To decrease the strain and awkward posture associated with mousing, an input device that fits your hand and has programmable buttons is an excellent option. Flexibility and good fit are important features of mice and other input devices. In general, use of input devices should be minimized because they are a primary source of Repetitive Strain Injuries. Please refer to our keyboard shortcuts webpage and learn shortcuts for the operations you use frequently.

A neutral hand position when using the mouse is flat. The knuckles should be even to or slightly higher than the wrist. (A 5° variation is acceptable.) The fingers should rest in a waterfall position. The middle finger should be in line with the elbow. Avoid dropping your wrist. More detailed information is provided on the mouse tips webpage. (These guidelines apply to traditional mice and trackballs, not alternative devices such as the Rennaissance Mouse, RollerMouse, or touchpads.)

1. Your hand should fit comfortably over the device with the horizontal width and length proportional to your hand size.
2. Devices which tilt the hand halfway between palm down and palm up are preferred.
3. The device should minimize isolated finger and hand movements as well as force, that overwork small hand muscles.
4. Avoid trackballs that require overuse of the thumb.

You should never "click and drag" simultaneously, especially with a trackball (i.e. never hold a button while moving the ball). By programming one of the buttons to "drag" it is possible to avoid this harmful motion which is used to select areas of data or phrases or move windows. The drag button even works in such programs as Photoshop while using the various tools like the airbrush, cloning stamp, and paintbrush which normally require large amounts of "click and drag" motion.

In order to program the input device buttons, you must first install the correct software for your mouse or trackball.
