Abstract
A novel apparatus for assessing and quantifying the ergonomic position of a video display terminal (VDT) is disclosed. In the preferred embodiment, the apparatus includes a substantially planar measurement tool having a plurality of measurement indicia formed on the front side thereof. The measurement indicia are arranged so as to indicate the distance in inches above and below an alignment indicator formed at the center of the measurement tool. The tool also includes an adhesive portion so that it can be affixed to the VDT in a manner such that the alignment indicator is substantially aligned with the center of the VDT screen. In another embodiment, the measurement tool includes two visual acuity charts, which allow for the testing of the VDT operator's visual acuity. In another embodiment, the measurement tool includes an elongate measurement tape, affixed to the front side of the tool, for determining the viewing distance between the operator and the VDT.
