to work with either hand without having to angle the wrist, and the unit can also be configured for 'left-handed' operation. Its large, integrated hand support/palm rest makes work posture more relaxed and less strained.
