Abstract
The importance of systematic usability
evaluation of virtual rehabilitation systems cannot be
underestimated. We have developed a virtual rehabilitation
system with the functionality to guide a user through a
therapeutic exercise programme. Progression is determined
by users’ ability to replicate movements as demonstrated by
an on-screen character. Visual and auditory corrective
feedback is provided during exercise in order to improve the
user’s postural control and biomechanical alignment. The
objective of this study was to evaluate the usability of our
system and subsequently implement modifications aimed at
improving fidelity and ease of use. The first stage of our
evaluation involved conducting an expert walkthrough with
six experts currently researching in areas related to the
system design. Following system refinement and
modification we conducted a user evaluation study with
twelve novice users using VRUSE, a computerised
questionnaire-based usability evaluation tool for assessment
of virtual environments. Results have provided a systematic
evaluation of the system, provided information for guidance
on system alterations and will allow comparison of usability
levels with similar virtual rehabilitation systems tested with
the same protocol.
