Reach zones are often used to describe Ergonomic practices in the workplace. Reach zones help establish where equipment should be located on your desk or at your workstation. Desktops can be divided into zones or areas depending on the reaching ability of the individual sitting at their desk.
Ideally tasks of high frequency should be located in the inner reach zone, i.e. directly in front of the individual where the upper arm is resting close to vertical and the elbows close to 90 degrees of bend. Typically these high frequency tasks involve the hands only i.e. typing, mouse use or writing.
Depending on the frequency of use, medium used items such as phones and documents can be located in the middle reach zones of the workstation and finally stationary and files can be located in the outer reach zone. The reach zone covers the area that extends beyond optimum reach where, using the shoulder and arm, the user can reach with comfort. You may need to rise from the chair when accessing the outer reach zone.
Ideally office workstation layouts should be arranged to bring frequently used objects closer to the user. Hopefully these tips will keep you productive, efficient and healthy while using the computer.
