To solve this problem, the project volunteer used one of the client's
own chairs. Threaded rods were installed in the hollow back legs of the
chair. These rods were connected by chains and sprockets to a reversing
variable speed hand drill. The trigger mechanism was detached and fitted
to a cord for ease of operation with micro switches on the chair to
limit the upper and lower range of travel.
The chair required only a few a minor adjustment for the client's
use. She was able to spend more time comfortably on her computer and
consequently more time at her career.
