Keyboards- Keyboard Placement – Height
Probable Risks You tend to keep your shoulders, arm, and wrist in awkward positions if the keyboards, pointing devices, or working surfaces are placed too high or too. Normally, your wrists bent up when the keyboards are placed too low and you raise your shoulders to elevate your arms when the keyboards are placed too high. Such kind of awkward postures may lead to discomfort of the wrist, hand, and your shoulder. Feasible Solutions To maintain a neutral body posture, the height of the chair and the work surface need to be adjusted. Your elbows need to hang comfortably to the side of the body with the height almost same as the keyboard. The shoulders need to be in relaxed position and ensure that your wrists do not bend up or down or to either side while you are using the keyboard. Ensure that the thickness of your work surface is not more than 2 inches. Good keyboard trays with adjustable height and tilt giving enough space for leg and foot along with adequate space for other input devices like keyboard and pointer/mouse are available in the market if you find it difficult to adjust your work surface or your chair. While selecting a keyboard tray, ensure that it has all the mentioned features The vertical position of the keyboard should be maintained within the recommended range. Its tilt can be raised or lowered using the keyboard feet to maintain straight, neutral wrist postures while making slight changes in arm angles. |
