The aim of this study concerns the evaluation and
comparison of different Human-Machine Interfaces for the
control of an upper limb motorized exoskeleton for severely
impaired patients. Different approaches (i.e. manual, vocal,
visual control) are tested in a simulation environment on three
subjects affected by muscular dystrophy with the aim of
assessing the capability of the system to interact with the user
and vice versa. A Graphical User Interface shows the simulated
behavior of the exoskeleton to the user which has to perform
reaching tasks in the space by moving the exoskeleton endeffector
to defined virtual targets that are displayed on the
screen. Specific assessment of the interaction of the user with
each control interface is achieved, while a quantitative
evaluation of the usability of all the three approaches is
provided by a System Usability Scale (SUS) questionnaire. All
patients were able to interact with all control interfaces without
difficulties and to complete reaching tasks in simulation. SUS
scores showed overall good usability of the Human-Machine
Control Interfaces suggesting that the manual and the vocal
control interfaces are preferred by the subjects.
