Work Surface
|
|
WORK SURFACE The work surface should be large enough for the screen, keyboard, document and peripheral equipment. |
 |
|
| 1. | If the mouse is used intensively, the work surface or the keyboard shelf, if provided, should be large enough to hold the mouse as well. This allows the mouse to be within easy reach. | ||
| 2. | If the work surface is limited, try to reorganise the surface layout. Less frequently usd items may be taken away. | ||
| 3. | Try to use compact equipment. | ||
| 4. | Before new DSE is installed, it is desirable to anticipate the space allocation for the workstations. | ||

| HEIGHT OF WORK SURFACE | |||
| The heights of the work surfaces for the screen and keyboard should be set to suit the needs of the user. | |||
| 1. | For optimal screen positioning, place the screen in front of the user. The first line of screen display should preferably be at or slightly below the eye level. | ||
| 2. | The screen height may be adjusted simply by placing the monitor on a stable object, e.g. the computer case. Other options like using height adjustable monitor arms can also be considered. | ||
| 3. | The keyboard and the mouse should be positioned at a height that allows the user to adopt a natural hand-arm posture, i.e. the upper arms held vertical and the forearms approximately horizontal. | ||
| 4. | So far as reasonably practicable, a height adjustable desk should be used to support the keyboard, the mouse or other input devices so that the natural hand-arm posture can be adopted. | ||
| 5. | If a desk of fixed height is used and it is too high, an adjustable keyboard shelf can be installed under the desk to keep the keyboard at the right level. Alternatively, one may raise the chair to suit the height of the table and provide a suitable footrest to compensate for the raised seat height. | ||
| There should be adequate legroom below the work surface. | |||
| 1. | Ensure that the workstation has sufficient legroom so that the user may stretch his legs or change posture. | ||
| 2. | Clear any obstructing materials beneath the work surface. | ||
| A document holder, if provided, should be stable and preferably be adjustable, and be properly positioned to avoid awkward neck posture and movement. | |||
