Upper-limb fatigue is a common problem that may restrict people with multiple
sclerosis (MS) from using their electric powered wheelchair effectively and for a
long period of time. The objective of this research is to evaluate whether
participants with MS can drive better using a variable compliance joystick (VCJ)
and customizable algorithms than with a conventional wheelchair joystick. Eleven
participants were randomly assigned to one of two groups.
The groups used either
the VCJ in compliant or noncompliant isometric mode and a standard algorithm,
personally fitted algorithm, or personally fitted algorithm with fatigue
adaptation running in the background in order to complete virtual wheelchair
driving tasks. Participants with MS showed better driving performance metrics
while using the customized algorithms than while using the standard algorithm
with the VCJ. Fatigue adaptation algorithms are especially beneficial in
improving overall task performance while using the VCJ in isometric mode. The
VCJ, along with the personally fitted algorithms and fatigue adaptation
algorithms, has the potential to be an effective input interface for wheelchairs.
