EXERCISE 10.9 [extra - not in book]

Consider a user with limited hand coordination, or one with poor eyesight. It is clear that typical computer systems, with their reliance on hand-eye coordination and highly detailed visual output, disadvantage such people. List a number of devices that have been developed to assist users with special needs, identifying whether they assist the user in achieving the same sort of interaction as a non-special-needs user, or whether they adapt the computer explicitly to help the person concerned and so move away from the keyboard+mouse+screen style of interaction.
