TABLE OF CONTENTS A seated workstation should be provided for situations where continuous data entry operations occur and the operator is not required to move away from the workstation. Examples of such workstations are the office automation, remote bar coding, and computerized forwarding operations. The workstation is designed to provide an upright posture with sufficient back support, foot support and wrist support (if requested by the operator). The design should ensure that discomfort due to repetitive motion is minimized. Similarly, visual fatigue and discomfort is minimized through the design of the VDT and the work surface surroundings.
The system shall be designed to minimize user errors and fatigue. According to the accepted ergonomics practices, an integrated approach is taken toward the design where the requirements for VDT, keyboard, software, keying console are provided.
Below are the minimum requirements for the design of the VDT for Luminance:
Screen luminance: 75 cd/m 2 200 cd/m 2
Character luminance: 10 cd/m 2 20 cd/m 2
The display image shall be a non-interlaced display using black characters on an 'paper' white background with no black borders on the screen. This shall be a part of the hardware design of the VDT.
1.1.1.1 Adjacent Surfaces Surfaces adjacent to the scope shall have a dull matte finish.
1.1.1.2 Reflection and Glare Reflection and glare should be prevented through the use of a hood, optical coatings or filter control.
1.1.1.3 Finish and Luminance of Surrounding Area
