During the 1960s and 70s, Action Medical Research contributed to the development and implementation of special communication systems for severely disabled people. This included the Blisssymbol Communication System, which is particularly helpful when speech impairment is combined with poorly coordinated limb movement, and Possum electronic assistive technology.
Possum equipment helps people with severe disabilities interact with their environment by performing activities such as switching appliances on and off, answering the telephone and turning the pages of a book.
