Telephone Information Center Operator

Task/Problem

  • * Viewing the city map requires leaning over the desk; more extreme bending is required to see the northern portion of the city.
  • * The downtown area located in the middle right section of the map is accessed most frequently and is the most detailed, increasing visual demand.
  • * Light from windows and overhead lights is reflected on the glass plate covering maps and on computer monitors at many of the workstations, depending on orientation with respect to light sources.
  • * Desks are too high at 31" for many of the employees, requiring awkward reaches for the keyboard.
  • * The new chairs being ordered are too low for the height of the desks, requiring additional forward bending and standing to view the map.
  • * Placement of monitors in desk corner requires neck twisting; several of the present monitor arms are not functioning properly

Intervention
Replace current desks with workstations with height- and slope-adjustable input platforms offering forearm support. Incline the back half of the map to at least 60 degrees. The map will need to be either creased, curved, or re-printed onto 2 halves and then covered with an anti-glare sheet. This brings the hard to see top part of the map within viewing distance and allows the keyboard to remain flat on the work surface. However, glare on the flat portion of the map will still be present. The monitor should be positioned to one side of the map.

Cost
Approx. $1000 per workstation
