Levels of Autonomy: Ahigh-tech aid may act inway that
is not completely autonomous thus requiring the intervention of
the user himself in order to complete a specific complex task.
This is not considered a limitation of the system. Of course, interaction
with the system should be kept to a minimum in order
not to place too much stress upon the user. To face some difficulty
in a job is regarded as positive both by the persons with
disabilities and by their parents (with respect to the activities
performed by their children).Adifficulty is considered as a challenge
by the users, and by their parents as an educational exercise
having psychological benefits.
