Under the POCUS Project, interactive studies are under way to adapt
the control of the MANUS Manipulator for children and young adults
with cerebral palsy. Various control approaches are implemented and
tested with 5 test persons, ranging from 8 to 29 years, in an
integrated clinical and special education environment. With the
ADAPTICOM configuring method, control configurations are designed
which pose minimal demands on coordinated control input from the user.
They only use 2 or 3 switches and timed responses, to control all
gripper movements in space in a sequential way. For each user the
controls are individually adapted, ranging from large push buttons
on the lap board, a switch joystick, head-controlled switches, or an
individually-moulded hand-held grip with 3 integrated push buttons.
Cognitive aspects are of major importance, and much effort is invested
in guidance and training as an integral part of the study. In two cases,
a PC labyrinth game with adapted interface facilitated initial training
of basic concepts of movement control and mode switching. Experimental
results halfway the project are quite promising: a first formal
application for a personal MANUS provision is already made by one
of the test persons, while user spin-offs in related domains have
also been obtained.
