Computer Mouse
Mouse Size & Shape
The mouse should fit the user’s hand and not cause unnecessary pressure on the wrist and forearm muscles. Ensure the mouse is not too large so that the wrist is in a neutral position during use.
Mouse Use
- Mouse operation can be moved from left-handed to right-handed use to minimise strain on the one hand. Ensure that button on the right side of the mouse is always used for primary functions by clicking on start (bottom left side of screen), selecting mouse and changing button configuration to switch primary and secondary buttons. The mouse may also be customised in this area including double click speed, pointer speed and scrolling.
- Set the tracking speed of the mouse to a setting that suits you (access through Control Panel on computer).
- Hold the mouse gently when moving it over the mouse pad or desk.
- Take the hand off the mouse at frequent intervals.
- Greater utilisation of keyboard shortcuts.
- If the task is primarily a mouse activity, move the mouse towards the middle of the desk and push the keyboard back.
Mouse Placement on Desk
Position the mouse directly to the right or left hand side of the keyboard. Line the top of the mouse pad with the top edge of the keyboard as a visual cue to correct placement and always aim to keep the mouse on the mouse pad.
OPTIMAL MOUSE POSITION
Sit back in the chair, relax arms then lift the mousing hand up, pivoting at the elbow, until the hand is just above elbow level. The mouse should be positioned somewhere around this point.
Mouse Alternatives
Alternatives to the standard mouse are designed to change hand and arm postures and increase efficiency. They include a wide range of operations, including rollers, pens, balls, pads and glide points. The main difference between a mouse and these devices is that the hand and arm remain stationary while the wrist is at an angle and the fingers or thumb stretch. For long periods of use this way may cause finger, thumb or wrist discomfort. Lifting the hand off the keys while operating the pointing devices is preferable.
