the 5 Tips for Using a Laptop Computer


the 5 Tips for Using a Laptop Computer


3. Laptop Posture - as indicated above, laptops violate basic ergonomic design requirements,


so using a laptop is a tradeoff between poor neck/head posture and poor hand/wrist posture.


Occasional Users - because the neck/head position is determined by the actions of large muscles,


you are better off sacrificing neck posture rather than wrist posture. For occasional use:


find a chair that is comfortable and that you can sit back in


positioning your laptop in your lap for the most neutral wrist posture that you can achieve


angling the laptop screen so that you can see this with the least amount of neck deviation


Full-time Users - if you use your laptop at work as your main computer you should:


position this on your desk/worksurface in front of you so that you can see the screen without


bending your neck. This may require that you elevate the laptop off the desk surface using a


stable support surface, such as a computer monitor pedestal.


use a separate keyboard and mouse. You should be able to connect a keyboard and mouse


directly to the back of the laptop or to a docking station


use the keyboard on a negative-tilt keyboard tray to ensure a wrist neutral posture


use the mouse on an adjustable position mouse platform


follow the postural guidelines for working at a computer workstation
