Ergonomics



With the science development, a new generation of inseparable office partner----portable computer, was invented. Though it brings a new revolution in modern offices, it also constitutes potential threats on human health.

Alan Hersch, director of ergonomics Lab from US Cornell University recently pointed out that the portable computer has some defects in ergonomics. Long-time use may damage our health. The monitor is too close to the keyboard. Looking down at the monitor with stiffing neck may damage muscles in our neck; If we raise the computer to a height, which is suitable for the eyes, it may damage muscles in our shoulders and arms. Generally arthrosis in the cervical vertebra will gradually appear in three years.

The purpose of ergonomics is to reduce or remove the damage on human body from physical stress. The experts advise that products designed with ergonomics will greatly lower healthy risks.
