The solution was a foldable, portable bookstand, which holds an open book upright. This is loosely based on a commercially available solution that was not large enough to hold many of the client’s outsized books. The client can turn the pages with a rubber-ended stick held in the mouth.
The client can now sit up straight to read a book rather than leaning over a book lying flat on a table. Furthermore, the bookstand holds the pages open unlike the commercial solution.
