THORLABS Corner User Manual page 13

Once the user is seated, their seating height and footrest (if used) should be adjusted so the interface with the ScienceDesk
is comfortable – See Fig. 4.1 for guidance on preferred workspaces.
For simplicity, only one body size is shown and adaptations for other body sizes will be necessary. It is advisable
to leave legroom, which is free from obstructions/ bump hazards, under the desk.
Where operators are required to visually monitor work, displays, control devices etc., of any nature these should, where
practicable, be placed so that the top edge of the viewed area is on or below the operator's horizontal line of sight. If
possible, it is good practise to have all viewed areas in the range of 0 (horizontal sight) to 30 below that line. A maximum
angle of 45 below horizontal is acceptable for intermittent use only.
All keyboards, mice and other control equipment should be mounted and used in a manner appropriate to the task in hand.
For example if the keyboard is only to be used occasionally, perhaps during set-up, it should be placed on a side table or
even the breadboard and stored after use, whereas a fully engineered ergonomic solution would be better for an application
requiring large amounts of typing.
Lighting is also an important issue that must be addressed at the system design stage and there are many national
standards to cover appropriate lighting levels.
Finger traps should be avoided. Operation of components should not interfere with other settings or adjacent equipment.
All warning labels must adhere to the end user's national standards and should be placed in a prominent and appropriate
position.
