Also, screen information should be displayed in a structured and well-organized way. Monitor Use Specifica- • When viewing your monitor, your head should not be tilted more tions than 15 degrees forward. • Optimum readability for monitor use is generally considered to be 21 minutes of arc. This corresponds to a character size of 3.7 mm (0.15 inches) at a viewing distance of 60 cm (24 inches). • You should not have to look up more than 5 degrees above horizontal or down more than 30 degrees below horizontal for normal work tasks, such as typing or reading. Document Holders When keying in data from a hard-copy document, placing it in a document holder rather than on a flat surface will make it easier to read. The following recommendations should be observed when using a document holder: • The document holder should be at approximately the same height and distance from your eyes as the screen, and as close to the monitor as possible to prevent neck twisting. Some users prefer a document holder mounted to the monitor while others prefer the document holder positioned between the screen and keyboard. • If the primary task is to view documents rather than using the monitor, the document holder may be placed directly in front of the keyboard with the monitor slightly to the side. • To help reduce stress on your neck and prevent eye fatigue, try to minimize the movement of your head and eyes while using a document holder. 14
