4. Laptop dimensions - many laptops offer large screens (15" plus) and can work as desktop

replacements (giving the viewing area of a 17" monitor). However, think about where you will

most use your laptop to help you choose the best size. The larger the screen the more difficult it

will be to use this in mobile locations (e.g. airplane, car, train). There are a number of smaller

notebook and ultraportable laptops on the market. Consider issues of screen size and screen

resolution. A small screen (e.g.12.1") will be useful in mobile settings, but if the resolution is high

(e.g. XGA - 1024 x 768) make sure that you can read the screen characters and can easily use

the input device to point to areas on the screen. The smaller the laptop, the smaller the

keyboard, so make sure that you can comfortably type on a keyboard that may be only 75% the

size of a regular keyboard.

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
