the 5 Tips for Using a Laptop Computer (1)

1. Un-ergonomic Laptops - the design of laptops violates a basic ergonomic requirement for

a computer, namely that the keyboard and screen are separated. In the early days of personal

computing desktop devices integrated the screen and keyboard into a single unit, and this

resulted in widespread complaints of musculoskeletal discomfort. By the late 1970's a number of

ergonomics design guidelines were written and all called for the separation of screen and

keyboard. The reason is simple - with a fixed design, if the keyboard is in an optimal position for

the user, the screen isn't and if the screen is optimal the keyboard isn't. Consequently, laptops

are excluded from current ergonomic design requirements because none of the designs satisfy

this basic need. This means that you need to pay special attention to how you use your laptop

because it can cause you problems.
