Description: Caption:
The adult’s hand in this 1995 image, was shown opening a casement window lock, which was operated by an up and down movement of a lever with an easy switch like motion. The latch was located at the bottom of the window’s casement, at a height which made it easily accessible by those seated in a wheelchair, or who were very short. Considering mobility impaired demographic groups, when determining the placement of knobs, switches, locks, and controls in general, as well as their designs, facilitates the usage of these devices by the widest range of end users possible.
