Although I retired from the position of Design Coordinator of TADACT in 1991 I still maintained an interest in the Productions side of developing successful single disability aids that produced repeating orders. These were quite numerous and it seemed appropriate to make a catalog to explain their usefulness to a wider audience, even outside Canberra.
The individual aids were sketched by me and are shown in the Disability Aids segment of this portfolio.
