Conventional vestibular rehabilitation is effective but suffers from poor therapy compliance due to boredom. Virtual reality technology can make training more engaging and allow precise quantification of the training process. However, most existing technologies for vestibular rehabilitation are expensive and not suitable for use in patients\u2019 homes and most clinics. In this pilot study, we developed and evaluated the usability of a smartphone-based head-mounted display (HMD) for vestibular rehabilitation and quantified the simulator sickness induced by the system.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec specific-use=\"heading-level-2\">\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>Two adaptive training games were developed to train discrete and rhythmic head movements in the pitch and yaw planes. The usability and simulator sickness associated with the system were evaluated in a single testing session on healthy subjects and patients with unilateral vestibular dysfunction. Additionally, the head movement kinematics measured during training was also analyzed using different movement quality measures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec specific-use=\"heading-level-3\">\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>A total of 15 healthy subjects and 15 patients underwent testing with the system. Both groups found the system to be highly usable (&gt;80 score on the system usability scale). Following 20\u201330\u200amin training with the system, healthy subjects reported minimal simulator sickness symptoms. On the other hand, patients reported a higher incidence rate for symptoms, which could have been the result of their vestibular condition.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec specific-use=\"heading-level-4\">\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>The current study demonstrated the usability and safety of a smartphone-based system for vestibular rehabilitation.
